I have stuck my Pilot Sport Cups+'s on my car for the first time. They are generally only going to be used on the track but thought i'd stick them on for the weekend.

Initially a scary experience, clearly these are very temperature and pressure sensitive. For the first 10miles of use the rear grip is appalling. As they gain temperature i can feel the grip coming back. The fronts seems to heat up quickly and give, what feels like, twice the grip as the P zeros i have on normally. Which is nice because the understeer i normally experience has all but gone. But the back still feels a bit loose, i assume it's the pressure i have.



Although i have no intention of using the cups on the street, just wanted to know if anyone else has and what kind of pressures your are/were running?

Michelin recommend a cold pressure of 25/27 on the track, i have 28/30. Do you think i need more pressure in the rears?
