So I've owned this car for 3 years since 100,000.

Car drives fine and straight and from looking at like never been in a frame accident.

Problem. Front suspension. One side maxes camber out at 2.3 while the other side will do 3.2. I have Megan offset camber ball joints.

I am only able to max out my caster around 5.3 or so

Not sure if it's worth testing the arm or if it's possibly the subframe slightly off.

Any suggestions?

 

Check your subframe alignment holes and torque the subframe bolts while you're under there. If the subframe needs alignment loosen the big bolts and use a punch to move the frame to align both front holes.

 

How much play do you think is there?

 

Not sure how much play is there but lots of people seem to have found a few of them loose. If 1/16" of toe makes a difference in steering feel a little misalignment of the frame will have an impact for sure

Move the subframe....

 

There might not be any 'play' but the subframe might have shifted when hitting a pothole or other high stress event.

See the bottom of my alignment page for more info: S2000 Alignment


Here's the shop manual page showing the subframe bolts and alignment holes:

 

I know my front bolts were slightly loose

Has anyone tried to move the sub frame?

How much effort is required to shift it over?

I ask because the sub frame does hold the engine which should be 500 pounds or so

I asked my alignment guy to try and he was hesitant and told me to do it myself and bring it so he can check.

 

You loosen all the subframe bolts a few turns then use a metal punch that is just slightly thinner than the holes and use the punch as a lever to move the subframe around. You can use a rubber mallet to help with the movement. Make sure both holes are aligned then torque up the bolts.

 

I think I'll try this. I have a digital level that I can put on the wheel and see if this increases or decreases camber

 

Is it possible to have installed the camber joint backwards? Even if the subframe is shifted to one side it will only be about .3 to .5 off from side to side not a whole degree. Perhaps something might be bent like spindle or control arm
