Will an adjustable upper control arm square up my rear?

Hi guys. I’m new to the forum and still figuring out how to post. I was told by the previous owners body man that a adjustable upper control arm will square up the rear as it should be. It’s a salvage 04 Targa Top. 40,000. I have pics of ore-rebuild that I’ll be posting once I get familiar with the forum.

I would be interested to know if anyone makes something like that for our cars

Mark, are you talking about drivability or looks. If you are talking about drivability, take it to an alignment shop. Could be just a couple of turns on your tie rods.

Sorry, I’m new to the forum and just realized how stupid that sounded. Obviously had I said to the guy, if the frame is not bent like you say, why not just get a factory control arm.... didn’t want to call the guy out. After all it was t my car yet.

Definetly drivability. No sense in getting the mods I want if the car isn’t as safe as it should be. It had a front end alignment just before I picked it up. I wasn’t impressed

Find a good frame shop in your area and have them check it out. The will let you know if there is a frame problem, suspension component problem, etc. It could just be your have -1.5 rear camber that is causing that gap. On my autocross C5 I run -1.2 rear camber with 0 toe and have little to no uneveness in wear or ride comfort. (The fronts have -2.2 camber and 0 toe with 7.4 caster). Even with extreme alignment it still rides very well driving to events around the state.

1. get the frame checked this is an absolute must..
2 before you go, take a look at the upper control arm bushings to see if they have "rocked forward" somewhat .... this is usually more of a problem with the front end of the cars but can happen with the rears.... enclosed is a video from LG motorsports that shows how much "walk" the rubber bushings have over their solid (road race only) bushings.

Let's slow down here a little. I do believe that all C5s have an offset in the rear tires that are not symmetrical. I would do a little research on some known good cars before I panicked too much. I can check my wheel spacing out when I get home, but I can assure you they are not equal on both sides.
