I used MOTUL DOT 4 (RBF660) in my MPS with only a pad upgrade, it held up great and I never boiled the fluid on the track.

I also used it in my VE SS after the Brembo uprgade and in my DC2. Both preformed faultlessly under moderate

I am currently running Pernite DOT 5.1 in the Forester because it was all I could get on short notice, and it had held up great on several track days in 36 - 38*c heat. It has only just started to discolour slightly.

I will be putting the Motul RBF660 into the clutch and brakes of the Forester when the Penrite degrades too much.

Motul 325*C Boil > Penrite 296*C Boil
