Morning All
Ive just come across this web site and hoping you guys can help me out........
I have a Birkin Clubman which runs a Borg Warner M68 diff. It currently runs a 3.9 diff ratio which is way too high for my car.
Talking to a few people there are other diff ratios available with this diff a 4.11 and a 4.3.............whilst Ive heard of the 4.11 being available, I'm really looking for the 4.3 which would suit my car perfectly.
Is there such a ratio available and if so, can anyone point me the right direction to where I could find one??
Appreciate any help you can provide..............
Thanks
