Default My car is sitting wrong....

I wasnt sure where to post this but here it is! The passenger side of my car is sitting a good 2 inches lower than the drivers side for some reason. The passenger side has always sat just a hair lower but now its incredibly noticable!! The suspension setup is stock springs, QA1 shocks, no front sway back, BMR Drag Bar in rear, Adjustable PHR, LCAs. I checked the gap between the coils on the front springs when the car was on the ground and it was equal on both sides. The upper a-arm on the passenger side was just about closed and the drivers side was open a good bit! The fender gap on the passenger is very small and the drivers side is huge! What in the world could be going on here? This has just happened recently I believe.

I highly doubt the body is twisted any sort of way because before I even raced the car, I put subframe connectors on it and since it ran low 13s its always had a roll bar setup in it! Once it hit low 12s high high 11s we upgraded from the 4pt roll bar to the 8pt roll bar.

Any ideas?

i can only adjust the spring height in the front. that doesnt solve the problem in the rear. Also the springs in the front are at the same spot on both shocks.

Does one spring have the isolator on the top and one doesnt?

It sounds like you have the rear Drag Bar set-up wrong.
The best way to set-up your car is with scales.
If no scales are available I would do the following;
Disconnect the rear Drag bar.
Adjust both front Hal springs to the same coil position.
Put the car on the ground and have someone sit in the car with about the same weight as you.
Measure both rear well measurement. They should be close to equal.
I would then turn the front driver coil about ½ tighter to raise the drive front and this will add weight to the passenger rear tire. If you had a scale you would want about 15lbs more lbs. on the passenger rear as compared to the driver rear with you sitting in it. To accomplish this you adjust the front coil adjuster.
Now, last adjust and hook up the rear Drag Bar without any preload with you sitting in it.

This made my car sit square, sixty better and launch straight.

Heres what we think the problem is....I had some guys at the local shop look at the car today and we think we know what the problem is:
the rear passenger side spring is compressed about 1 3/4" more than the drivers side when the car is sittin on the ground.

I guess I should replace those factory springs now...
What springs should I get? Do you want a stiff spring in the rear or a soft spring? what about the front?

Disconnect your drag bar and I bet it will sit straight
