I am looking into the possibility of replacing my stock clutch with something aftermarket, and I need some advice.

I was just going to get an ACT street clutch, but then I heard some people say they get a lot of clutch chatter with them. What I need is something of better quality than the crap Nissan clutch that came with the car, but at the same time I want a stronger more durable clutch that will stand up to some ocasional aggresive driving. Keep in mind that driveablity is key since I have a commute.

Also would it be in my best interest to change to a lightweight flywheel in the process? Or would I be sacrificing driveability?

Any advice would be great!

thanks
