Sure looks that way. I noticed that there were gouges in some of the rivet heads on the clutch disc and it looked like the friction material was sort of ‘flaking off’ around the rivet holes. I was very disappointed to see that when I pulled the disc off of the flywheel. I’ve got like $600 into even that clutch. Pressure plate side looks fine, strangely.
I don’t think I need to have custom friction discs made, either. The F23 transmission I use claims a 1" shaft with 14 splines. Tilton actually sell 14 spline discs on a 25mm shaft diameter. I know it doesn’t sound like much, but I was actually pretty worried about the .4mm difference. That’s 16 thousandths. Anyway, it turns out that the shaft isn’t actually 1" [25.4mm]. It’s pretty much spot on 25mm, so the discs should fit. I’m pretty sure I’m not the first to try and use this clutch in an F23, but I am the first to use this flywheel setup. Should help this little bastard rev even faster.
