    Rf spring location

    What affect has anyone he moving the rf spring in or out at lower control. Single spring rule deal thanks

    Moving in makes wheel rate softer and make control arm more likely to bend.

        Yes, it's just like putting a softer spring in the outside hole.

          Could you run a little bit stiffer rate spring by moving it in to get drive back since can’t run bumps or stacks

            Also would it benift by moving the upper mount down some to increase roll with stiffer spring without having to do it by lead

              Moving the mount down does not do anything. You can play with a arm mount location and spring rate all you want. Any combo that gives the same wheel rate is the same.

              If you need to defeat the no bump rule, use spring rubber if allowed.

              If not, I'd disconnect the upper coilover mount from the upper rail, hide a torsional spring inside, attach the mount to the torsional spring, preload it to the proper load where your spring binds, and use it for suspension. Seal the gaps with silicone and paint. It will look welded to an unsuspecting tech guy.

                    You would essentially be on a stacked rf setup yielding a softer initial rate and then when your coil over hit coil bind the shock mount would continue to hinge on a torsion bar giving you additional travel aswell as a progressive spring curve. And if the mount were positioned correctly you might even gain some balljoint to shock body clearance.

                      How the heck do you mount the torsion on the frame
