I think you'll be pleased with the Spec Stage 2 and Heavyweight billet steel SMF setup.

So far, I've tried Amsoil Synchromesh manual transmission fluid, and and Castrol TWS Motorsport 10W-60, and I can't say that I hear any difference between the two with respect to gear rattle.

If your gear oil has been in the car for over 20k miles, it would probably be a good idea to change it, but it may not matter as far as gear rattle is concerned.

Live well,
