Do you have a link / details of the uprated driveshafts please.

Mine are due for replacement and I was considering whether it's worth putting in uprated ones.

Thanks

Simon
I'll dig out the details Simon.

A reworked T5 is not going to defy physics, the gears and shafts are still very small compared to a TKO600, and there is no way around this, each component/tooth is still under lots more load, due to surface area even if it is made of unobtainium.
A Tremec 6 speed will compromise your exhaust size/clearance, personally if i were you its a TKO600 with a 3.08 diff..

Why dont you have a drive of mine and get a feel for the box/ratios?

I have no idea on the plate or bell housing as i have an LS so did not research Rover option, sorry..
The Crown wheel i got from John Reid at Grantura Engineering, however you can get them from Australia Ebay for cheap money but they are a slightly smaller CW although the same gearing, and therefore not as strong, i have broke one of these!
