180mm clutch

[John1.4]

iirc they start to give when they reach about 220bhp and / or 200lbft, it'll all be relative though, they may 'last' past those figures, but not for long, your best bet if you fancy running a little more power is to fit one of the 200mm clutches from a saxo/106, a couple of the people on the AXOC run standard 200mm on their turbo's, albeit the peeps who run 300+bhp use paddle / ceramic clutches

hope this helps,
