I'm about to take the front suspension apart to replace it from the cross bar forward. While doing that I would like to change the front brakes. I'm interested in reducing the unsprung weight and the reciprocating mass. I have on hand Brembo calipers but they are for vented rotors. They do have a spacer but my question is can I remove the spacer to make fit early rotors. Also, do I have to change out the hubs to get early type rotors. I have had the calipers on the car before but they over powered the rears. This is an A/X only car and I believe that the brakes will never get hot.
I currently have everything but the rotors and shocks and I believe that my friends at PMB or Tangerine Racing have the knowledge.

All of these changes should bring the car weight down to under 1600 pounds.
