Trying to figure out if I can safely go 1" per side to make the front track the same as the rear....I currently have 1.25" thick spacers, so I could eliminate those which would be nice.
I figure not that big of a deal on the camber since that is easily fixed by opening up the top of the shock tower (salvage title car, so no worries about "ruining it" (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) ) For those that have installed turbo-tie rods, do you think there is enough adjustment to move the ends out an inch per side???

JP, good illustration (figuratively). I agree with you that the same sweep angle creates a larger arc with a larger scrub radius.... which is why I believe scrub radius can increase the required steering wheel torque/efforts.
Where I disagree is in how is effects the car. Let's discuss.... As you change the steering wheel angle scrub radius matters (increased efforts, larger arc by the wheel for a given steering wheel angle), no question. But, if you're at a fixed steering wheel angle, does the scrub radius matter? It shouldn't, unless compliances are in the equation. Hmmmmm, I think I've talked myself into believing that positive scrub radius can cause the front tires to skid, but only as your changing the steering wheel angle. I do think it makes sense that the faster you go the smaller this problem because the tire patch refreshes more quickly. |
