Hello guys, allow me to introduce myself. I have been lurking around here for awhile, and I finally decided to join.
I have a 1992 240sx coupe that i am swapping a vq35HR and a few other 350z parts into... i'll probably start a thread here on that some time, but until then, heres a link: http://my350z.com/forum/engine-and-d...s13-240sx.html
anyways, I always hear that when you lower a 240sx, you need to correct the bumpsteer. ive seen the outer tie rod ends that allow you to space the outer pivot downwards, and i get how that works, but i was wondering what we are actually looking for on our cars as far as bumpsteer.
say i have 1/16th" of toe-in up front.... when the wheels hit a bump that compresses them 3 inches, what would we want the toe to be then? what about when the wheels droop an inch or two? Im looking for a theoretical answer, more than say, "you should drop the outer end one inch..."
i realize that there is no magical answer, but you may assume that i have a slightly lowered car, stiff springs, and i like to go fast.
on a somewhat related note, how do you guys feel about the akermann in our cars? if you could hypothetically change it, would you increase it, decrease it, leave it? why?
the reason i ask is that i moved my steering rack down 2 inches to fit my engine in, and i am planning to compensate by moving the outer pivot points on knuckles... with either long studs or welded extensions. i need to know what to aim for as far as geometry goes.
thanks
