Would you say these are too harsh and loud for anything more than a weekend/track toy?

well, I've run over a drain cover a recently which had a certain "DIP" to it, nothing substantial and the feeling that shuddered through the whole car made me wince. Now my car does have track 3 way kw competition suspension so its always been harsh but it definitely worse with ALL of these type of semi slicks, from what I'm seeing these would definitely be streetlable, but the whirring noise that sounds EXCATLY the same as a 888 is extremely annoying, again, one of those things with these tyres, from cold they seem pretty st tbh... i prob won't be able to comment on wet weather performance but looking at the tread pattern i think they'd be pretty decent ( see my first pics) .

These are the real deal when it comes to dry grip however... no doubt about it.


But to answer your question the ride is very harsh with these in place, which i expected tbh.

[Beedub]

Again massive thanks for everyone adding in on this thread. Looking forward to getting these on the track where the slip angels increase, I'm interested in a comment earlier that suggest these are too happy sliding around ( Not that i do that intentionally , my car does have a good gob of power and exiting with decent throttle application has the tyres slipping easily, i look forward to putting some real stress on these, with my cars weight 1350kg+ i think any pitfalls will quickly be realised i agree with whats been posted on scrub in, they need a good few miles.

I guess that answers my question as to their suitability for sprinting.

hmmmm..

my first track outing this year is a sprint session at curborough on the new figure 8 course. i would think with a higher ambient temp they'll be better from the off, from my experience all these type of tyres aren't great from cold, and come with the territory.

I would very much like to hear your feedback on them after this sprint.

I'm currently using 888's and there are maybe 2 events left in them before I have to replace them. Although I'm happy with the performance of them, like you and many others, I'm finding the price of them hard to justify.

i feel your pain.... i actually got to to the point this year where i genuinely couldn't afford the premium price which forced this move and.... well..... I'm VERY pleased so far and I'm pretty much convinced my tyre snob days are over, all its done is cost me a fortune.

Don't know if this makes a Diff to people but if you have a tight arch clearance be careful on ordering, my rear 265 actually measures 273 and my front 235 was 241 in total section width, they run wide with a very square shoulder like a 888.

[Beedub]

spent ALL day on these yesterday at the track and put the hurt on them, the really took a beating....

will write a detailed review later. Managed a time of 1.29.3 which i was told in my class is only beaten by a 400+ hp evo X, so fastest on the day for class and second overall on the leaderboard, not quite fair class ratings with the 4wd benefit, usually 4wd has it own class, this was also my First time around the track on the new configuration so overall very pleased with the result...

as a summary the tyre don't give the 888 confidence for me but jesus no high end ROAD based tyre for example PSS, PS2, the new continentals, goodyears are matching these for dry grip again not really a fair comparison due to their semi slick nature but just giving some examples.

i would say these are 70% of the 888 tyre for huge cost less which for me cant be ignored, i WILL buy again but in the meanwhile need to change some settings on the car itself, with a brave pill taken i reckon a 1.27 is possible, I'm braking early and taking corners with a too much caution, however cur borough has no runs offs so I'm always alittle wary,

[Beedub]

Edit..

having experienced these on a lighter car..... wow... wow wow...

my cars lardy ass was putting alot of stress on them. on a lighter car ( TVR) these felt pretty special.

Ahem...

If you're a big fan and are going to write something up anyway, I'm happy to stick it on the site as an article...

You must have gone out with Jony (Rib) then in his somewhat incomplete Chimaera 430 - his 1.25.5 was the fastest of the TVR group despite having the second least power at around 275 bhp. Just goes to show that on a sprint course handling, driver skill and so on matter more than outright power. He is both smooth and aggressive, something I struggle to be (both at the same time, I mean)

I was there too in the slightly battered navy Chimaera (I came and had a look at your car during the day - superb piece of engineering) and I managed a 1.28.0 in the morning session on 300 bhp.
I noticed that all the TVRs ( except the Tuscan that broke its steering rack) were quicker than your BMW. You have a lovely car, but on that tight twisty track you seemed to have trouble getting the power down usefully. I know I had trouble both getting the power down AND keeping the bd on the track!!
I watched a few of your laps and I could see you were struggling with getting the power down usefully. I was faster last time out than a 500 bhp 6.3 litre LS engined TVR for the same reason.

And the Caterhams had us all thrashed - 1.21 was the fastest, but he is an ex-karting champion.

Hi Trev

I was on 888s yesterday too, and they do heat up quickly and hold their heat well. The only downside (apart from wallet-bashing) doesn't affect TVRs - they tend to overheat quickly on heavier cars.

I am presently trying Federal 595 RS-Rs on my Chimaera as an alternative tyre, both for track and fast summer roads. I did the TVRCC track day at Cadwell Park on them - brilliant, as grippy as the 888s, no overheating, very quick to warm up, and more progressive when provoked, so you know what the car is doing rather than finding out via the armco.
And £300-400 a set, not £700. Only downside is I have been unlucky and have a faulty set of rears, which are going back under warranty. Fronts not affected at all. Talking to ATS, it's a problem in the moulds in manufacture and can happen on any tyre of any make, so don't let that put you off. It manifests itself as a shallow crack across the width of the tread, presumably where two tyre sections join. Pic below:

yeah i agree I'm pleased i hit under the 1.30 barrier BUT being my first time on the new configuration I'm actually pleased, with a little more work, i fully intend to slash that time further, watch this space :-)
i remember talking to you, very nice guy, and nice people out in general, traction was a REAL issue, I'm going to back off the aggression alittle on put some trust in and for it on the cross over section.... I'm braking way way to early on big braking zone too.... lots of time to be had!! I'm pretty certain ill be back next week for another go :-)


weight is also a large problem for me, but the car feels good...... But... on a close inspection of the tyre.. what did i find???? pic coming shortly..... Put it this way, explains EVERYthing i was saying to everyone that asked about the tyres on the day.

EDIT..

so on discovery it seems i have been shipped the "road" version of the tyre... you have the track TWR 120 and the road version TWR180 i never checked tbh but its clearly marked on the sidewall, so to get that time on those compound of tyre.... I'm actually quite pleased , however, let me get these swapped over and .... let me have another ago.... i think that time is about to tumble :-) i actually said to jonny , you car is has different level of grip as he took me for a passenger lap, I'm sure he can confirm that comment, even still the road version impresses me even more now, they took a bashing.... but they struggled to deal with my power output and got hot quite quick....

i'll get them swapped to the track version and lets talk again in a week :-) it will be nice to have a direct comparison with the road/track version.




on your 595rsr, i don't think that is a mould fail, as I've read year old threads saying the same thing... I'm pretty certain its a flaw with the design of the tyre, and I'm certain it will happen again.

Thanks for the feedback.

I appreciate that they heat up nicely on track days, i.e. after a few laps, but what are they like cold. Do they get heat into them as quickly as 888's?

i'll definitely do so, and also a direct comparison again the track version of them can be added in a week or so's time.

The 595s? As far as I could tell, yes. I always let the car warm up the first lap, but I didn't notice any lack of grip. They drive like 888s on a TVR in my opinion.

[Beedub]

update : tyre supplier has said burn through the set i have and receive 50% off my correct order, I'm happy with that :-) Don't think it'll take long burn them through!! lol!!

[g40steve]

The crack just wears away, had it happen on a couple of tyres.

The NS2r's are noisy on road, the Feds give a better ride for day to day use.

Thanks Steve. Just done 600 miles on them since Saturday. I will have another look. What car do you run?

[g40steve]

MX5 mk3, been tracking it for 5 years now.

All setup by Roddo on here.
