I agree. I had R888rs on my M4 with KW V3. Lots of grip but very unpredictable and very hard. At first I put up with the noise because of the grip but soon the grip runs out and then you have a set of loud (I mean all the time loud) tires with a harsh ride and low grip. I put my worn stock PSS back on and the car became so much more comfortable .......grip reduced even more.

Judging from the temps, I think these tires needed less camber both front and rear than the Cup2's among probably other things, but I'm not in the mood to go chasing the best setup for them given the negative feedback I've gotten now. I will say when they let go, it was more manageable than I was expecting, at least on these first sessions. Back to the M01 Cup2's for now. |

RE71 or the Trofeo R is probably among the better options now
The PSC2 is a good tire as well. It's unfortunate it's so expensive in the US, in Europe it's much more reasonable |

I think re71 and R888s are below mpsc and trofeos in quality and performance. |

295's will fit no problem @bmw9. I have 275 front 295 rear brand new PSC2. I will be going Trofeo R next time. I just could not pass the deal on this set of PSC2's I just got. Go for it man! Be a ground breaker

285/30 PSCup2s definitely fit up front on a 19x10 ET25 wheel. No rubbing at all with GC plates at -2.6. No spacers.

I am actually going to put on 245/35/20 front Porsche N0 and either the porsche or BMW 285/30/20 rear cup2’s.
Anyone have any experience with them? particularly front sidewall roll over issues like the PS4/PSS have with no camber plates? If so, what tire pressures are you running? |

Well, +1 on this issue. 2nd time out. Couldn't be much more diligent as far as tire pressures, proper warm up, cool down, etc. This has never occurred with any other car and tire combo I've tracked.
Fundamentally the car is just too damn fast, and the chassis too competent to be running street camber up front. Good pace in combination with a clockwise track and multiple tight right handers/hairpins, seems inevitable. My question is: Has anyone pushed through this issue, shaved/equalized ('ish) the tread in the area of the chunking? Or does it just get worse? Recalling the NT01 tread splice issue that I and many others have experienced. Looks horrible initially, resolves with time and sessions.

Me Too. This was after just one day willows springs . I did half day at the streets and 1/2 at big willow so most of this wear was in 1/2 the day at Big willow. It was 100 degrees. Tires were new with 2000 street miles on them .
Time for new tires And later, camber plates. I was sure that I would go with 275/295s but now I'm having second thoughts. Is it better to stay with stock tires that BMW and Michelin took the time to developed exclusively for this car or is there some time to be gained from 275/295s? (I'll get either torfeo or PSC2) The stock set up was very predictable and consistent, I don't really care about comfort. I want faster lap times and a consistent and predictable set up. Any advice would be appreciated. Mr VCP, you have probably tried everything. |
