Haven't got to the point of checking tire temps yet. I do inspect the wear to ensure I'm getting as much Patch on the road. The R888's have a very clear arrow on the side wall to indicate your wear-point and adjust tire pressure according. I typically will have 1 to 3 lbs more pressure in the rear to help create some needed oversteer. I target the fronts to be around 32lbs hot but watch the wearing as well and adjust the rears from there as needed. Some days I'll chase tirepressures all day with the changing track conditions.
The only suspension I have so far is Eibach springs and adjustable sways. Front is adjusted loose and the rear tight, again trying to counteract the understeer with some oversteer.
Your correct about the feeback- When running the P-Zero's you could learn to listen to them and they would talk to you. The R888's don't say a word. But you change to feeling and build up a trust with them. 4 wheel drifts and enduced oversteer become predictable and manageable...most of the time. If you drop two off into a wet sand trap don't expect them to to be your friend when you get them back on the pavement
