I never had any overheating issues, although our ambient temps way up North are lower than California.

I have been able to do much better laps with the SC. I saw appeciably higher speeds on both the front and back straight with front straight speeds increasing by 30kph on the front straight. The only place I saw any slower times was on the entry to the front straight that was a 2nd gear turn, so traction is an issue here with street tires. On r-compounds this was not a problem, so beyond requiring early braking points I didn't see any deterioration of lap times.
Are you 6MT or DCT? Both of the 600 kit cars I know are DCT. Not sure that has anything to do with it, but just curious. Regardless, I'm glad the intercooled kits are performing well for you guys. I guess there aren't many guys with 535 kits doing many track days. I'd love to hear more from those guys.
E92 M3 sold. S2000 acquired. Cayman GT4 allocation obtained.
