Replace your original M3 or Z3M sliding calipers by stiffer Wilwood’s SL4R units (4× 1.125” pistons) with the exact same piston area as the original calipers but bigger brake pads. You can also install SL4R calipers with larger 1.25” pistons for more rear bias.
Calipers p/n (4× 1.125” pistons) - 120-13234
Calipers p/n (4× 1.25” pistons) - 120-13233
Fits e36 M3 and Z3M.
Can also be fitted to non-M e36 / e46 if using e36 M3 or e46 M3 rotors. But it will lose the handbrake since non-M cars have Ø160mm handbrake drums and M cars have Ø180mm drums.
