I have attended 11 track events up and down the east coast for 2 years in my 360 spider. Drive to the track, have fun mostly in blue group and drive home. 18000 total miles (also daily driver), 4 sets of brake pads, 2 sets of P zeros, now on Michlen Pilots and second set of brake rotors. Never had any stock brake fade and usually run 3-5 lbs above street pressures. Enjoy
True, you can likely avoid the race pads and expensive brake fluid if you stick to street tires and blue group speeds. There are definite advantages to that... and you can learn a lot on street tires. And if you have a spider, many organizations won't let you get out of blue group anyway. But the original poster indicated near-term plans to go to R-compounds... with R-tires, almost anybody who is fast in blue group or higher will evaporate the stock pads, IMO. :thumbsup: BTW, guys, this has been a very, VERY interesting thread. Thanks. Any other information along these lines is very welcome. :thumbsup:
I agree with Brian, there have been some very informative responses in this thread. What a tool the Internet has become for information exchange! Thanks to Rob and others like him for providing a forum like this. Gary
Billybob, you can use rake to tune your 348. Like Mitch stated, I also don't usually adjust the front ride height. I set overall ride height and rake in the shop, then tweek, if necessary, only the rear ride height at the track, reseting toe after the session as needed. Rob
Gary, When I got my 360 street car I took it to a track just to see how it was at the limit. It tended toward oversteer and cooked the brakes. I decided to go with a street/Track brake pad - Ferrodo DS2500's and Castrol SRF fluid. With the stock pads and fluid I was boiling the fluid in about 1/2 session. I also got a set of Challenge wheels and put on some Pirelli P-Zero Corsas 20mm wider in the rear (295/35 ZR 18 Rear, 235/40 ZR 18 Front). The next track day, WOW! what a difference! Zero fade & lots of grip. I ran 29 psi cold front & rear and built up to about 41 psi hot. I love the P-Zero Corsas! The car was planted and neutral and inspired a lot of confidence. I've been racing a variety of race cars for 17 years so I was prepaerd to not be that impressed with the 360 as it is after all a street car. After the second track day I came away truely impressed with the car. I find this setup to be a perfect compromise for me between street and track. A little bit of brake squeal on the street sometimes, but I think it's worth it. The F1 transmission is awesome on the track by the way.
You might want to speak to Pirelli, but their local tech told us that the P-Zero Corsa must not EVER run at over 35psi hot.
Is that "must not" as in "must not or you're losing traction" or "must not" as in "must not or it will likely burst under heavy load"??? The former would not be too surprising; the latter would be beyond surprising.
