Method for cutting a rebound spring for those who want to do it.
Removal of the original set up of the front suspension.
Assembly of the front suspension without the rebound spring.
Car on the ground, bounce the car several times to get the balance position. The car sits only on the main spring.
I guess it would be better to do it before replacing the kingpins in order to have less friction.
Measure the free part of the kingpin along the lower part of the kingpin : gap between the hub stub bottom and the lug plate.
Cut the rebound spring at this size.
An estimated calculation for my PLUS 4 with original 110 lb/inch main spring :
intitial length of the rebound spring : 90 mm
final length of cutted rebound spring : ~44 mm
Roughly the half length and twice of stiffness for rebound spring + 110 lb/inch of main spring during rebound.
No problem with the sizes, but difficult to know with precision the stiffness of the main spring.
I am not queen of cutting a spring as explained previously. Having the SSL kit, I don’t have this concern.
