I am putting on ford racing spring , mm caster camber plates, new struts, mm strut tower brace..Already have mm weld in subframes, k member brace. Dont know much about bumpsteer kits.. Should I invest in it? anything else I should look at replaceing like ball joints?
If you're not changing the K-member or the spindles or the balljoint design, or slamming it to the ground, you don't need a bumpsteer kit and could do more harm than good if you didn't set it up right.
If you replace them with stock, you shouldn't need a kit. If you go with Steeda X2's, you should install and properly adjust a bumpsteer kit, because they change the geometric relationship between the control arm and the tie rod.
