With more HP do I want to upgrade the disc or the pressure plate?

Just curious.

I remember reading about how when aaron and others here on the board upgraded their cars with a turbo they all agreed that there defenitly was slippage when engaging the clutch. This would increase clutch wear.

So if I say added another 100hp over stock, would you all agree that upgrading the pressure plate would prevent slippage? Or would upgrading the clutch disc prevent slippage? Or would it still slip becuase the spring on the pressure plate would not be able to have the clutch stick fast enough?

Interesting I thought. I got this question after reading mazdatrix's explanation on the whole clutch thing at their website.

thx

It's a lot to do with the clamping force of the pressure plate, but then again, the characteristics of the disc effect everything as well (such as how much slip it allows, thickness, etc)

I really don't want to do both upgrades to tell you the truth, thus the question. I just want a temporary solution for the time being. When I plan on using a TII tranny then I'll go out and buy a whole clutch kit, but I don't want to waste more money than possible with an NA tranny.
meh.. I think I have it figured out anyways. Thanks for the advice sonicrat

Haha, my original disk was so far gone by the time I got around to swapping it out, it was useless, and I just picked up a el-cheapo ebay special for like $200, and that worked well for a while, then I bought a clutchnet setup.

If your disc is good, probably a higher clamping PP would be a good idea, or a 6puck with the stock plate.

it is generally wise to change the clutch disc and pressure plate together, with parts that are made to match eachother. but if you only plan to use it for a while (before changing transmission) i would either try to make the current clutch last, or just throw a cheapy disc in to get you by for the time being. then replace the clutch and the pressure plate later with a better unit.

if you buy an aftermarket performance clutch like an exeddy you get a heavy duty pressure plate and disc with a higher coifficient of drag
