Posted last week at 964 and didn't get any replies. I'm planning to burn up the PS2s that came on the car before buying a set of PSCups. Any tips on optimal pressures for:

964 running JIC suspension, RS Sways, RS ride height, -1.8 front -2 rear camber.
BBS 18x8 front with 225 PS2s and 18x9.5 rear, 15mm spacer, and 265 PS2s.

I found a few references using a search suggesting 36/42 for 18" wheels / tires on a 964, but then other references to 36/36, and others in the middle. I'll figure it out my first track day, but thought maybe somebody had some wisdom to share.

While I'm at it, once I have the PSCs on, I'll use the oem 17" Cup 1s with 225/255 Bridgestone RE050A Pole Positions as my heavy rain / extreme cold tires. Manual says 36/36 for 17s - thoughts?

Thanks!

Ron, I've found that about a 3lb difference front to rear works best for me in the 964. I run 18's also. I typically start out cold at 28 front and 31 rear and they'll usually gain around 8lbs when they heat up on the track on a warm day. If you see anything higher than 40lbs hot, then you will probably notice it starting to slide around too much.

But I'm no expert so take this with a grain of salt.

I run 17's so this may be irrelevant, but I like 34 rear and 32 front, hot.
