I put an order in for a Spec Stage 3+ clutch (SB533F-2) and a steel single mass flywheel (SB53S-2) yesterday, and almost immediately started having the second thought that I should have gone with the Stage 2+ clutch (SB533H-2) instead.
My power goals for my '08 335xi are presently around 500whp which is within the capability of both clutches, but this goal may increase in the future which is why I chose the Stage 3+.
My concern is that once the clutch is properly broken in, a Stage 3+ clutch will be less drivable than a Stage 2+ clutch. Drivability is important to me because I have almost a two hour daily round trip into Chicago with a lot of stop-and-go traffic. I've not driven a car with either of these clutches so I don't really know if there is an issue with or difference in drivability at all.
1) Given my requirement for good drivability and that there is only a nominal price difference between the two (~$100), would you recommend exchanging the clutch for a 2+ or keeping the 3+?
2) Is there some other brand of clutch which can hold around 500whp and has better drivability characteristics than the Spec 2+ or 3+?
