Im trying to figure out the best route to handle this. Unfortunately after a long few months of some trans work I finally got my brz on the road for some tuning. Right off the bat i got what appears to be a terribly loud bearing noise. Tore the diff apart and the side bearings are fine but haven’t gotten to the pinion bearing yet. I wanna take this opportunity to get a higher gear ratio since im supercharged also the cd009 transmission gears feel short. Who sells good quality ring & pinions with a 3.58 or 3.73 ratio? Ive contacted weir weeks ago with no response and been hunting for a m85 diff from a is300 with no success.
