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

To get decent life out of them, you'll need to run at least 3 degrees camber in front.

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.

Thanks for the advice. I ran according to the recommendations and it did provide improved grip and confidence in braking-cornering than stock PS2.
