    Any benefits to NO shock on front of LR?

    Is it better forward drive with shock on front of LR? Or two shocks on LR?

    LR = Shock/spring on the rear = most bite, Shock/spring on rear dummy on front = is less drive. Shock and spring in front = least amount of drive.

      Ego, with just one shock on the LR behind with spring and nothing on front of birdcage, what valving and gas pressure shock?

          I have added a "traction shock" to the LR front w/a 5-3 gas shock in the back and picked up a throttle push. So, in my recent experience, a high compression, low rebound shock in front=more traction.

            The front shock will provide more damping than the rear shock.
            The front shock will also help the driver keep the car on the bars on a track where you have to get all the way out of the gas.
            A front dummy shock(w/spring behind) is nothing but a hike limiter. (I don't care what Joe's book says!

                Does anyone run a dummy shock behind with spring and "real" shock in front? I am thinking of trying this, but what would be good valving and gas pressure for front shock?

                  Most 4 bar mods run that setup. Spring slider behind and a 9-2 or 7-3 in front.

                    Joe's book is a guide not a bible haha, I don't swear by it. I listened to your advice last race and it served me well .

                    I currently have a 8c 2r behind my LR and nothing in front. Going from a fixed 4 valve to this shock tightened the car up on the throttle alot. I will run this set up for at least a few races before I try moving the shock locations. I have a few other things to change first.

                    Most handling problems can be solved by adjusting the screw-ball. It can be difficult to fine tune at times. Explaining yourself loudly and striking it on top of the helmet with a dead blow hammer usually works well.

                      What if the traction shock is mounted on a clamp bracket?

                        I'd be conservative on valving going w/a gas shock in the front, maybe in the 5-2 or 6-2 w/around 100PSI of nitrogen. Lates have a lot more tire on the ground than a mod.
                        Depends on the track/and/or condition too(wet & heavy vs. dry & slick). Off or on the gas on entry.....driver feel.....etc....

                          More compression in a clamped front shock would take traction away as it would resist compression with pinion wrap. I think...

                            Putting the front shock on a clamp type mount gives body lift with pinion wrap.....extra kick in the ass , when its needed.
                            Now what if you put a spring on there too?

                              SSSHhhhhhh That is a secret!!!! HAHA! Kinda like a clamp on both sides in front with shock and springs on both along with shocks and springs on the birdcages.
