Hey Everyone.
I did a little searching the internet and this forum without success to my exact question. I could of missed it, but I figured I'll ask the experts!
A foxbody guy in Colorado needing some recommendations for setting bumpsteer. My first time doing all the alignment in my garage and could use some help.
I made all my own gauges to do the set-up since I'm too cheap to buy all the fancy tools from MM or elsewhere. Also I find it fun!
I've already done caster (checked camber at +20/-20 wheel turned) done camber ($10 level and bolts plus trigonometry) done toe (string around the car). And now on to bumpsteer...
The Car;
'88 Mustang, with SN95 control arms/spindles. Still using Fox steering rack and QA1 bumpsteer kit.
I've read a rule of thumb is to have less than .02" of toe change per inch of suspension travel, but toe change in what direction???
1. Should I have the toe travel go towards toe-in or toe-out during suspension compression?
2. Should I have the toe travel go towards toe-in or toe-out during suspension drop?
Overall I' going to try to shim the rod end to minimize toe travel but just don't know which way to bias the set-up.
Thanks for the help!
