I'm thinking of replacing my stock clutch with an ACT street clutch with these increased pressure plates do I need to replace the slave cylinder?

ZX2-HDSS: pressure increase 34% over stock
ZX2-XTSS: pressure increase 75% over stock

Also, I know that I have not added a lot of HP but the OEM clutch could not really handle a stock engine, and now I'm adding a cold air box, and header will the 34% increase ACT kit be enough?

Thanks Al

I would recommend replacement of the original clutch master, slave and flex line anytime after 100K miles when doing any sort of clutch job.

Well the car only has 77,787km on the chassis (48350 miles), so I was more worried about the strength of the slave cylinder when pushing the stronger pressure plate in?

I'd probably still replace the flex line with a SS one, but with that few miles, I would think the stock ones would be fine.

The few FCs I've seen with upgraded pressure plates needed new clutch hydraulics. (Had mushy feel and engagement near or at the floor) However, I think it was simply a matter of the extra pressure spotlighting an already weak system, as both cars had over 100,000mi on the clock. Replacement with fresh stock components cured the problem in both cases.

Mark, where can I get a SS flex line, or do I need to get one made?

Corksport has them for $16 last time I looked

anyone know where i can get a new slave cylinder? local parts store?

asherwood

Thanks Mark, found it there, $18.

Interesting fittings in the picture, I thought that they were threaded on the ends...I was going to get a local shop to make one for me, but from the pic, probably not possible.

nevermind i need a master cylinder not slave.
