Sorry, I don't have the exact incremental change at the tip of fingers, but you can figure out the general affect by looking at current angle of the steering tie rods. Since the steering rack is behind the king pin if the steering rod droops downward or are level (from chassis to upright) then raising the car will cause more toe-out. If the current angle is slanting upward, then raising the car will cause more toe-in (up the point where the steering arms are level).Hi,
If I raise the front coilovers ~1/2 inch on both sides and leave everything else untouched, will this action result in an incremental toe-in or toe-out on a Lotus Elise?
You might want to just max it out, then maybe move a washer on one side if it pulls.Holy cow. Everything was soooo out of whack. Even my caster was, and still is, way off. Long story short, after 5 hours, we called it a day (1/2 of it spent setting the height and corner weighting). I realized just looking at the car and the wheel gap give false perception of a positive rake. What looked like a 10mm+ rake actually turned out to be only ~2mm rake. Can a competent mechanic use strings to accurately measure caster?
Jay,According to that diagram and the picture you provided (and my recollection of my car), all the shims/washers are on the front mounting point of the upper control arm (and the rear mounting point is basically "floating" w/ no resistance from washers front or behind). Is this a correct observation on my part? Also, if I want to increase my caster, do I move the shims/washers to the front or rear of the mounting point?
