Some of that is what engineers call tram lining--wider tires and IRS
exacerbate the problem and there's no real solution other than skinny
tires and solid axles. My Ferrari does it, and so does my Radical. The
bushings probably won't help much unless you have induced toe because of
flex in the rubber mounts. Then it might help a bit, but probably won't
cure the problem.

Here's a handling question for i.r.s. guys......
When crossing grooves caused by heavy vehicles the i.r.s. cars do a weird
"snake hips" sort of wiggle, due to toe change at the rear wheels I
suppose. I have only noticed this in street driving, possibly tracks are
smoother, but I cannot imagine it helps lap times or predictability. Other
than changing to polyurethane bushings is there any other solution, and
will the bushings eliminate or just reduce this?
Simon..TR4A with i.r.s.
