Don't they do the same thing? If you remove the 90-10, what other changes should be made? How do 6th coil adjustments affect the car. I tried removing the 90-10, but the car didn't seem to respond to the brakes at all. Couldn't get it to set up.

i played with the axle damper a little bit when we couldn't seem to free our car up enough entering the turns, particularly on tacky, momentum type tracks. in the end, under the advice from rocket we took it off, and have never put it back on.

changing the angle of the 9/1 shock down at the frame (front) seems to loosen the car and angling it more upwards seems to tighten.
also moving it left to right seems to make a difference, but i could never quite pinpoint what it was exactly.
the rocket guys told me that you only really need a 9/1 when you want to really tighten the car up entering the corner under brakes.
again sdhnc29, go24 or 2nd2none may have some more experience with this.

Taking the 90/10 out seems to "quicken" up the suspension as well as free the chassis going into the corner. If your running lr behind and clamped, take the 90/10 out! The braking force will now go throughb the 6th coil but use a 400lb spring in it and it'll work fine. That should be all the changes that you have to make, I'm wondering if you don't have a bind somewhere BUT more info would be helpful ie...."Couldn't get it to set up".

Left rear is behind on a dummy with the shock in front- not clamped. Without the 90-10, the car did not respond any differently no matter how much bias. It seemed much tighter all the time, even with rf brake shut off.

what shock are you running on the 5th coil? You can run a 3/7 shock which will help to keep that torque arm from slamming down onto the 6th spring.

I don't believe thge 90/10 on/off is your problem, it's more than likley in your bar angles or percentages. Send us your set-up & one of us can try to give ya a hand. Incidently the only time I run a dummy shock is when it's tacky, it comes off when it slicks over.
7300 shock w/a 300 spring is a good baseline for the 5th arm.

I'm running a 7300 shock on the 5th coil, bar angles are 20 lu, 5ll, 22 ru, 0 rl. 500lf/75, 400rf/76, 250lr/94, 225lr/94. LR coil is on dummy behind, 21.5" J bar 8" up on frame, bottom/2nd hole up on pinion.

Brakes are clamped only. Nothing else.

Make sure you dont have the brake lines going to the wrong master cyclinder. we had the same problem for the first three nights before we realized what the problem was.
