I'm going to get an ATB differential from Quaife.
What is the procedure?
Do you just order one and take it to a garage to fit, or do specialists fit them?
If it is specialists (and I hope so) then does anyone know of one in the NW of England?
(I was tempted by RR's comments over the last few months and it seems to work so well in the new RS, plus my BMW has a normal LSD and I like it.)
Thanks
