I have done a little bit of searching around on this massive sub-forum and saw reference to at least one former Atom owner moving to an Ultima but that was a member that I believe is now selling a part completed car - I didn't see any threads discussing the following areas albeit I am sure they have been addressed many times - here goes

I have had an Atom 300 for coming on 3 years and I drive to and do 12 to 15 track days a year and I use it a little on the road but mainly its a track day car used to drive to and from track days

As those of you who have had Atoms will know the strengths include rock solid reliability, the sense of occasion/reaction of others to the car, the low maintenance costs, relative rarety and to a degree low depreciation as well as the on track ability (accepting that even a car like mine with carbon wings is largely without down force and many feel its far from a perfect handling car)

I do like the car and I may well keep it for another season but at some point I will change and therefore I am starting to cast around to see what might be my next car (who knows that might prompt a quicker change !!)

I have obviously seen Ultima at various trackdays and at Vmax etc but until recently it hadn't been on my radar but after seeing one at a very cold track day last Saturday it started me thinking it might be an option

I would not be looking to build my own - I would buy an existing car - the drivers behind a move to an Ultima would be :

- sense of occasion/reaction to the car - different I have no doubt to the Atom but my searching on here suggest that's a feature of ownership - I dont think I want to lose that
- ability to drive to and enjoy a track day here in the UK or over to Spa without the need to trailer etc am I right that a good number of users do precisely that ?
- if I went for a well built/spec'ed GTR that had been tracked to some extent and was set up for that type of road/track balanced use would I get what may be a different but still decent track day car - any ex-Atom 300 owners able to offer thoughts on the comparison/must haves on a GTR to make it workable to use in that way
- would a newer car with one of the newer fuel injected engines give me a reasonable degree of reliability or would I need to embrace frequent use of the tool kit
- I live in north london and we have speed bumps "blocking" the way to the roads I want to go out on for a blact and the route out to most tracks - will an Ultima be high enough to clear those irritating dammed things

I should say I am not tempted to revert to a Caterham good cars that the R300-500's undoubtedly are - I have a mate who loves his but they do not do it for me

Currently I have a second set of wheels with cut slicks/wets on that the track-club take to most track days for me and I would be OK running 2 or 3 sets of wheels in that way but I'm not looking to go the heavy levels of track day support I might need if I went the Radical/Juno route (or perhaps if I ran a track only car that the support team took to track for me etc etc) so for the next car I would want the drive to and from option and having relatively good reliability in the car is a strong core element of the car I am seeking - I know several folk that have gone the other route and they are happy with guys working on the cars for a portion of each track day but that isnt the kind of experience I want next time

I have of course also thought of the GT3RS or related track biased more "normal" car route - my wife might prefer that though she has done 2x5 day trips to Spa with luggage packed around her so she is "adaptable"

so..............with that brief and of course imperfect intro does an Ultima GTR sound like its worth me exploring or would you say that my short description ought to point me in another direction - Ian

Hi Ian and welcome smile

From your post, I'd say the Ultima would fit the bill well. Based on your concerns, here's my thoughts:

"As those of you who have had Atoms will know the strengths include rock solid reliability, the sense of occasion/reaction of others to the car, the low maintenance costs, relative rarety and to a degree low depreciation as well as the on track ability (accepting that even a car like mine with carbon wings is largely without down force and many feel its far from a perfect handling car)"

Ok - so in terms of reliability, it's a hard one to pin as cars vary depending on how well they're built and what they were built for. That said, as a general rule they're pretty good reliability wise if it's a decent drivetrain installation - later fuel injected cars perhaps requiring less fettling once they're setup. In terms of sense of occasion/reaction - in my opinion it's unparalelled in an Ultima, short of a Zonda perhaps smile

Re. your other points:

"- sense of occasion/reaction to the car"
- you will constantly have people taking photos of it, asking about it, crowding round it - 11/10 on this point.

"- ability to drive to and enjoy a track day here in the UK or over to Spa without the need to trailer etc am I right that a good number of users do precisely that ?"
- Absolutely no problem (unless you want to cart around a spare wheels! Drove to/from trackdays in mine as well as trips to Le Mans - surprising what you can stuff in the luggage bins etc. AND it will stay dry (in a GTR and a Can-Am with roof - but be wary opening the doors in a GTR after a downpour)

"- if I went for a well built/spec'ed GTR that had been tracked to some extent and was set up for that type of road/track balanced use would I get what may be a different but still decent track day car - any ex-Atom 300 owners able to offer thoughts on the comparison/must haves on a GTR to make it workable to use in that way"
- it's a different proposition to the Atom on track, but that means it's more usable on the road. Get a car that's track focussed and road manners suffer - and vice versa. The same deal with any car really. However, the Ultima will be faster than most things on a track and you'll still be able to drive to/from it in relative comfort.


