I have been going to a different track for the past three weeks and the track is extremely slick. Other people that race there say it is the slickest track they'be ever run on. It is a 3/8 mile track and has very little banking. The problem I'm having is I have no forward bite! The car does not roll or lift. I have raised the ride heights 3/4" all the way around the car, I have 650 springs in front straight across, have 200 left rear, 150 right rear. Shocks are: left front-74, right front- 76-3, left rear-93, right rear- 93. Biscuit type pull bar. 25 degrees down , 90/10 damper, 5 degrees up, left rear trailing arm. 15" center, 15 degree up. Right rear same length, 10 degree up. 60% rear, 51.3% left side, 125 lb split. Springs are on top of rear-end. I can drive the car anywhere I want on the track and the car doesn't push or feel lose, just no forward bite. Any help would be greatly appreciated.

P.S. I have a DW7!

What kind of panhard bar are you running, front or rear mount, how long, what angle. Remember all of your links are the geometry of the car, be sure nothing is bound up. Sounds like you got a pretty good setup, but I would put a 75 shock on the lf and a 750 lb spring on the rf.

t/10 next time you go to the track remove the 90/10 shock from the top of the rear end. LEAVE IT OFF...... a biscut pull bar doesn't need a shock, and it only creates a bind.........there is something holding the rear of the car up........in the garage you can bounce on the car then disconnect something and bounce again......keep doing this until you feel the car bounce easy...then you have found the problem with not getting weight transfer........I say it's that 90/10 shock is bent

Hey Awkwardjeff, does that taking the 90/10 shock off work on a swingarm car as well? It is a lightning chassis, true swingarm with z link and a bisquit pullbar. I race on a pretty fast 4/10 mile track that is extremely dryslick. Main problem is a skating rear end of car that starts with braking. Just wordering about the 90/10 deal.

Thanks

Thanks awkwardjeff I will try it this weekend. Will there be anything radical that I should be aware of until I get used to it.

rf shock has to much compression for a dry slick track.
decrease pull bar angle to 15 deg.
lower rr trailing arm to 5 deg.
