Thanks for the updates OP - fantastic thread and well written! thumbup

I love your random purchases - like an M5, and a cheap Volvo to avoid having to get a train. laugh

I'm looking forward to next season already!

Such a great thread. @op, this pushed me over the edge in buying an 07 red 231 RX8. I had several jap cars 10 years ago. 2 Skylines then a pretty quick Evo 7. Every single car I have intended on doing a track day or other event, but something always got in the way - weddings, houses, kids, businesses etc etc etc. Been on a Panigale for last 3 years but recently got rid. Now though I am determined to do my first ever track day. Really interested in the Javelin Sprint series.

Going to hit the first event with a completely bog standard car. Will have a good service and check over at Rotary Motion first. But other than that, it’s as Mazda intended for better or worse. But really excited to finally be getting involved.

The RX8 was a good buy (so far as I can tell). 39000 miles. Has FSH with Mazda then Hayward rotary. Had coils, plugs and all new discs and pads. Not a single bit of rust underneath and has been under sealed.

Cost me £2k so a bit more than the op but will be using this as my daily too so I’ll see how long it lasts! A serious car for the money.

Thanks to this thread, I decided to take the plunge. So thank you!

Thanks smile

The M5 was less of a random purchase and more an attempt to get one before the prices move out of my reach. It's pretty rough around the edges really but I'm enjoying it a lot. It's probably going to need a bit of money throwing at it this year...

Volvo was definitely a random purchase (I spotted the eBay ad when there were 14 mins remaining!) but has been pretty awesome so far. Aside from shifting all sorts of crap around it got us over the Peak district in fresh snow a few days ago. Feeling pretty smug about the winter tyres biggrin

Again, thanks for the kind words - I'm glad you enjoyed reading and I hope you enjoy the rex! Get a picture up wink

I'd highly recommend heading over to the RX8 owners club - I don't post on there that much but they're a really helpful bunch and there are a couple of (much higher) quality track car builds over there.

It looks like Javelin have also launched a Japanese Sprint Series for next year - I think we're going to do the first round of each (Snetterton 300 and Cadwell, respectively) and then decide which series we'll go for. I imagine in reality we'll do a bit of both, so it'd be great to see another RX8 competing. I know of one other that will be joining us next year, certainly.

Not much has happened over Xmas and new year, but we have at least managed to track down the electrical gremlins. Turned out to be a fuse that blew when the boot light wires were cut...

Happy new year to everyone reading - I'll be back with a better update as soon as we get off our backsides and actually do anything with it :lol:

It feels like it’s been a quiet in bargain RX8 world, but things have slowly been coming together over the winter break. First up was a trip to Autosport at the NEC – we had a very nice chat with the chaps from Corbeau seats, who managed to sort us out with an ex-demo bucket seat and two sets of brand new Luke harnesses for a very healthy discount.

More to the point, and to make best use of these lovely shiny new things, we needed some sort of rollover protection (I'm not a big fan of running harnesses without!). Options for RX8s seem remarkably thin on the ground without spending comfortably in excess of the car's value, but we finally came up trumps through the RX8 owners club. So, a couple of weeks ago, I headed down to the Valleys with a fellow 8 owner to pick this up:

I would have preferred a full cage in all honesty, but this is a beautifully made thing and will at least give us the protection we were previously lacking if we manage to tip it over. Plus, we can run the new harnesses. It's been living in the back of the Volvo for the last fortnight, which has earnt me one or two funny looks!

Meanwhile, Pete's been doing some actual useful stuff and manages to get the braided lines we've had kicking around for months fitted biggrin

Only a small update for now, but I'm heading back down to Kent this weekend to get as much as we can done. Watch this space... smile

We’ve finally managed to have a productive weekend on the RX8 – now known as the ‘Racecat’ after bowing to the superior being that is autocorrect.

2018-02-14_10-38-30 by Ben Edwards, on Flickr

We’ve had a bit of a list to get through, and it didn’t help that Saturday started off freezing, and then ended up blimmin horrible and rainy. Still, needs must, and we at least managed to get the new EBC discs and Yellowstuff pads fitted all round. We also ran some fresh 5.1 fluid through and gave the new braided lines a good check over for leaks. The discs have an anti-corrosion coating – aside from being useful on a car that won’t move for another few weeks, they look pretty badass as well hehe

2018-02-14_10-38-41 by Ben Edwards, on Flickr

Fortunately Sunday turned out to be lovely and sunny, so we made an early start and got cracking. Prior to my arrival, Pete had spent some time prepping to drop the fuel tank ready for the cage to go in. It’s safe to say this isn’t a fun job (particularly due to the awkwardly-placed cross-braces on the ramp), but before we got too far we went for a test-fit of the cage. Fortunately it slid in fairly easily (fnar), and sat in situ it’s clear that the welding won’t be taking place anywhere near the tank. So that saves us a job!

