Default Front Suspension is Not Making Sense





Checkout the images above. Yes the front end is off the ground but even when on the ground the passenger front looks to be sticking out further or doesn't have as much negative camber as the drivers side does. I was messing with the adjusters on the passenger side to get it to look like the drivers side to no avail (don't worry I'm getting an alignment tomorrow and will let you know what they find out). The car does pull to the right but I know the toe is pointing outwards on the passenger side so that's what's causing that.

I made sure the passenger side caster bolt matched the drivers side to see if that helped, it didn't, so then checking the camber bolt it was already maxxed out to negative camber, rotating it would have added positive camber pointing the top of the wheel away from the car. Which is weird because the drivers front, which looks like it's got 1-2° of negative camber has it's bolt pointing on the inside of the car, meaning it's at it's adjustment point with the least amount of camber...

What I'd like are any suggestions to correct this just in case the alignment shop isn't able to get it trued up? Could a control arm be bent? Does the subframe need loosened then adjusted a little bit to one side? There's no evidence of accident damage, there's no outline around bolts that would make me think things shifted, so it's kind of baffling.

I'm paranoid this is a major issue but really hope it's not, thanks.

The car has been aligned, but still I see the passenger front tire sticking out passed the fender.
So I have some proof of what I'm talking about.
These measurements were taken with the car in the air, but the front suspension was loaded.

Drivers Front/Front measurement ~12" to tie rod end
Passenger Front/Front measurement ~12.25" to tie rod end (depending on where we're looking, but verifiable to be sticking out further.
Drivers Front/Rear measurement ~11.875 to brake caliper
Passenger Front/Rear Measurement ~12.4375 to brake caliper (again sticking out further)

So this is proof the passenger side is sticking out further. Now can anyone pinpoint me in the right direction?

Are you sure the adjustment bolts moves freely and that you are not just turning the bushings?
It's not to uncommon with loose subframe bolts, so check that first and also check that it's centered.
There's reference holes in the body and subframe on both sides that you can use as a guide, they are located close to the most rearward bolts.

From the photos, it looks more to me like the passenger side isn't so much sticking out as rather just turned to the right (turned as if making a right hand turn).

You said the right was toe out. I think thats all this is. If you pointed the steering wheel perfectly straight and didn't move it from one photo to the other, than I say its just toe.

If you want to make sure, point the passenger side tire perfectly straight ahead, and redo the photos (without moving steering wheel) I bet now its the drivers side that looks sticked out.

Front end alignment measurements would sure help. IME, hard to eye-ball anything accurately.

Yes, when adjusting the bolts I could tell it was moving the control arm and not just spinning freely. I will look for those and also ask the shop to keep an eye out for that as well.

I thought that, and was hoping that, but when I rotated the wheel so that it was aiming perfectly straight it was still dead obvious that it was sticking out. Perhaps, and hopefully, adjusting toe will change that but I don't see how, here's for hoping.

True and I wanted to get some opinions first but after my alignment tomorrow I'll post the results.

Updated first post with some suspension measurements. Someone help me figure out what's wrong. Do I need to take it to a different alignment shop to figure this out? I got it aligned at Tireman but they didn't notice anything different from one side to the other.

Not knowing what is wrong is keeping me from spending money on this car, the sooner I can figure this out the sooner I can get to modding more!

I would echo checking the subframe and add checking the steering rack. You are correct, that isn't right.

OK just found this thread so I'll definitely check for loose bolts and subframe alignment tomorrow, this makes a lot of sense because the car will feel like it's darting from one side of the lane to the other so this is probably what's wrong

Nope, front subframe is aligned and all of the bolts are tight, so that's not it. Should the upper arm ball joints be the same? One side has stamped EM25 and the other side is stamped EM24, does that mean anything?

Taking it to a body shop today to discuss inspecting the frame and making sure everything is in its proper location, so until I get that squared away here's some more information to rack your brain.
I had these coilovers on my previous S2000, so the heights were already setup and everything. Well after throwing them on this car I went to adjust the height to make it perfect again and the right front (the one with the issue) had to be adjust .5625" just to get it the same height as the front left. That's far too much of a discrepancy between sides.

And here's a couple more pictures to confuse.

Front Right


Front Left



Its plain to see the upper arm is not at the same angle on both sides, this is with both sides of the suspension loaded up.
