[Driv200]

I think it’s a miss not having a sub forum for the ultimate track car. So, thought I would start a thread where track focused guys (NASA, Grid Life, SCCA, WRL, Optima, HST, Time Attack, Track Groups) can find track content related to ZL1 1LE’s.
==If you don’t track or if you drive your ZLE daily, this may not be the thread for you. Welcome all of course, but please be track experienced to comment==


Anyone have experience with these questions!

Best square tire size set up when using Pirelli take off slicks. What’s the widest front size you can fit? If stock, then how does that work as smaller width in rear and car handling? Best to go with stock sizes and not square?

E85 gains? Need additional fuel system upgrades? Did you change injectors? Noticeably better cooling? Better performance? What psi on what pulley?

Any overheating on 20min summer sessions? Engine, trans, SC?

Any brake fade? Best track pads for stock ZLE calipers?

Favorite track tire thus far? R7, OEM, Pirelli slicks, etc...

Best rear harness/roll bar? What race seats work best?

What size memory stick for PDR?

Brake fluid using for track?

Oil & trans fluid for track?

What spare parts do you take to every event?
