I have heard of guys with other cars claiming going up on the spring can make the car cut more, if not steer more. Seems like this is with the old school front end more...?

I also went to more caster (shims back), heavier spring (copper, them SM black), 7000 wt instead of 5000wt trying to get the car to get thru the middle of the turn and finish the corner better. Going to a Dbl. Pink / gray combo helped the most. I have noticed that I want more mid/exit steering on a consistent basis...any ideas? I'm trying to get this thing sorted for the Halloween Classic, and i'm going to the local track tomorrow, so fire away

Thanks

RobK,

Have you tried white rears? Try white rears with double pink fronts on 20 front springs. You may need to go back to the copper center spring. One thing to watch out for with whites is traction going away late in the run.

Hi Jeff,

I don't claim credit for coming up with this solution - one of my racing buddies showed me this.

Basically, you trim the fiberglass backing plate flush with the motor end-bell. Then, bend the tabs backwards and trim them to proper length.

I've attached a pic.

What did you do to your motor to make the body sit lower. Did you trim the tabs? Any chance you can post a pic. I'm trying to lower the body on my DB12R without having the body hit the motor tabs.

Thanks,

Jeff

Hey rob,

Try running the pod .5mm tilt with the front of the pod being .5mm lower than the rear of the pod and then set your uptravel over ride height to 1mm. What this will do is give you less pod lift or antisquat under acceleration and do away with some of the push you are getting. At the same time it will still allow you your 1mm uptravel to help absorb the bumps. This gives more overall steering from my experience. Let me know how it goes.
