I have 2 with V diffs both autos originally eunos spec, one i converted and its a tight wee diff,other i know its working but on an auto not much needed …the guy who is MR.LS Diff for MX5’s works maybe 3 miles from me…I Spoke with him at length last year and he asked me about my stuff , if youre rallying forget about that torsen diff he said it doesnt work when wheels are in the air…So ok on a track but bumpy lanes and rough stuff its no bloody use , his words , not mine…will
I think a rebuilt/upgraded Fuji diff is the best clubman rally option from the standard diffs. My intention is to try with that and upgrade only if it feels inadequate.