Other things ticked off the list:

- Engine oil
- Gearbox oil
- Diff oil
- Removal of a few more odds and sods
- Get it back on the floor!

For a bit of fun we also set up the Go Pro on timelapse mode. If you’ve 3 and a half minutes to kill you can watch us variously faffing around with things, scratching our heads, drinking tea, arguing about where the camera goes and driving the ever-faithful old Volvo to the tip to get rid of all the crap we’d accumulated during the weekend. Oh, and occasionally working on the car hehe

https://www.youtube.com/watch?v=dMQ27OyCfYc


Not much left to go now. I’ve ordered a new set of coils and leads which didn’t turn up in time, and we need to get the cage mounts welded so we can get it bolted in and add the new seats and harnesses. With any luck it’ll still work afterwards! yikes

I did a set of wheels for a transit over the winter too in a very similar way, also the first time I've tried. Temps around the same, if not colder in the garage. All looked great after painting but the rust came back through very quickly when back on the van. Strongly suspect the temps in the garage meant the paint was never quite as dry as it should be even with 24 hours between coats. If you're doing the M5 wheels make sure there's plenty of heat on them to let the paint dry.

Thoroughly enjoying the thread, it was pushing my close to buying one of these but with no specialists close and replacing the van last month my fun money is no more - maybe just as well smile

Thanks Steve - yes, I'm not expecting them to be particularly long-lived, but I enjoyed doing it. Plus I kinda like how lairy they are now biggrin

With race day fast approaching it still felt like we had a lot to do. Aside from anything else, we had to get the track wheels from mine down to Pete (he’s going to be support car for the first few rounds) and the RX8 back up to me once it was back together. Pete’s been a busy boy over the last couple of weeks while I was off on holiday!

His main task was to get the new Corbeau driver’s seat fitted so the car could be driven up to get the cage welded in. I was a little nervous, I have to say, given that the RX8 hasn’t run since it was deposited down in Kent several months ago, but I needn’t have worried. It started first flick of the key biggrin



That done, he got bored and started hitting things with an axe yikes



There goes the rest of the sound deadening hehe . It’s pretty hefty stuff all told!

Now it was time to get the car back together, running, and up to mine. There was no easy way to do this, so Pete gamely made a 250-mile round trip to collect me and the wheels (turns out you can get 4 18” wheels in a Mini Clubman – just!), and come Saturday morning we cued the music…

First up, back on the ramp so we could give it a final spanner check, refit the arch liners and get the sexy new Ryan Rotary Performance coil packs installed! Out with the old…





…and in with the new! We also managed to remove the (dead) aircon compressor while we were there. It’s a hefty old thing!




We have to run with a passenger seat in this year’s sprint series, so we re-purposed the original Sparco Sprint and bolted it straight to a base. Passengers don’t get the luxury of being able to move hehe
That sorted we were able to fit the new Luke harnesses and spend a bit of time faffing around getting a fitting we were both happy with.



We got to experience a pretty weird feeling at this point – I believe it’s called ‘being finished’ confused . We took it out for a drive, just to make sure…



Yep, it works! biggrin

We celebrated that evening with beer, and spent the next day mooching around the car, scratching our heads, seeing what else might need attention. I’m sure there will be plenty to keep us busy this year, but failing to come up with anything tangible it was time to hit the road home. Two hours in a car with no interior, no sound deadening and in a four-point harness was actually less unpleasant than I was expecting, but I was still pleased to be back. The car was pleased to have a run, too – it felt great through the back roads after a hundred miles or so smile



And here we go. The first round of the Javelin Sprint Series is on the 1st April (less than three weeks away!) at Snetterton, and the following weekend we have round 1 of the sister series, the Japanese Sprint Series, at Cadwell Park. I’m nervous about both of these actually – Snet has historically been my best circuit, so I feel I’m due a fall, and Cadwell is my weakest! It’s likely we’ll do the full JapSS championship this year and dip into the Javelin events as and when diaries allow. Who knows what the year will bring, though…!

Thanks must go here to the guys at Corbeau, who – after sorting out an ex-demo seat for a decent price – not only made us a custom seat base but happily handed over a handful of spreader plates so we could get the harnesses fitted in time.

How does the cage sit on the floor of the car ?

