Leigh what is the diff rings difference in weights? one looks much thinner than the other
and see why the ae86 japs run alloy plates with thicker rings machined down to save weight
Any weight over the rear end must be a good thing with these cars...
With my R180, the weight distribution was 52/48 front to rear.
Stick an R200 and a full tank of fuel and 50/50 may be there!
