105 steering arm position - bumpsteer

Hans-Peter · #1 (**permalink**) 03-04-2009, 03:56 PM

On my 105 track car I have installed RJR dropped spindles and different springs to get the bottom A arms sitting horizontal -- Richard supplied some matching arms which are very nice but they didn't have enough drop so we have installed the standard arms swaped over and upside down, this means that the ball joints now sit on top of the arm. The tie rods are now in right place to minimise bumpsteer . I can't see any problems with this but I've been wrong before -- any comments

yes actually. I do have a comment. If you have the lower ball joint upside down, and the spindle is in the normal position, the ball joints spindle will not seat well in the upright hole. If I am saying this correctly.
It will not seat, because the hole is conical!
So, explain!

Maybe I didn't explain myself properly - both the steering arm and the tie rod ball joint are upside down from standard so it seats perfectly - just like from teh factory. I was wondering if there might be any other effects. Have driven the car today on the track and it drives fine .

This guy on the BB has done a similar thing (swapping the steering arms left-to-right and flipping them) to sort out bumpsteer, although it was done along with a rack & pinion conversion.

Seems like a perfectly legitimate thing to do.
