how is this even possible ? (4th gen rear and lowering springs)

ok so after blowing up my rear end i replaced it with a disk rear out of a 97 TA, and i put eiback springs in.... other then that everything else is stock in the rear (lca's, panhard, yada yada yada) so the rear end SHOULD stick out the drivers side if anything.... but somehow its sticking out the pass side....

i havnt moved the car yet since taking it off the jackstands, so im HOPING that it goes back to normal once i drive it, but what could cause this to happen ?

When the suspendion moves up or down the panhard bar will move the rear end side to side...

go for a dig, maybe its just sitting weird, but my guess is you'll have to buy an adjustable bar.


Like you said, it should have gone out the drivers side. sticking out the passenger side would indicate a lift...

If your old springs were sagging that bad, then an Eibach Pro Kit might have actually raised the rear. The Pro Kit only lowers 1/2 inch from stock - it's quite possible that the old springs sagged well over that much. My stock springs are sagging terribly, and I just got the Pro Kit, hoping it would raise back up some, or at least stay where it's at without bottoming out like it does now.

Regardless, I got an adjustable panhard bar anyway - my stock bar seems to have a bend in it - my pass rear quarter panel also has a crunch in it, so I'm assuming this prior rear hit bent the panhard rod in mine. Edlebrock 5222 bar only $109.

I know, another $100 bux! I feel the pain - I just dropped $825 for the Eibach's and Bilsteins all around. But you might as well spend it - can't take it with you!

Its not quite 2" is it?


Anyways thats beside the point, he has a problem with it being offset which is caused by either a foobared panhard bar or a lift/lower in the suspension height.

The entire rear is actually almost almost 4 inches longer - which makes almost 2 inches sticking out farther on each side.

Sorry - didn't know they were Sportlines - you do need an adjustable panhard rod with Sportlines from what I read, since they drop over 1 inch in rear.

Thre best I can tell you is to get an adjustable panhard bar and see what happens. You need one anyway so youmight as well buy it now and install it and see what you can get out of it. if the problem persist then let me know. I did this swap on my car and my rear stuck out the drivers side a little bit. I am running 315/37/17's and its not as bad as yours is.
Also, take your wheels off and get under your car with a tape measure and start measuring distances on the rear to the frame. See if the rear is aligned straight from front to rear. check your LCAs and see if their straight. Do the springs look plum when the car is resting on the ground?

Here's a thought - do you have the 16 inch wheels? If so, the 16 inch wheels are not interchangable between the front and rear - maybe you have a front wheel on the rear, and a rear wheel on the front - a front wheel on the rear will stick out farther!

The wheels themselves will be stamped with "front" and "rear". Check that and see.

Also, if you try to drive with a rear wheel on the front, it will rub against the tie rod ends, and the ear on the strut, scraping the rim and removing any wheel weights you have on the inner lip (ask me how I know ).
