If you don't travel the same you not only are losing load but your bars aren't travelling the same. So if you travel 1" or whatever on a stiff spring then all the sudden the track slows and you travel 1/2 you have lost load as well as the roll steer and thrust angle are different. So you'll see these spring rubber setups pull rubbers because all though the spring is softer you won't lose as much load because you gain the travel back to 1" and keep the other variables constant. Talking with another forum member here they don't travel 3" to be fast they are a different amount but I think the goal is the same to maintain the same variables.
    Thanks. Unfortunately we can't run spring rubbers.

      That's Insane I guess they would rather you get another shock valved identical with another spring setup on it in the smasher to change to or take the smasher to the track and change it or do all it of and know your turn differences for the spring change ahead of time

        So whats trump? Thrust angles and bar angles or travel numbers?

        Meaning, the track slicks off and your travel is decreasing from the 3 inches you want to maintain. You can either go lighter spring and have less load at 3 inches or go less travel with the heavier

        I guess it would be travel, maintaining the travel numbers with spring changes.

        Just say no...

            Take compression out of the RR shock when it gets slick. Possibly take rounds out of both rights sides and add to both left sides to give the car some "pre-tilt".

              Yep....and practice what Mark Bush has been preaching for awhile.....decrease left side weight!
              Turn LEFT, Vote RIGHT!

                so how much decrease left side we talking most chassis builders want you around 54 or so.

                  Not something I'd do, but like everything not right or wrong just my personal opinion

I'm like 7up what is to high of load number for dryslick conditions. thanks for all help.
                    Are you high static load with a medium spring or low static load with a stiff spring? big difference...

                    Meaning if you are saying a load at 2.5" of 1000# are you:

                    1. 375# static with a 250
                    2. 187.5 static with a 325

                    ^ I just made up so numbers that was easy^

                    Second group of questions:

                    1. Does it have side bite sometimes and other times it don't - meaning inconstant
                    2. Are you pinching the car, trying to diamond? paper clip or momentum type track
                    3. Have side bite for a while then loses it
                    A. If so, does it recover real slowly

                      my rr right now is a 250 without me in its 11 1/4 tall from 12 inch tall spring so sure my static number isn’t high

                        Wanna feel the rr better in the slick? Raise the jbar or drop the lf out a little more.

                        Tilting the car works well and taking compression out of the right sides helps

                        The guy i have been running with has taught me a lot about balance and that changing the balance of the car can and will be detrimental.

                          He says 53.5-54.

                          I say....do whatever the car/driver likes. Its just a number.

                          Me personaly....I have always had good luck with shortening the rs bars 1/4-3/4 inch. We had a blue Rocket one time, and the driver felt shortening the bars 1/2" tightened the car up the best. I asked Josh Richards and he said that was a common adj for those type cars.

                            You want your car to have the same attitude in the slick as it does in traction. How you do that varies depending on type of track and preferred line on the track.
