I'd recommend the Road Magnets over oem mz3, oem msp3 (on a mz3), Prokits, or Stechs. The ride is absolutely amazing. If you are looking for performance these are the springs for you. Choose your ride height (1.25 or 1.75) to suit your ride height needs and zoom zoom. These springs are hands down the best spring rates you can get for our cars without going to coils.
