3.9 FD...leave the 4.0 alone. If you plan on going FI, I wouldn't even bother with the FD. Most FI guys go from the stock 6spd (3.5) to the automatic FD (3.3). Makes 1st and 2nd on FI apps actually usable. lol.

JWT flywheel with an RPS Z32TT clutch. That would be a better choice. The JWT flywheel has a bolt pattern that fits both Z33 and Z32TT clutches. The advantage is the Z32TT clutches are bigger than the Z33 and hold a bit more. My single disc RPS is holding 532whp right now. My JWT clutch before that could barely hold 400.

Heard ok things about buddy club. alot of ppl use Tein. I used the HKS Hypermax IIIs...I'd ride in someones car first that has what you're looking for. Each company does it a little different. Hotchkis is right on
