I might recommend the RRE "no-name" clutch. They have an Evo clutch by the same name, but it was developed for 2G's as a "sleeper" clutch to prevent dealers from voiding warranty in crankwalk issues because of a painted "aftermarket clutch" being installed.
In any case, it isn't really listed anywhere on their site, except in the comparison table, and it's referenced in the Evo no-name clutch description. You have to actually call them up and ask about it - they may still have some in stock.
It's a 2700 pound pressure plate they had custom made with diaphram angles to make it a bit lighter on the pedal than the ACT 2600. Used with an ACT street disc, holding power should be about comparable. I haven't had a chance to try mine out yet, but it they've never had any complaints.
Clutchnet actually makes some of the best clutch discs around, even if their pressure plates are about on par. I'm planning to run the RRE clutch with a clutchnet sprung 6-puck, with bonded friction material (the last part is important - most street clutches use marcel, which is a spring material to spread the "friction zone" out and make for smoother clutch engagement - new cars with easy clutches use a lot of it. The problem is that the friction material can only be floating, riveted in place instead of solidly fixed. Bonded discs can take much more abuse, and are normally only found on unsprung discs, but if you call and ask, clutchnet will make a sprung one for you.
Anyway, so far it's the best clutch setup I've come up with that makes the fewest compromises without going to a twin disc. We'll see how it actually plays out.
