Wow.. Quick response:

The Nismo disc is 250mm, larger diameter than the stock 240mm.

The disc is spring center full face.

The Nismo clutch kit is similar to a stage 1 high performance kit.

If you're looking for racing use only, I would recommend figuring out what the expectations are of the clutch and go from there... Nismo would be good for street/track combination. Probably not enough for Drag race only or a Track only car. You'll probably want to go with a 4 or 6 puck unsprung disc but that would put a lot of stress on the drivetrain.

I have yet to see an aftermarket gearset, driveshaft, and rear end for this Z34.

Personally, I think the Nismo Clutch kit & flywheel setup would be the best on first time fitment, drivability, reliability, and performance for the dollar.

Thx!

Dan, no comment on you or your company, you guys are great in my book, but the way you describe Nismo is hardly the way customers expect to be treated... ;)
