Yeah the t56 clutch and flywheel are huge. And they weigh over 50 lbs together
! But that also means that you have enough surface area to hold 700 hp with a single face clutch with some civility.
I'm going with ohlins on the car. They come with 8r/6r stock. Even though I expect my weight balance to be shifted to the rear I'm going to start with that. I do like the idea of the higher rate (like the 9s your running) to limit the travel of the strut suspension up front. Instead of starting with higher spring rates though I'm going to try the 8s with a monster anti roll bar in front and a 300zx turbo anti roll bar in the rear.
mmdb, are you going to go lower than 9 in the front? What anti roll bars are you running?
