as some of you know I'm getting my tranny in this week and when I took out my clutch to replace the clutch disc I noticed some heat spots on my flywheel. I'm using the Firdanza aluminum flywheel. Would it be beneficial to order the replacement surface disc for it? There are only like 3 heat spots and 2 of them aren't big and the other is a good size. I know hot spots aren't good but do I really need to change it?
