Decent suspension and some decent size & compound rubber is all thats basically needed

that's pushing the turbo way beyond it's limits, you'll be heating the air up so much you may as well not run an intercooler

Im aiming for the same level as you by the sounds of it.

why would you need a paddle for over 265?

Ok then 19 psi will do me

safe limits for long term usage. I base this on past experience with the type of driving we do.

Also my comment is based along with the other componants, it is overall a good stage to get to. Next stage would be complete engine internals,Bigger turbo still, 444 or larger injectors and with all that would have to come a paddle plate.

I'm going to use an organic clutch (RPS Max Street) for over 350bhp, there's no need to use a paddle on a road car really, all you'll do is damage your flywheel and clutch cover, you have to slip a clutch for driving in traffic and slipping a sintered metal puk on a steel flywheel eats at the surface like you wouldn't believe. i got through a clutch plate cover and flywheel in 3k. Yeager killed 2 in 6 weeks

I have to admit - That's why I don't drive mine in traffic if I can help it! - I have the 5 plate Exedy paddle, and it's awful for traffic driving - I can literally feel the abuse to the clutch! )

Still, they transmit really well, so I'd not go back to normal if I can help it.... ...having said that, I think that a lot of my pulling away problems are from the gearing being very long in conjunction with the Z31 diff's final drive (i.e. 55-60mph in first, 100-ish in second, 135-ish in third), etc... great for top speed, but awful for pull-off!)...

Still, I'll be able to comment on this fully once my car has been "S13Eater'd", as he's kindly sorting me out a reconditioned master clutch cylinder, as mine if leaking (The slave cylinder was originally leaking, so I doubt the clutch has ever been running 100% as of yet (was slipping like an absolute b*stard at JAE, before Pukka and Shaun bled it, which fixed it temporarily)... - Once again, cheers guys!

How much do those clutches go for Danny? And where from. I had not heard of them before.
