| Not sure if you are trying to fit this to your M3 but H&R does not make a cup kit for the E46 M3. They do it for the standard non-M3 E46s which lowers cars with the Sport Package .75" Front and .25" rear. If the car does not have sport, then it lowers the car 1.4" Front and .75" Rear.
These will run firmer than your standard suspension in either the Sport or Touring version.
We have all the specs up on our site for you as well: H&R Cup Kit for the E46
