Dear Steve
Thank you for your interest in API Impreza.

The Exedy performance organic is OK around 400 hp we have a number of cars with that running around happily. The problem is the flywheel. The original is a strange affair that has little raised ' castles ' around the edge of it, and the clutch sits inside them. So it's next to impossible to reduce the weight by much. They weigh around 8 Kg's standard and given that we use the GC8s at 7 - 7.5 Kgs after we've lightened them, it seems a fruitless exercise. I would not advocate a weight much lower than 7-ish for road use on a Subaru.

So really all you can do is fit the clutch which costs
