Can anyone recommend anywhere South Manchester/Cheshire able to work on a BTR Limited Slip Diff. Just needs a seal change but my locals aren't keen to touch it (or don't have the requisite four pillar ramp).
Bit further away, but still the NW, give Grinspeed Motorsport a call. He’s always working with diffs and gearboxes (mainly Honda though), but he is ex M-Sport and knows what’s what.
