Exedy clutches

[trackratZ]

I'm curious how durable are these OEM clutches when pushed hard? What typical miles could we get out of them? Those that drag probably abuse them the most, but still, what can we expect? Are better upgrades needed and available? Known issues? Any inputs help and those that have replaced them.

Also curious. I read they can take 500 hp.

Durability of a clutch has so many variables.
Most important factor is driving style, as not being aware of or avoiding what affects the cltch/flywheel in a negative way can kill a reinforced clutch faster than shifting/driving appropriately on an OEM clutch. Although Exedy IS really good kit I'm certain you can get a beefier clutch that will last longer under the same driving conditions.

A lot of people like going with a lightweight flywheel, but they do tend to wear faster due to the inherent nature of their design. A heavier flywheel is actually marginally easier to engage and disengage. As they're lighter, they don't have as much rotational inertia(?), so when you disengage the clutch the engine RPM decrease faster than with a heavier clutch. Absolutely no reason why a daily driver shouldn't have a lightweight flywheel, but the pedal pressure is a little more finicky, and they're not going to last as long. For a tracked car, and especially a track-only car a lightweight flywheel is the way to go.

Probably other things, but in my head the other part is clutch pedal pressure. You can find a clutch that you can rip at the track and will last a long time, but will work the heck out of you. In my opinion, a heavy pedal can be more of a turnoff than longevity. So you got another 6-9 months out of a clutch. But your left thigh is now twice the size of your right.

I think the stock Exedy has really good feel for normal street driving. I didn't do any really high RPM shifting or use launch control until after the Nissan break-in mileage. The biggest mistake people make with any clutch is asking too much before the disk, flywheel & pressure plate surfaces mate.

BTW, launch control also allows full throttle up shifting so the stock clutch must withstand some abuse along with engine management help. Each launch control use gets stored in memory so I don't recommend overdoing it, LOL!
