zooming around laguna seca yesterday..
need new brakes after yesterday. They lasted 3 track days and 5000 miles..DCT started acting funny at the end of the day and threw some codes.. It didn't like cresting after the bridge before turn 2 and shifting. JB4 and 100 octane with DCI hung pretty well in the straights with some much faster cars.

Were you on map 1, 2 or 5? Oil temps?

Wow, cold... I'm not able to stay below 250 under hard driving @ an ambient of 80-85 degrees. Does it depends on my standard 35i BMW oil quality? Castrol 5-30 i believe... Do you use a diferent oil?

standard 5w-30... 35is has better cooling and the car stays pretty cool from oil temp perspective. I also had maxcool turned on on my JB4.. brakes on the other hand is a different story. my rotors were glowing especially on pics after turn 2.

I thought they weren't that bad either, until I threw on some real tires . . . regardless, glad you had a ton of fun and what a great looking car.

I have the michelin pilot super sports on my M3 and Pirelli Trofeos on my Ferrari.. the track is definitely a good way to burn off the RFT's though..

What speed did you achieve by turn 2?
I saw 120mph riding with Scott Pruett in a Dinan M3 last year. I'd guess your JBZ4 iS got on the straight at 40-50mph, hit 100 by the bridge and 120 before braking for turn 2.

indicated about 125mph but the speedo is probably pretty off.. I also didn't lift over the crest and the is gets a little light and scary..
