How much lower are you setting the front. With the correct diameter tires, the front fender is ~27" +/- 1/4" (or so).
As long as the car isn't lowered more than ~3/4", then you can "eye ball" the bumpsteer so that on flat level ground, setting the tire rod as MM says in their instructions gets you pretty damn close!
As you go past ~1" drop, bumpsteer will be
always an issue (unless you have ~$5-$10K+ in
suspension mods). However, again, setting the tie rod set as MM says is "pretty good". It'll be better than if you left it alone. However, because of the Fox
suspension, tolerances, different choices in stuff, there's more variability in the spacers needed for the least bumpsteer effect. And,
as I understand, there's also less of an absolute clear choice between 'what the best setting is".
In reality, very few shops know how to measure bumpsteer, will measure bumpsteer, or will set bumpsteer. And, for those of use that do not have a nice flat level perfect concrete surface to measure/set our bumpsteer on (use the MM tools!), then just setting the tie rods as MM suggests for "eye balling it" is "pretty good".
For AutoX handling, to get the best bumpsteer setting, then I'd suggest finding a shop, or begging to use a friend's garage for a few hours (offer to change their oil, and pay for the oil and filter of their choice
), or try to find a rent-a-bay, etc.
