89 s13 hatch, coils,toe arms,camber arms.

So i noticed today the my rear passenger tires sticks out from my qauter panel by about an inch and a half, and my driver side is in by about a half of an inch.... I have the same offset wheels(zero) on both sides, i checked, and same tires.. Can i adjust the subframe to fix this? I know this is an easy fix with a solid rear axle. Pretty much i dunno how to adjust thrust angle on my car.

That doesn't mean your thrust angle is off, thrust angle would be if both wheels pointed right 2* or something, then the car would not drive straight. On a live rear axle car, the tires are always pointing in the same direction in relation to each other, and you change the alignment of the live rear in relation to the car... independent rear suspension has separate toe adjustments for each wheel.

A lot of cars have bodywork/subframes/etc that make the wheels stick out different amounts, which you wouldn't notice on stock wheel fitment, but its very noticeable when you put bigger wheels on there.

There's no adjustment for the wheels/axles/etc for what you're talking about, better to roll the fenders so it looks even on both sides.

If you put a pillow under her ass you'll get better thrust angle.

Seriously though, the right side track on these cars sticks out more. Ikeya Formula and SPL Parts make an adjustable LCA where you can narrow the track but it's expensive:

Hahahahahahaha. So true!

But yeah, about the cars, just do a baseball bat roll or whatever and they'll look the same.

There's no adjustment in the subframe. You could experiment with an aftermarket adjustable lower a-arm, but It's probably easier to get one wheel spacer.

Do you have subframe collars? If you haven't ever hit anything and are pretty sure your subframe isn't actually kinked, then it could be that your subframe bushings are shot enough to have allowed the subframe to shift a bit.

Also take a closer look at the body lines, it could merely be that it's been smacked in the past and the bodywork isn't 100%.

Im running a real weak neg camber right now so that dosnt help.. I know some cars have asymmetrical suspension. So 240s are supposed to be like that? Cuz i cant stands it it looks fucking dumb.

GSXRJJordan · 11-04-2008, 02:50 PM

Yes, they're all like that, as Norm and I said. Take out the negative camber, because that looks stupid in the rear, and roll your fenders a little bit. They'll look the same after that.
