I installed a zzp catted dn pipe, stage 1 sensors, and a trifecta tune, got big bump in power, but now the clutch is slipping, the car is a 09 HHR SS 20.l with the performance package and 71k on it, I have been researching clutches and have become more confused than ever on what I want and need. Trifecta says I should be about 330 torque. i use the car for daily driving, autox once a yr. no other racing, just need a clutch that will hold reliably for a daily street driver and not be harsh and expensive. I am looking for suggestions from people that have been there done that. and has worked without breaking the bank and works similar to stock feel.

 

May I suggest, you get a clutch that'll harness the power, or you'll be replacing the new one pretty quickly.
TTR's KY clutch is a good choice

I would make sure the clutch is the problem first. 70K seems awful quick for it to wear out. At least find out why the premature wear.

I am reminded how many people come here about transmission problems that turn out to be a cracked flex pipe.

 

my issue started after the tune, if I try to pass in 5th gear, and even 4th sometimes, you can hear the engine speed and rpm increase but no increase in speed. if I dont get on it. i have had no issue. i think I am just over powering the clutch, need one that will hold likely 400#'s of torque. i am not seeing any GM parts that will work for me. and not sure what will work and still keep reliability and be a good fit for the street.