"- would a newer car with one of the newer fuel injected engines give me a reasonable degree of reliability or would I need to embrace frequent use of the tool kit"
- a newer fuel injected (LS etc) powered car should be easier to live with in this regard but again, the caveat being the more it's tuned, the more temperamental it's likely to be. Bear in mind I have no first hand experience on EFI in an Ultima, but having had carb'd cars I'd not hesitate to go EFI next time round.

"- I live in north london and we have speed bumps "blocking" the way to the roads I want to go out on for a blact and the route out to most tracks - will an Ultima be high enough to clear those irritating dammed things"
- yes, unless they have snow on top smile Relatively decent ground clearance on an Ultima, which is not to say it won't ground out, but you should be able to negotiate most bumps without ripping the front clip off (though the seat mounting bolts underneath may be a fairly regular scuffing.

A GTR3RS is a brilliant trackday car, no doubt. But the Ultima is more 'special' (in a good way). The former isn't without it's problems either - crank main seal anyone?

Best bet is to get along to the factory and ask Ted nicely for a test drive (seeing as you're buying used), or blag a ride in one at the next trackday (not that likely in this weather!).

As I said at the start, they are a different propostion to the Atom. But, if it helps, when I took the Can-Am to Rockingham (400bhp) and there was an Atom owners trackday on at the same time, I don't recall a single one coming past (though probably because they were even more cautious/inept behind the wheel than I am! hehe ) Atoms are wicked fast and deserve their name, but are too focussed on one task for me - bit like a Superlight in that respect.

Good luck!

Thanks Stig - looks like need to do some more investigation - I perhaps should have added that the Atom coomunity scene is a good one and I would quite like to swap to another car with a community feel - that's not essential but it has kep me in the Atom fold a little longer than if it were just another car

I have gone from an atom to an Ultima with an LS7. I still have the atom 300, which I share with a friend. The atom is an excellent car especially for that motorbike feel on the road and track. It has a raw quality to it, that enclosed cars just don't have. Once we had gone through the usual atom problems (exhaust cracking, seat falling off, tank cracking, incorrect tune, Rose joints, wheel bearings, stac instrument problems etc) and allowed for the aa2 vibration by taping the connections and replacing the light housing with grp ones, the car hasn't really missed a beat over the last 6 years. We now onto replacing worn out parts, which given the abuse on the track, have lasted and incredibly long time.

The Ultima with ls7 (700+ bhp) is in a different league both in terms of it's handling, performance and that v8 noise. At Bedford, anything with a reasonable straight you are hitting 135+ and wondering why you have to brake at the 150m mark. The main straight is at least seeing 150+ and probably 170+ mph if I was brave and new the speed I could take the s at the end. The standard road tyres have significantly less grip than the kumho cut slicks but are much better in damp conditions. The car definitely has downforce as i proved in bruntinghorpe in the wet on cut slicks at 190+! anything below 110 and it was all over the place. Very stable above 120 and feels rock solid at 170. The atom starts to lift and flap at 130+.

In the cold you are always warm wink and so in the warm you need aircon.

The Ultima has required me to go back to driver instruction again to get some feel to how fast I can take corners - still learning. On the limit the Ultima is easier to catch but still demands respect. It amazes me how on properly warmed cut sticks, how easily the power goes down without the wheels spinning ( third and above) given the power. Not so with the standard road tyres for me though. I have had a few moments on track with an unwelcome tail waggle on full throttle!

Whether or not you should go from an atom to an Ultima is a personal choice. If you can, keep both, if not then the Ultima is a significant step up IMHO. Also more compliant on bumpy surfaces and warm on cold winter days thumbup ... But nothing beats that wind in your face, induction roar and feeling of wearing and seeing the car in action on the road. Tough choice. I couldn't let go of both.

Your other choice of a GT3RS is also a good one.
It's a much more "complete" car than an Ultima as you'd expect, you genuinely could use one every day.
They're very raw for a production car, great fun and very challenging, but miles away from the drama of an Ultima. Much nicer on road, good on track but feel heavy and a little slow witted on track compared to an Ultima - again as you'd expect. Not driven an Atom, been on track with loads and I suspect they're more agile than most Ultimas, but not faster with loke for like drivers.If you drive an Ultima quickly on track it's very physical, nothing quite like it.

If I wanted a car I could use 100% of the time and enjoy during that time, an RS would be top of my list if I could afford it. If I wanted a car that i couldnt use whever i wanted, but when used it left me buzzing like nothing else, an Ultima it would be.

I think if you get a used LS car, all the settling down niggles should have been sorted and there's no reason why it should be unreliable. Carefully look at the fuel systems on any you view, this can be the area that causes problems if not done properly.

Paul Storer has an LS7 and his own fuel system, runs faultlessly on track. Mine is LS7 and with a very simple fuel system - aside from the pre pump filter blocking during the first 500+ miles, it has also been faultless - 30 degree trackdays and traffic jams included. A few other owners have had minor issues when running more complicated set ups.

