DCM-
Have you (or anybody else) actually checked to see what is the largest 48dp spur that will fit?
I know the 78t I run just fits, it looks like an 81 might be ok but I don't think there's any way an 84 will fit - which leaves you with only 2 spur options
I think ZX-5 spurs and pads
might be a better option, as they go down to a 76 (I think
) - just not sure of the hole diameter (no one wants to share that info
)
RE: the rear diff. Have I missed something here? The stock diffs on the car are steel aren't they
