Pilot Sport Cup +
Have taken delivery of (F245/R265) PSCup+ for my stock 1M.
Any experience or advice would be most welcome including optimum pressures on track. Thanks, Timbo |

That is the exact setup I had in my 1M. Tire pressures made a big difference and I realized I started too high. Here is the recommended pressures direct from Michelin's documentation on the Sport Cup. I found them to be very good:
The complete PDF of this document is located at: http://www.tirerack.com/tires/tirete...nd_Feeding.pdf This is really good info, make sure you read it as it comes from the people that built and race these. Below is an excerpt from page 14: ROAD RACING (psi) Front: 25 cold; 32 hot Rear: 28 cold; 36 hot Note: If your road-racing hot pressures are too high, start with slightly lower cold pressures. AUTOCROSS (slalom) 32–36 psi hot (front/rear) Note: Though autocross hot target pressures are the same as those for road racing, you may need to start at a higher cold inflation pressure to compensate for the lower pressure gains in autocross racing. ROAD OE pressures (Consult your vehicle Owner’s Manual.) RAIN For both autocross and road racing, you may need to increase tire pressure 6 – 10 psi over cold, dry pressures. Vehicle and driving style are important factors, so some testing may be necessary. |
