Center Caps/ Corsas

1. Need Center caps because I forgot to take off yesterday at LRP and 3/4 came off. Got 2 back so need one.

2. Pirelli P Zero Corsas. Figured yesterday was a good day to try them at the track because it was rainy and wet in the AM and drying throughout the day.
Some observations. Pretty good on wet track but as it dried and pressures rose, grip went away BADLY. They were no better than the P Zeros from my 2010 on the wet track. Critical high numbers were 35/36. After several sessions for the day , I had them back to same pressures as my R888's ~32/34 hot. When they got hot and started to slide around, pressures climbed like crazy. I was not impressed with the Corsas on a dry track. They howl like a bastard. When hot they got wicked greasey. No wonder Pobst had his hands full in that Best driver's car comparo. If they had him running 35/38 cold, he was driving on tires that were ~41/46 hot!!!! Even at 32/34 I felt they were no match for my R888's. Felt like street tires being massacred at the track. Now 1 note that I acknowledge. These are from a 2011 Evora S so the tires are 3 years old. If they degraded that badly, I guess that could be part of it. Regardless, I'm going out of my way to terminate them before cool fall temps kick in. They are DEFINITELY NOT worth $200 more/rear tire than the Toyos!! Their only advantage is they are much quieter. Ride actually similar. Bottom line, I was disappointed. I expected serious performance out of that 60 wear rating. IMHO they are not worth their price and not worth replacing with them. BTW I was directly observed running wide in multiple places where I usually nail apecies every time and they heard the tires howling in protest with great amusement.

Hmm, the temps here aren't very high and I've always had relatively fresh Corsas but I've never heard them howl. Generally I can get them to a point where the car will under/oversteer predictably and I start using the throttle to steer the car in the corners. I do run lower pressures then what Lotus suggests (I run 32/35 cold) and the temps/pressure does climb a lot but I only had issues with crowning in the rears when I ran 39 cold.

I don't know if they're really worth the extra cost, there are a few different Toyo Proxes tires (requiring smaller wheels) that would perform as well for less cost.
I'm talking track, Pacific Raceways and The Ridge in Wa. On the street they don't get warm at all, at least not unless you're being reckless. I'm waiting for this set of tires to burn off before I switch to something else. I'd prefer to have a set of track wheels (18s) with something more reasonably priced and then just put Michelin PSS on for street use.
