@racecarmike posted:Donny, Have you checked by measurement to see if your car has excessive bump steer? I’m not far enough along on my car to check yet but I know from experience designing suspensions that steering arms being parallel to the ground doesn’t automatically equate to no bump steer. Maybe it does for P-cars at a specific ride height. It’s fairly easy to check and should be checked anyway.
The question has been asked before, "what is excessive bump steer"? We are looking for a number, not a description of what it is. Zero would be perfect but probably not possible, so what is an acceptable number?
I've looked as much as I can and there is no one that I know of that is quoting an actual number. They just speak in generalities.
IF someone is going to all of this work, and measuring bump steer is labor intensive, don't do it before shocks and springs, do it after.
There are a few race shops that deal in suspension components. Pegasus is just one of them and a good source, but Davids concern of using an adjusting nut instead of solid spacers is credible, but you can get the spacers separately also so you can use the Speedway studs, just plan on spacers as well.
I might suggest also that if you are going to go to this extent then get the sphere ball anti-sway bar ends and do them at the same time.