Btw that was me at Bedford biggrin. I saw you in the aeroed atom and meant to come over but got too engrossed in checking the engine with hp scanner and recording my exploits.

In terms of community, Ted from Ultima , Gail from American speed and Jason/Steve from autobionics have always gone well beyond what needs to be done. Like my atom, the Ultima has had and interesting journey and Ted, Gail,Steve and Jason have been absolute stars thumbup when the chips are down.

Chris Dunn also seems to be very good as well as many others I have not used. For Ultima owners, I've not fully engaged yet, but always well represented at stoneleigh kit car show and there is a wealth of info here and on various builder websites. An English version of the Americans on the atom forum biggrin ... willing to fettle their cars and IMHO seems to be more technical knowledge/advice. To be expected since most build their own!!

OP you need to speak to Mark (356speedster) he's building a car at present, Dave (Citrus7) is loooking at selling his part built car. Mark was a long time Atom owner. I'm amazed he's not been on!.

ETA - Sone & I were clearly typing at the same time biggrin

I'm another Atom to Ultima convert... In fact the part-build you mention in the classifieds is the GTR "sister" car to my Can Am and is owned by a friend. The specs of our two cars are 95% identical and we both had Atom 3s beforehand.

OK, so my Can Am isn't quite finished, so while I can't comment on the final driving experience & difference between the two, I can talk to the rationale for change.

I had my Atom for 3yrs, from new and loved it. The drama of the car, crazy looks, performance, value for money and ease of maintenance were all big plus points. Any negatives were knit-picks, so not worth discussing, in my view. I was looking for the next step and struggled to find anything that bettered the Atom on the above criteria - cars like Radicals, SP300s (track only unfortunately) and the like were the only ones that looked close, but the Ultima stood out.

Part of what I liked about the Atom was the exposure. The openness. The way it didn't look like it should be on the road. For me, the Can Am with an aeroscreen gives that same "look", while underneath moving the came on with the V8 LS engine and all the Ultima chassis hardware.

If I'm honest, I do worry about the value of the Ultima vs the Atom - it's a much bigger investment. Maintenance wise, I don't think there'll be much between the two. Aside from replacement rod-ends and a wheel bearing, I never needed to do anything more than routine servicing to the Atom, it was very cheap motoring. I used to drive it to work in good weather too.... the looks you get driving an Atom in rush hour traffic, wearing office dress, were hilarious!

For a prospective new owner, your biggest difficulty is in finding the right car, that's been built well, with the appropriate parts. There's a lot of variation out there and you will have to be very picky to get the car you want. I'd certainly urge against buying a car that's "almost" what you want, or you'll spend a lot of time / money messing about changing bits & pieces. I wasn't set on building in the early days, but after 9mths of research it became clear it was the only way I'd get the car I wanted.

There is definitely a big difference in the "scenes". The Atom club is a vibrant group with lots of activity, you won't get that with the Ultima. This forum is as good as it gets.... that said, usually any question will get answered by owners pretty swiftly, so you'll still get the advice when you need it.

I think you're looking in the right place for your next step, but only you can make that final decision. Try to get to see a few cars / talk to owners and it's always worth a trip to the factory for a chat too. I'm in the Midlands and always happy to fire up the LS3, even if you can only listen to it in the garage at the moment! My build site is here (www.facebook.com/ultima.can.am.build) if that helps too.

Good luck. Mark

Thanks guys this is really helpful stuff - clearly not such a daft idea and one to give some serious thought to over the next few cold weeks

Djlees pity I didn't get a chance to speak with you but truth be told it was freezing to death at Bedford and on the M1 going back and forth and what seemed to be decent panel fit on your car that put the idea in my mind !! Wasn't really thinking Ultimate beforehand and it was only later that the idea hit

I quite enjoyed Bedford at least taking a couple of guys out in the afternoon when the temp of the track was a bit higher and I could get some power down but I won't be doing any more track days until March/April save perhaps for a track day in Spain at that circuit near Granada that the Atom guys are trying to make happen

I will definitely be at Spa for the Goldtrack double header in June (17/18) - who knows might be there in an Ultimate rather than the Atom !!

I appreciate all the comments/suggestions guys

I think The Atom owners have summed it up pretty well.

I loved the Atom for lots of reasons, but the reliability was a key one, I hate cars going wrong and the Atom never missed a beat. After that car I had a 997 GT3 clubsport, which was an awesome bit of kit, which although I never tracked it , you could see it would be very special on track.

However I missed the attention and drama of the Atom, so found the GT3 a bit plain looking after a while (how bad does that sound). So after some head scratching I realised I wanted supercars looks, with atom style performance and reliability. After many discussions with Mark and a test ride with Ted, the Ultima seemed the perfect choice.

I would concur with Mark though, re the I Importance of getting the right spec car. Get it wrong and it could be costly to correct.

Oh and orange ones are fastest wink

Good luck

Dave
