The passenger side front wheel on my car sticks out about a half an inch farther than the driver's wheel. The car is aligned and drives straight as an arrow though. Maybe an accident with a previous owner could have caused it, but I don't know. All I want to know is what should I check for and if and how I can go about fixing it. The car is riding on the stock 16" Z28 wheels. Thanks for any and all help.

 

when i put my ZR1's on, i found very narrow spacers underneath the stock wheels....maybe you have just one spacer sitting behind one of your wheels?

 

Sounds like you have 3 fronts and 1 rear, or vice-versa; instead of 2 and 2.

The offset difference between Fs and Rs is about .4" or so.

 

The stock spacers were for the rears only and wouldn't have made the wheel/tire stick out a 1/2 inch. My 85 IROC's wheels are marked "front" and "rear." Could be Sofa's on the money.

Nope. The 2 front wheels are on the front and the 2 rears are on the rear.

 

Then maybe your fenders aren't hung straight.

The car chassis is the thing you measure against. You don't make the chassis fit the sheet metal, you dress the sheet metal to the chassis. As we all know, factory fit & finish isn't always perfect, and even if the car hasn't been wrecked, things shift over the course of a lifetime of bumps and vibration.

Also, alignment will change where the wheels sit; and the 2 sides of the car aren't supposed to be aligned quite exactly the same. So even if you trammed the entire car and got the frame perfectly straight and the fenders perfectly symmetrical to the frame, the wheel gaps might still be slightly different from side to side.

Try exchanging the L & R wheels and see what happens.
