Could realy use some opinions on a way to get more forward drive. I realy need it when the track starts to slicken off. It feels like the car gets through the corner ok, but it realy layed over on the right side coming off. The left rear is hiked way up with the right front pinned the whole time. Just lose all my forward traction once the car is straight. I just put on the bsb 20 series shock package a couple nights ago. Left rear is a realy stiff with a ton of gas and the right front is realy soft with a ton of rebound. I know these are things that you want with a slick track, but my question is, can you get to much hike in the left rear that will actually take away forward drive? Im open to any options you guys have. Thanks a lot!

Did the car do this before putting that shock pkg on?
Is this an underslung car or overrail? How much lr drop do you have if its an overrail? How much pull bar angle? How much jbar rake? I would raise the lrt bar up a hole or 2 on frame to see if that helps the drive off, if you've already tried that, you might try dropping the lrt bar on b/c toward axle if you have the holes in it. If your rules allow, you might try a straight panhard bar to left side of pinion. Good luck.

Make sure your shock has the right amount of drop for the left rear. You may need a 2'' ex. on the left rear shock.

tire pressures are
lf 12

pull bar is all the way to the left on frame and 1" to the right on the rear end.

also, the chain stops just before the shock tops out. will try to get j and bar pull bar angles, anything else tomorrow. thanks for the help. realy appreciate any thoughts!

also, what will I see dropping the left rear top bar on the birdcage rather than raising it on the frame?

Reacts quicker
Have you tried having the pull bar centered on rear end or to the left some?
Have you tried squaring up the rear end, no lead or trail?
Check lr drop if its an overrail. Just some suggestions and good luck.

Go down to the thread titled Traction From Apex, it is about 24 threads below yours. There are numerous suggestions that you can look at. Good Luck.
