I wouldn't recommend 'raising' the rear end to solve this issue, what happens when you have a full load of passengers, hit a dip, pull into or out of a steep driveway ect? Still gonna rub and eventually ruin the tire with any half-baked solution.

In my opinion a combination of negative camber and/or smaller tire is all that's left given that a light fender roll or correct offset wheels is out of the picture.

then, with that fitment, you will rub occasionally. No matter how much you raise the suspension, it will still articulate unless you lock it out.. At that point, you may as well have a cart.

Well the shock and the spring rate wouldn't be affected if I could find a spacer that would go between the top of the strut and the strut mount on the car. What would be the best tire size for minimal to no rubbing with my wheel specs? I prefer to have some sidewall and not completely stretched either.



Yuck

This is probably the most stretch I could bare.

don't under estimate the amount of camber the car gives when lowered. it actually has a LOT. i would not roll the fenders, i would trim or cut them since the metal is soo thick there that rolling will be difficult and cause waves.
"Donk-tastic".

It's quick and painless and works great. Though I gotta agree with PD and Timmy, even a shave like mine (PLEASE do not attempt to roll rear fenders) will not cure all fitment issues. It should be a well thought out approach starting with tire size. Having an adjustable set-up with coils or bags would help as well. Good luck.

After it is cut do you roll the edge? I might cut the inside lip like that as long as it's a straight cut.

I'm not going to. No need. I suppose you could cut then roll with the shorter edge. Every shop I talked to said these rear fender lips are too thick to attempt without causing damage. Up to you.

depends on a lot of things, like wheel offset, tire size, and ride height!

if you add a spacer the springs will increase in tension thus affecting spring rate and ride quality. you may try this product but they are mainly for spring sag.

One of our members made a spacer to bolt above the shock/strut mount. The bolts on the mount are usually sufficiently long to add about 1/4". I don't suggest this when there are other easier options like a fender shave or pull.
I've come the conclusion that I need a 2 inch thick spacer to put on the top of the strut. I need to figure out where I can find one and quick! If anyone knows where to find the spacers that fit on the top of the strut of this 94'...PLEASE POST A LINK.
