I went to Buttonwwillow Raceway last Saturday. (man, it's lightly snowing in Bakersfield right now!) anyway, drove the ZO6 very hard, about 45-50 degrees OT and dry. Dash display shows trans high temp at least twice during sessions (four half hour each). Any one seen this? I am planning on replacing the trans fluid with Redline syn oil. Any known objections to this? Also cooked my brake fluid, very soft pedal now, changing to Motul 600 (and either Performance Friction or Wilwood pads for track days only). The car definitely did not stop as well as I thought it would or have liked. But over all it performed very well considering it is totally stock with 2K mi. To any one who is familiar with BWR, I turned 2:17"s by a handheld stopwatch on no. 13 (full track to Star Mazda clockwise using the busstop) which was at the top of my group with a modified Camaro and NSX I think. This would have been in the middle of the fastest more experienced group ( a number of trailered cars, highly moded). So, I felt pretty good, but man this 49 yr. old body is SORE! BTW, the fastest car there was a 01 ZO6 on the lowered settings ( nothing removed ) with camber at 2.5neg front and 1.5neg rear, riding on used Goodyear slicks, with a roll bar, Motul 600, Wilwood pads, afaIk nada mas. Turned a 2:019! Very fast for any car, especially a street car. I was impressed. Great fun.
