I have read a ton of threads and i am still not sure what clutch to get for my LSJ. The Spec 2 clutch went out on it(not sure if it was spec 2+). I didint even know it had that clutch until the shop pulled it out and showed me. I have read some good things about the spec 2+ clutches as well as the execy stage 2 and gmpp one as well. Currently my mods are TVS, 60's with option b, header and zzp catback and Trifecta Tune. I also installed a phenolic spacer. Future mods will be meth injection and zzp stealth heat exchanger. Just wondering what clutch would be best for this setup. I am leaning towards buying the gmpp with another flywheel since this is the cheaper route. THe stage 2+ is about 600 alone. Thoughts or suggestions?

 

If you go with any, the GMPP is a nice clutch as I ran it and it held up to over 400whp. Stay away from Spec clutches. If you do not get a GMPP clutch, go to zzperformance.com and buy their Southbend series clutch, can't go wrong! Also if you don't get the GMPP and you do get a Southbend, make sure you buy a new clutch pipe and the upgraded TOB.

 

GMPP/thread

 

What he said GMPP or Southbend /thread

 

Gmpp.

 

Since hes asking, does anyone know the max hp anyone has ever pushed a GMPP clutch?

 

I have no idea, but I might test this with the 4.45 and my build when it's finished since it will be a daily.

 

The GMPP is way underestimated. I never had one slippage when I had over 400whp. I wonder if it would hold 550whp.

 

Yeah, the GMPP is pretty robust. You can floor it in 2nd, dump the clutch, and it'll just spin the tires. The stock clutch would slip so bad if you did that, lol.

 

Well I'm going for 600+whp so it would be the ultimate test lol but if it means my trans will last longer then sweet. I don't go to the strip that much anyways, mostly in the street.

 

I agree GMPP or Southbend.

 

I had a Southbend stage 3 in my ZZP stage 3 car. Worked tremendously. Never let me down.

How I miss my old car

 

Does anyone know who's running the most power with the gmpp? We know it's fine with 4xxwhp, but anyone beyond that power level?

 

I have the ZZP/South Bend stage 4 on my LNF. Great clutch! Just got done breaking it in last week!

 

Curious to know this as well. Clutch depends on the torque though.

 

Well I imagine I'm going to have around 5xx-6xxwtq lol

 

Kenny/ zrated was running high 500's with it far as I know

 

The GMPP??

 

Yep almost positive. Extended time at that power level it wouldn't last I'd bet

 

Yea probably depends how you drive and how often you go to the strip

 

Big boy power haha

 

More like $10k power hahaha

 

Went ahead and got the gmpp clutch kit as well as the flywheel.

 

Did you get a new clutch pipe and fly wheel bolts? How much did everything run you?

 

Go fast or go broke trying
