Mitsubishi Evolution VIII / IX Final Drive Gear Test

Tomioka Racing Mitsubishi Evolution VIII / IX Final Drive Gear Test @ English Racing

My thoughts on the Tomioka Racing 4.0 final drive for Evos VII thru IX 5-speed transmissions.

So a few months back we had a Tomioka rep stop by and give me a final drive to try which I thought was way cool of them. The best car I felt to try it in that we had was my 2.4 FPHTA green car since it was a low rpm high TQ motor. As far as install it went great. Had to reshim the intermediate shaft some. The factory shim was .042 and I had to move it to a .036 which for a totally different shaft is great tolerance I think.
