My S-2000 requires a high temperature urea-based grease.... but it revs to 9000rpm.

Is there any special grease required for the Z throw-out bearing or will synth wheel bearing grease work fine?

Try ZEP Hi-Temp TOB grease. They have both synthetic and parabolic formulas.

If you'll be taking a lot of curves I'd go for the parabolic formula.

at Monza for sure; but what about for the Helix leading into the Lincoln tunnel?
