I've been itching to replace the 25-year-old coilovers on the M3 with something modern and... not blown. My friends at H&R built a complete custom setup for the M3, and I wanted to take the opportunity to put together the ultimate how-to for assembly and disassembly.
The process is the same for any classic BMW.
The new H&R coilovers include camber plates, adjustable dampers, and aluminum RSMs, just to name a few details. The installation was as easy as could be, too. I'm really eager to get out and run the M3 again ASAP at Buttonwillow or Chuckwalla Valley Raceway.
