9" presssure plate
 

I heard the 2+2's pressure plate is 9 1/2" i am planning on putting a 5 speed into my 2+2 and i was wondering if it would work on my car as long as i use the 5 speed out of a 2 seater.

you can use any gearbox but you must use a 2+2 flywheel and pressure plate

is there a reason as to why the coupe one won't work?
Is this a durability issue?

No, the larger pressure plate has more outside "leverage" Basically it engages harder. The larger flywheel/pressure plate combo was used in the turbo ZX (2 seater Turbo and 2+2 Turbo the same) and also the 2+2 n/a just because the car is a little heavier and they figured if you had 4-people in there your clutch might slip if you tried to engage it from a stop on a steep hill.

The larger diameter clutch has more cyntrifical weight and therefore takes a little more power away from the wheels. You'll get more power to the wheels by using a 2-seater clutch. If you drive by yourself most of the time, that should be just fine for your car. If you want a clutch that grabs harder then go with the 2+2 clutch.

From experience, with my 280zx 2+2 I've had four people in the car on a hill, when I engage it in 1st I felt it slip a little. So adding a lot of weight to the car does make a difference. Also, people have built some pretty high performance motors and used a 2-seater clutch with no slipping problems. its your call

Ok thanks alot! I was pretty sure it would still work and yes i usually drive with max 2 people. I'll be lightening my car by about 200lbs anyways so that'll help too.
