I know there are shops out there that raise the spindle on bilstein struts then heat and bend the steering knuckle down to help with bump steer. I plan on lowering the front suspension about 1.5" by using the adjuster. I have boge struts and want to know if anyone has done just the heating and bending of the steering knuckle, does it work to counteract bump steer, is it hard to do acurately?

QUOTE On a lowered car, you want to get your A-Arms as close to parallel to the ground as possible. Hmmmmmmm... that would mean that Fig. 2 is OK because the a-arms are quite parallel to the ground. Also... what if I didn't want to lower it that much; would that be wrong? A parallel a-arm is not making sense. I'm sticking with the tie-rods parallel to the ground and the rack. because in Fig. 1 and Fig. 3+4 that's the constant. Fig. 1 shows a tie-rod that is correct and parallel. Fig. 3+4 shows a tie-rod that is supposedly correct and parallel. Me thinks you've been drink'n again. (IMG:style_emoticons/default/w00t.gif) |
