I think I've ready about a dozen threads relating to bump steer.
I see the issue and it's easily remedied by the aftermarket parts available. Rear bump steer or "passive rear steer" as Honda called it in the CRX doesn't really worry me. What I'm noticing in all the images I see of lowered front suspensions is the angle of the lower control arm and the comments about lack of ride quality. If you look at a pic of a stock height suspension, the arm sits at about a 20 degree angle downwards (estimated). If you look at a lowered car the angle is usually less than 10 degrees or even parallel with the ground. (eek!) I know we have a few racers / engineers here on the forum, has anyone calculated the roll center of the car stock / lowered? Has anyone tried an extended lower ball joint? I've seen de-cambered but not extended. I'm curious to see what you guys think. |

there is an exhaustive technical discussion of this in several articles in Circle Track magazine of a few yrs ago
it is worth finding & reading or just google "roll center" |
