These spring plates are essentially an exact copy of the Porsche OEM spring plates from 1978-1989.  Height adjustable with eccentric bolts.  Set includes (4) HD rubber rear bushings.  They have a nicely marked gradient scale to eliminate the guess work and avoid marking them up with an ink marker.  Available for G50 cars as well.
*Please note that when converting to coil overs, adjustable (for ride height) spring plates are not necessary.
 
*For a significant upgrade this spring plate set is 100% compatible with our Rebel S Racing Rear Bushing Set.
