i was just wondering what are people using now in there in track cars? we use castrol srf in our rally cars but i now need some for my ek9 so was just seeing if they are any better ones out there, i know the motul rbf 600 is similer to the castrol while the ap racing prf660 has a lower boiling point, any others worth looking at?
