I think I heard that around 2:15 for a stock M3 is a good time. I'm running 2:16.2 with suspension and brake mods.
Stock wheels and tires though, trying to learn off of those for now, and they're not crap tires. I heard that running 2:08 modded with no aero is a good time.
2:12 on a stock GT3 sounds pretty good, I think.
James, how much did the front aero help you when we went out last weekend? Just curious how much of a significant difference you felt.
