tarox are garbage, go for Nitrac, BennyR56 can sort you out
Thanks. I'm asking as it seems a lot of money. I have some stock sized Tarox discs on the my back of the R53 and they've held up pretty well, years actually, so no I've no bad experience with Tarox.

Anything will hold up well on the back of an R53 as it gets so little braking force :lol:.

Knutstorp

The GP2 arrived at the NMCS Summer Meet 2018 (Ring Knutstorp) in one piece, rocking fresh discs all round (EB pulled the trigger on the Tarox before I could stop him), fresh brake fluid and fresh engine oil. It ran well but destroyed two Kumho V70As (a combination of worn tyres, very hot conditions, and excess tyre temperatures). And then suffered a worn wheel bearing. Fukcen MINIs.

We haven’t done much to the set up with the GP2, it’s basically just about wound down as far as it’ll go, and it’s running lightweight rims with less offset and sticky tyres. There was one other (modified) GP2 with a much more aggressive set up (Comptech top mounts anyone?) and it was pretty quick (Knutstorp is a pretty technical track, lots of corners, lots of elevation changes, short straight). So I think it’s time for adjustable front top mounts, adjustable rear camber arms (for more camber front and back) and a bigger rear anti roll bar (for a bit more rotation).

EB managed 42,000km on the original clutch, and the stock discs lasted about 50,000km. And Bob alone knows how many tyres: this must have been the third set of V70As (there were two blowouts in Dubai), most of a set of Nitto's (they're only good for one more trackday probably) and some AD08s for a while.

The rear brakes (stock calipers, fresh stock discs, Carbotech AX6 pads) are now squealing and squeaking like bastards: how do you re-bed rears only? Did we manage to warp them at Knutstorp?

Take the pads off, give them some sandpaper action and reinstall..? Carbotechs do squeak though, at least the XP8. Not much you can do about it. EBC ships their pads with some heavy duty rubber stickers that you're supposed to stick on the back side of the pads. Maybe something like that could help?

No new complaints from the braking front so maybe a bit of driving was all that was needed?

The GP2 is now back on the chili red OZ SuperTs (they're looking a bit tatty, like track day rims that have been dropped on their faces a few too many times) and Nokian HKPL R2s.

And apparently an MTGF GB Whiteline rARB is wending its slow way to Espoo for more oversteers. Just in time for winter!

MTGF Group Buys (ie Micke) have now provided a set of Hardrace adjustable rear control arms (they look pretty chunky) as well as the Whiteline rear anti roll bar. Just looking for a set of top mounts now and some time in a warm garage.

Updates on the rims and tyres

• Summer rims: Matt Graphite OZ Racing Ultraleggera 17x7 ET35 with 215/40-17 Toyo Proxes CF5 tyres (sourced in Sweden after two of the Kumho's failed at Knutstorp because EB overheated his tyres.... :scared:)

• Winter rims: Chili Red OZ Racing Superturismo 17x7 ET40 with Nokian Hakkapeliitta R2 215/45-17 Nordic friction tyres

• Back up rims: stock GP2 17x7.5 with Yokohama Advan Neova AD08’s in 215/45-17

• plus some tyres: 3x OK Nitto NT01 215/45-17, 1x quite worn, and a pile of about 5-6x worn Kumho V70a 215/40-17s (maybe we'll have enough for a track day?)

Next year, we'll swap the Yokohamas onto the Ultras for summer and run the stock rims with Toyos in the spring and autumn (when you need some tread).

Last Saturday got to see the GP once again. EB assured that next year I'm going to see it in action. I'll be picking up my lonkeros at the same time :laugh:

I'm going to nab the Nitto's, or maybe 4 Kumho's, for the 17x7 Enkei SC15s so we will have - between us - at least one spare set of rims and tyres for the track.

The GP2 has been killing tyres recently. The second Kumho V70a blew out on the highway, with another long gash in the sidewall ... so the car is back on stock rims and 215/45-17 Yokohama AD08s. The climate is notoriously harsh on tyres and they are getting to 3 years old, but no one likes a blowout. We're thinking that AD08Rs are the way forward: sticky, resilient, can handle lots of camber... now it's just to find some.
Just re-reading my own thread. EB's managed to destroy 4 of these OE Kumho's (two in Dubai, two in Sweden). I think we need to manage the pressures better. Or get more resilient tyres.

And thinking about the future, I think that two things need to happen. Add buckets and a cage. Keep the weight the same. Recommendations?
