South bends, stage 4, street disc review

xsamis

Long story short, my engine went out, i was going to build it and figured that just putting a used one in for now was my best option, i also figured that hey while they're dropping the engine he can do my clutch for me too, so it was clutch hunting time, did a little research and the conclusion was the southbends stage 4 with the DXD flywheel and the quiet disc due to the fact of im boosting my car

Now to the good stuff, the clutch isnt on yet, its getting ordered, but Joe at Z speed, is (to put in good terms) the man. The guy knows everything and breezed through all my questions with no hesitation lol, so ontop of the clutch kit im getting the CMAK csc eliminator kit, will update on how everything goes and how the clutch performs, weather its too stiff, good, great, the noise, witch is a big one for alot of you guys. See you in a week

Awesome, I always enjoy reading those kind of product reviews! I'm running the SouthBend Stage 3 with lw flywheel and quiet disk option + CMAK, very similar to your setup. It's a good clutch, though definitely more noisy than stock at low RPMs (fine for me, bothers the wife a little bit). Has a very good bite to it, grabs and clamps exactly the way I want it to. Way more firm than stock, but very streetable IMO.

lol the noise was a big issue for me but im going to find out how big of a difference it is, btw offtopic but the g37 engine and 370z engine are the same exact thing right? or am i loosing my mind?

Currently running cmak version one and southbend stage 4 with quiet disk and southbend flywheel. Clutch was awesome at first but after 30k it started squeaking when pedal is depressed and at 40k throw out bearing is starting to make noise with the pedal down. Looks like the V2 has a better throwout bearing set up though so hopefully you have better luck then me lol

UPDATE:::

So i just got a new engine in my car, it wss a used g37 engine and its working flawlessly, the clutch i still have jn the break in period, but so far its super responsive, i have the quiet disc, and if you decide to get this clutch make sure you get it, i hear rattle when im at low rps, and its noticable, kinda sounds like a tractor, when i start moving it goes away, so it doesnt really bother me, my whole concern was the noise while at a light, witch this has 0, the only problem ive had with it, is i had to replace a starter, and a starter replacement takes 30 minutes, with the CMAk in the way (it bolts on the starter bolt and covers the bolt) it took probably double the time, super annoying lol, but other then that it works really well, had to bleed the clutch because of air in the system, and have no issues with it so far, revmatch is making my break in really smooth and flawless, make sure you have it on, the pedal feel is tougher to push in, but its a street/race clutch so thats a given, in heavy traffic it does make my clutch leg tired, but once you free up, its worth every penny, super fast engadgement, and very fsst reponse, to be honast, i dont notice that crazy of a difference with the 19 lb flywheel, alot of people swear by it but i cant tell that much of a difference, my mechanic did tell me he prefers the single mass, because you can reserface them and this DXD has alot of meat on it so its resurfacable mulitple times, all in all would i change looking back? No, im going to be boosted in the future BUT even not being boosted i like it alot, so far, we will see in a couple thousand miles