The bare pictures look as if it would simply punch it's way through the bottom of the car if it landed on its roof ?

No pics as I'm away at the moment, but there are some hefty mounting plates welded in where the sill, arch and floor meet in (what was) the rear passenger footwell.

If anyone wants to see what Pete (who, let's be honest, is the mechanical and sensible brain behind pretty much everything we do to the RX8) gets up to when he doesn't have a shouty track car on the driveway to play with, he's started cracking on with an old Mini he had lying around...

https://www.pistonheads.com/gassing/topic.asp?h=0&...

Less than two weeks til Snet. Will we make it? Will we break it? Will it snow?! Place your bets now!

Well now, that didn’t go to plan!



Having put the car through scrutineering the evening before, we had ample time the morning of the sprint to set up cameras, check the car over etc. as well as spend a bit of time catching up with friends we’d made last year. The track day the previous day was very wet, and this morning was no exception – the practice runs were spent mostly sideways, and any attempt to put power down ended up requiring armfuls of opposite lock to keep things facing the right way! Added to this, a VX220 suffered a bout of incontinence and managed to drop oil all the way round the track which caused a bit of a delay, so by the time lunch rolled around we’d only managed one timed run each. Bearing in mind I’d managed a 2:13 lap last year in the Westfield, a 2:56.48 was pretty disappointing even if it did put me third in class at the time!

The rain finally stopped at lunch, but a lack of wind or sun meant the track was drying out very slowly. Conditions were tricky and a fair few competitors had offs of some description – often you’d find yourself heading into an apex on a bone dry track, only to find the exit was still soaking wet yikes

Run two was better for me – 9 seconds quicker at 2:47.8 and up to second in class. Run three was void after I spun off over the grass before Coram, and then we were told that run 4 would be the last run of the day.

The sun came out, the wind picked up, and we’d had a couple more stoppages giving the track more time to dry out. Pete, all credit to him, pulled a blinder and managed to get down to a 2:31.9, before handing me the car.

My last lap started well – I like Snetterton a lot (and still do!), I was finding grip where I needed and it felt like I had a quick time coming up. Unfortunately not all of the track had dried still, and as I braked from ~120mph before the left-hander Brundle, and then transitioned right to Nelson, the back came round on me and I was a passenger from there.

https://www.youtube.com/watch?v=vf-d19kqiNA

(Skip to about 1:45 if you’re impatient. Also NSFW with the volume up – I got a bit sweary)

Gutted is an understatement – the first impact pulled off the front bumper and undertray, destroyed the front wing and headlight, and bent the track-rod end almost in half. When the rear hit it took out the rear light, subjected the wing to some nasty barrier rash and pushed the corner of the bumper in far enough to put the bootlid out of kilter and leave a nice crease in the boot floor. I was mightily pissed off but fortunately unhurt – the new Corbeau seats, harnesses and my HANS device were extremely welcome and, bar a bit of aching that afternoon, I’ve been otherwise fine. Pete has mostly recovered from the heart-attack I gave him when two recovery trucks and an ambulance went tearing off down the track hehe

The RX8 has been recovered down to Pete’s (getting it off a recovery truck at 1.30am was an experience I’d like to not repeat) where it’ll stay for the foreseeable. At present we’re unsure to what extent the car is damaged – job number one will be to fit a new track-rod end so we can move it around, and take some measurements of the important bits to see if the chassis is twisted or if there’s anything else sinister lurking. While the boot-lid is a bit on the piss, the door and bonnet shut lines seem fine, so there’s hope still. If the worst comes to the worst we’ll either re-shell or break it and get something different. We’re supposed to be at Cadwell for the first round of the Japanese Sprint Series on Saturday but it’ll take a miracle for us to find something track-worthy in the next four days!

After that, we have 6-7 weeks until the next planned round at Three Sisters. I’m hopeful that’s enough time to get something together and sorted smile

So, not the update I’d hoped to give. Kudos must go to the marshalling team, circuit staff, recovery guys and the Javelin team for getting the car recovered quickly and making sure I was ok. It was a tricky recovery, and finding myself wandering the grass picking up bits of my own car was pretty surreal. Pete, also, was bloody brilliant - I was quickly dispatched to have a cup of tea and a sit down while he packed up the tools, got the car jacked up and basically organised my entire life until he dropped me home the next morning.

Few more quick snaps of the damage…

Bummer! as above, hope its to bad....


Just OOI, whilst watching your vid, I wondered what happens when you over rev a Rotary ? especially in a downchange styleee----I know the Toyota Lotus motor used to break rockers if pushed over a certain rev ceiling for example.
