Ridetech bump steer

[marolf101x]

You have yet to tell us your alignment settings. As more positive caster is added, the steering arm is lowered, which affects bumpsteer.
Just looking at your images the shims on the upper control arms appear to be about even (though difficult to tell). If correct, that means you don't have much caster in the alignment as it sits.
Let us know what you are running for alignment and we'll go from there.

We understand what bump steer is. You don't have championship winning cars without knowing a bit about basic suspension geometry.
I know that once you get under a certain number bumpsteer doesn't really matter as it doesn't really affect anything. This is determined in part by the tire you select.
I know the numbers you are stating are way off what we found during our testing and development of this product.
I also know the 1st Gen TruTurn was designed years ago before we started 3D scanning the cars and designing everything on the computer first. So data from that era is a bit difficult to come by. If we cannot find it in some notes somewhere it may not exist any longer. The newly developed parts have much better documentation and retention of those documents.
I know these cars are all a bit different. . .they were all slightly different the day they rolled off the assembly line, and in most cases haven't' gotten any better.

I also know we'll do about whatever it takes to get this figured out and make you happy. . .that's our job!
It is a little more difficult since you are not on the same continent as us, but we'll do what we can.
