I have a 2007 with square 245s and a CR front sway bar, everything else is OEM. I am looking to further increase the front roll stiffness, and am considering lower ball joint spacers.

1. Does anyone make a simple roll center adjuster/spacer without an offset ball joint? I am not interested in running more aggressive static camber, as my car is 100% street driven. Also I would like to stay with the OEM ball joints and as many other OEM parts as possible.

2. I assume that spacing up the lower ball joint would also effect the bump steer, since it would effectively lower the car the same distance as the spacer thickness. Would a small steering rack spacer be beneficial? Am I diving too far into this and making an issue where there isn't one?

3. Instead of the spacers (or in addition), could I install an offset upper control arm bushings with the hole towards the bottom? This should have about half the effect as the LBJ spacer, but without the bump steer change. Does anyone have any experience with these (do they slip under heavy load)?

Incorrect assumption if you are to use the rca as intended, which is to re adjust your ride hight via aftermarket coilover after installation, otherwise if you just install the rca all you are doing is lowering the ride height without changing the lower control arm positioning and not doing anything for the roll center. What changes the roll center is the position of the lower control arm. So for example you have a lowered car you want to increase roll center on, you will install the Rca which will lower the car further but from the hub, and then you want to raise the coilover the same amount as the rca shim to keep same ride hieght as before but now with the altered lower control arm geometry.

So given that, bump steer/toe would not be effected.
