If the TOB is not pressing against the fingers on the clutch correctly, it could ruin the clutch. My friend put a centerforce stage 4 in his mustang gt but the TOB wasn't on right and wasted his 600 bucks or something like that that he spent on it. Word to the wise, make sure the TOB is on the clutch forks correctly. Check that the sleeves on the TOB is on both fingers of the fork. I almost missed this on my friends miata. Good thing i caught it while doing final checks on everything.
