Nismo Coppermix Twin - Heavy pedal with Tilton pedal box

[Komdotkom]

I'm overhauling my race car and have installed a copper mix twin (c) and a tilton pedal box with a 3/4 clutch master. Pedal ratio is about 7:1

Everyone bangs on about how the coppermix twin is just like a stock clutch, but this with the pedal box mine is really quite heavy. Anyone have experience with this? Just want to make sure that I haven't missed any common things before I change clutch masters at great expense.

Cheers.

I’m pretty sure the reference to feeling like a stock clutch is how the take up and engagement feels. It’s more forgiving, not so on/off like some. My coppermix feels a bit heavy underfoot until I start my car and the booster helps out. One way around it is getting the nismo big bore slave, also a clutch and brake shop may be able to bore out and fit a bigger piston in your stocker.

I just went from a stock OEM clutch to a Coppermix twin non-competition model. And i swear it has the same pedal feel as the original.
