Coilover Parts-911 Springs (Perches) For Bilstein Struts (Front) 1965-89
Extended Length Front Strut upper perches
Coilover springs increase the diameter of front struts, often contacting the chassis such that the spring diameter limits the available camber adjustment range.
These extended-length upper spring perches solve the problem by moving the spring down where it won't contact the chassis.
Some cars can get over a degree of added camber adjustment range.
They also act as a dust cover to help keep the wiper seal clean and long-lived.
Extended-length perches are available for 2.25" springs. You can add a 2.25" to 2.5" adaptor to use with 2.5" springs.
Available with a 26mm ID for use only with Quick Change camber plates and with a 16mm ID for use with conventional camber plates
