My M Roadster's braking system needed a refresh, but instead of just replacing the pads, I decided to completely overhaul the calipers, install new rotors and pads and then flush the system. The M Roadster's stock braking system is more than ample for the car, but my car was fitted with stainless steel brake lines which reduce the sponginess of the stock rubber lines and help give the system a little more bite.

The suspension system of the Z3 M Roadster is fairly straightforward, using Macpherson struts in the front and a trailing arm system used in the rear that was first used in the 3-series cars back in the 1980s. The BMW Motorsport Group did make a number of meaningful upgrades to the suspension of the M cars vs the standard Z3s by installing stronger components, similar to parts found on the e36 M3. You can see the enhancements from subtle differences like where the front swaybar links connect to the strut housing instead of the control arm.
