RIde height

Though not running Campys, I'm running 295/15 in the back as well. No rubbing issues at all...

What kind of measurements would you like to have?

315s in the rear without rubbing. The 255s in the front on the other hand......

There are at least two different series of 10"Campys but to my knowlege they all have the same mounting dimensions. Panteras are well known for slowly collapsing the rear body structure; spot-welds slowly shear over time and things begin to move. A clue is if the rear tires have excess camber or if someone has added adjustable upper rear a-arms to compensate for the slow collapse.
Another thing that occasionally happens is a wrecked car is made into whats called a 'splitter'- parts of two (or more) cars welded together- inexpertly- to produce an externally good looking Pantera that forever has handling issues. Clues on these often have non-factory subframe einforcements under the floor.
Your car can be set up on a chassis jig and checked for out-of alignment areas, then corrected to factory specs, usually by welding. Monococques do not correct easily; be prepared. An experienced Pantera-specialty shop or even a cadre of old-time owners may be able to point out whatever problems are producing your tire rub. Good luck.

You need to put the car on a lift and examine the suspension. If it all checks out correctly (which I doubt that it does right now) then it needs to go on an alignment machine.

What BossWrench says is all true, but is really a very rare scenario.

(I don't aim this at you personally Nybs. The following is just a generalized statement that unfortunately find is more and more true.)

This is all presuming that you knew something about what you were looking at when you bought the car and have some mechanical aptitude to begin with.

I am still flabbergasted by the quantity of people who buy these cars that are border line between recognizing them as a Camaro, or something more unique then that.

I had one guy come to me bitchin' about the car, paying all of this money and the people who built it were retards. Then I find out he bought it off of someones front lawn after it sat in the mud for 25 years and he paid $6,500 for it?

Common'. Give us some kind of credit for having some kind of intelligent consciousness? You need to know at least it isn't a Camaro? Knowing that Monococque is a type of chassis and isn't a porn star helps a lot too.

I know what you are saying, I have been a Pantera fan since I rode it one when I was 16 which I don't want to admit how long ago that was. I actually have a lift in my garage, if there is frame damage from a previous accident I can't see it. The only damage to the car when I bought it was the lower valance on the front was mildly crunched from curb impact. I guess I will take it in and see what a frame shop says. The car actually drives great and with the shocks adjusted the wheel rub is gone. The issue I have is the shocks should not be that far out of adjustment on each corner, so what gives. Its the kind of thing that most people would not care about but for some reason it bothers me.

A 305-50-15 should fit on the 10" Campi with no rubbing issues.

Look for a spacer between the wheel and wheel hub.

What kind of shocks are these? They would seem like the most likely suspect to me.

Quality control hs gone to Hell on this stuff.

Get on the phone with the Manufacturers tech people (Aldin?) Let them tell you what is wrong with the shocks.

Who was the vendor you bought them from. Most here are VERY knowledgeable and Very helpful and have experiences with these products on their own Panteras.

Gerry,

You may have several different spring rates, instead of two different rates (one rate for the front, and another rate for the rear).

You might have the right rear and the right front swapped. Check the wire diameter of the springs with a dial or digital caliper. The larger diameter should be in the rear, and the smaller diameter in the front.

The shocks themselves are the same front and rear. Be aware that at least some Vendors sell shocks that are shorter in overall length than the original shock. You may have gotten different length shocks.

Let us know what you find.
