I'm pretty sure my 7" 90-10 braking shock is bottoming out (compression) on entry and making the car loose on dry slick conditions. I'm considering removing the shock, but not sure what to expect, or if anyone has other solutions. The car has about 7-8 degrees of pinion angle, running the monte bar, j-bar, and 4 link on both sides.

try moving your mount on the axle housing.we did that a few years ago, but then we took the shock off all together.we use a spring bar now.

Don't be afraid to try taking the shock off. It will loosen you up on entry some, but it's better than having a bind. Most guys I think will use it as a tuning tool for dry slick to help tighten up on entry, you may just have to look at your rear end bracket. Did DW jig the rear end or did you? Are you sure you have the right bracket?

If you take it out how are you going to finish races when your pull bar breaks? Seriously, I think you should cut the mount and move it so it bottom outs under acceleration. That way you won't have any forward bite and I can pass you easier.
Actually if your shock is bottoming out under braking it shouldn't make you that loose as long as it is still running uphill to the chasis. Remember the bumpers I used to run on mine before they outlawed them? While those had a little give, they tightened the car on entry. Can you move your 90/10 to the right or raise it on the front mount?

Our Dw car does the same thing with a Bilstein, but with an afco I think its fine. The removeable ends just take up a little more space. WE started running a rubber bumper on ours to try to keep it from just crashing down and bottoming out.

You might give the 10/90 shock a try,we use to use this on the DW cars until we started floating the brakes.

Thanks for the responses. First, the bracket was jigged by DW. The problem is most apparent during dryslick conditions. Also, I am running an AFCO braking shock.

Aggressive, when you mention the 10-90 shock are you suggesting 10- compression and 90- rebound??? Won't that effect/hurt the forward bite by the high rebound valving???

JWS- I'll see you this weekend!

A 90/10 is 90 out 10 in.A 10/90 is 10 out 90 in,now if u don't want to run the 4bar without a shock this is a good alternative,the 90 in seems to really take the slam down effect out non floated brakes.

Actually i think you have it backwards. The first number is compression and the second is extension. An afco 90/10 is 90 in 10 out. I thin k most shocks are this way except bilsteins i beleive are the opposite.

Thanks for all the posts. I ran without the braking shock last Saturday. Track was extremely heavy (put on +30 tear-offs). Car was stable on braking and turned into the corner really good. Didn't seem to notice any detrimental effects of removing the shock. I'll have to see the results on a very slick track. Probably have to wait until open shows at the end of the season.
