M-Coupe Rear end

[Andy325i]

Hi guys, does anyone know the difference between an E30 and M-Coupe Rear end suspension?

Can someone fill in the blanks?

M Coupe:

Uprated Diff? E30/E36 or different mounts just for the M-Coupe? Ratio?

Same/Different rear subframe as an E30?

I know the arms have reinforcement in them (A)

What gives an M-Coupe a wider rear track than the E30? is the spacing of the arms on the rear subframe or the arms themselves?


just found out:
The ///M:
Rear Track is 58.7 inchs what is an E30?
rear discs are 12.3 x 0.8-inchs


Many thanks

Andy
