if i upgrade my clutch to a better clutch.. will it still slip if i leave my 1st hard? if i did upgrade, wat would be the best clutch yo get for my car.?

 

aftermarket clutch don't slip as much but all in all it depends on your driving style. the only reason you're slipping the stock clutch is because a) you're shifting to early b) you're engine is revving high but you're car isn't moving at the maximum speed for a shift at that high rpm. if you honestly want to waste money on an aftermarket clutch instead of adjusting your driving style that's all on you.

as for the best aftermarket clutch that all depends on who you talk to.
search the forum, there was a poll taken.

 

The Clutchmaster stage 3 and 4 or very good kits for Cobalts. The stock clutches can't take the abuse an aftermarket will.
