So, 2/3 of the springs on my stock clutch broke, found one laying on the flywheel. Friction surfaces look almost new. There are pictures. Somewhat upset, but oh well. Time to upgrade.

South Bend sounds like my best option, but there's not a ton of info out there. Will probably call them, but would like to gather as much as possible from you guys first. I'm looking to put down a solid 300awhp, torque to match, with enough overhead to allow up to 350-400 (Unsure how far I'm going to take the car, and don't plan to buy or change more clutches than necessary) if that's possible. I do know that I'd prefer something with a full face disk, and a pedal throw similar to stock, ACT 2100, etc. Want something a bit tougher, but not so much that it will break my transmission, kill throwout bearings left and right, or cause my pedal assembly to notch out.

That said, the TZ Series looks about right. But I've also read that the DXD (and OFE, for that matter, though there's less info on it) has a fairly easy pedal throw and engages very smoothly as if it were a full face disk. Any advice or opinions on this would be appreciated.

Second thing is that I just plain out don't like the stock 20-pound flywheel. I wouldn't mind a slightly better throttle response, but don't want to have to keep on the accelerator to keep it from stalling. For example: I live on a hill (~25 degree grade) and there's a large dip in the road at the top. Hitting it at a speed above 10mph is pretty rough, so letting off the throttle just before is how I do it now. I don't want anything that could possibly allow RPMs to fall so fast that I'll stall there; that would be very bad.

Currently considering the ACT StreetLite and Fidanza's product. Whichever I go with, I want it to be completely plug-n-play. No nutty automatic plates, longer bolts, or whatever else. It will be driven under a multitude of conditions, so it needs to lend itself to a decent balance among them all. Straight line, twisties, city, hills, parking lots LOL, anything else I may have forgotten.

Help me out guys! Insight into any of the products I've mentioned, and similar products, will be highly appreciated. As will be info on where to get the best deals on everything.

Thanks in advance for all the help, and all the non-TL;DR replies! :D
 
Fidanza flywheels rock. XTD stage 3 is pretty nice too. Been rocking on for 3 years now and I dont have one of those freakishly large left legs
 
I prefer the ACT streetlite flywheel with the SBC clutch.
 
Sorry to zombie this thread, but I don't want to start a new one on the same subject.

I recently received my new South Bend TZ clutch (2200lb PP and Kevlar disk). Is it okay to run this clutch with the stock flywheel? Is there anything special that needs to be done such as step height? Will the stocker hold up to the heat these clutches can produce? My flywheel was recently resurfaced (1k miles ago) by my machinist and the step height was taken down exactly equal to how much was milled off the flywheel surface. There was no clutch failure or anything so it's still in good shape.

I would much rather use the stock flywheel for "driveability" and because it's so freshly resurfaced I'd hate to have wasted that time and money. But if it's an absolutely horrible idea I'll gladly get an ACT streetlight or something along those lines.

Your stock flywheel will be just fine if the step is right.

So your saying if the step is still stock spec I should be good? Maybe I'll have it double check for assurance. Thanks for the reply!
 
Just picking this up but was just wondering what the outcome you had was WES. Looking to run my Southbend Disk with the stock flywheel aslo.
 
It works just fine with the stock Flywheel. 0.608"-0.612" step height. If you are running the full Kevlar TZ-series disk I recommend having your machinist media blast the friction surface with 80-120-grit aluminum oxide blast media after machining flat to help with Kevlar break in process.
