Is this for a track car dan? Will it be stripped or not? On your new coilovers?
Lol, you dont need a professionals opinion mate. Do a few laps of the track, and take a pump with you.
You'll soon see how much scrubbing you're getting on sidewalls, and how planted the rear feels, and change them to suit.
Thought you'd done plenty of trackdays before?

Im running 32 front, 28 rear on 15" yoko paradas for road.
On track i put the fronts up to 34ish, but keep the rear the same...
Stripped bare, 15's, ledas on a track set-up. Id say experiment though. Throw it at a few corners, see what you like. Its amazing how much difference tyre pressures make to handling.
