I had my first run with my TC4. I wanted to have a spare car to my TC5.
I was only about 0.5 sec slower. So far so good.
I melted my rear diff. I had spare steel outdrives but the diff rings don't
fit due to the "D"-form of the rings. I hope you guys understand what i mean.
The shop on the track had rings from the NTC3 but they don't fit due to the
smaller dia. I ended up dremeling the rings to make them fit.
Surprisingly it worked. Does someone know the item# for the rings?
And also the # of the plastic part where the 2-56 locknut comes in?
(because there is no hex in the steel outdrives)
Thanks for your help...
