Got those too. Changing that will actually make the car pull to one side all the way down the track. Very dangerous!
I had my car scaled and know exactly what it likes to make the wieght even from side to side. But, at the track, it didn't like the same thing.
A dedicated rear sway bar with travel limiters in the front control arms will get rid of 99% of what is happening. A good 12 point cage will do the rest.
You tell 'em I'm comin' and Hell's comin' with me, ya hear? Hell's comin' with me!
