Clutch Masters stage 4/5 and you will be happy. Good all around clutches....I have had 4 friends with the stage 5's and 2 with the 4's and they both was awesome clutches and I think the 5's are guaranteed not to slip. I had good luck with competition clutches with my honda's and acura's but not with the srt-4 it wants to slip when it is not suppost to at my power level.
