Not Ranked
Ant,
Another problem with large rotor dias is the extra rotating weight which slows the response time of the wheel to changes in speed and direction. This will be noticed as heavier steering effort at high speeds and particularly when racing in the wet if you have a brake lockup the wheel will take longer to respond & regain grip. The Six pot calipers usually have the piston dias increase from pad entry to exit to equalise the effective pad pressure. A few years ago I would have opted for the heavier willwoods, now Im not so sure, the lighter AP etc are probably worth it when it comes to racing. In your type of car and the shorter races it runs in I doubt the need for 6pot's. cooling is the big issue.
