12 Bolt upgrade
It is time to upgrade my 12 bolt rearend.
I do many street miles, always driving to/from the track, cruising and so on.
Chevelle Ė69 3860lbs raceready.
Transbrake 4000rpm and front wheels will see a little bit of air.
Best ET 10.63 127mph so far.
My goal is to go high 9:s, but not faster in this car.
Rearend have steel bearing caps, Eaton clutch plate posi and stock 30 spline axles with c-clip eliminators today.
I have to change the axles to better quality, but will 30 splines with c-clipeliminators and my posi be enough?
