Which clutch?

Well this question is for my brother's Turbo RSX-S since I do all the posting and all for him I figured why not is DSM forums instead of his forum (which he doesn't really post, only search and read). Well his car puts down 260whp @ 6.5 psi on slipping stock clutch.

Which should he get?

Since i've never had a slipping clutch I wouldn't know which one would be better. Thanks

Either looks good, just from glancing at them I notice the exedy is more expensive but has a sprung disk so street driving wont be an issue, but act has some good backing. Either looks good though

if he had the knowledge to build a 270hp honda, he should know what clutch to get.

I dont think that is true. Given the money I could go out and build a 500hp dsm but I would still ask people opinions on what clutch to run. I know what I would want to run but I'd like to get some feedback as to what people thought about the different clutches.
