Left rear quarter pannel rubs on the

tire basically anytime I am making a turn to the right - or even just slightly loading up that side - my mechanic says that a switch to a slightly larger or even much larger rear torsion bar will not solve that problem and that in order to eliminate this rubbing I may need to do much more -

My question is - what in the heck could be going on back there to allow the rub to occur.

Stock 23mm rear with a 3.0L motor - drivers side rear panel rub!!!!!

It is common for the left rear to rub and not the right, don't know why but the left is always the one, things to consider

are the lips rolled?
can you add more camber?

if both are maxed out, smaller tires or raise the ride height, both bummer solutions

I rolled my fender to stop this. Many have. Also, with all due respect to your mechanic, I know of 911's with sufficiently stiff suspensions that rubbing does not occur, even though the tire is visually, obviously, too wide. These suspensions are a bit too stiff for street use, though.

Hmm, so rolling the wheel well seems like it won't help as the point where it rubs - as evidenced by the little bubble of heated up and cracking paint, very small little mark - is 3 inches above the edge of the wheel well.

Stiffer rear suspension - I am planning on going from a 23mm to 25mm rear torsion bar and going with Bilstien sport shocks, also adjustable spring plate and stiff plastic bushings - right now the rear end is not "up" at all - my 911 is not set up with the rear end higher then front look - "indexed".... I just wonder if that 2mm rear torsion bar change + indexing is going to really do anything.... mu mechanic states that will not solve the rub problem - maybe it's really time for carrera flares.

Any thoughts or feedback is greatly appreciated!!!!!!!

I do need new tires and could go for a lower profile.

If your rear has 23mm bars and worn shocks, then I'd agree this is a significant upgrade for several reasons, including the rubbing problem. I'm not a big fan of plastic bushings. I hate to disagree with the pros and am probably all wet, but I'd expect a substantially stiffer rear suspension to help this problem considerably.

I don't remember whether it was Randy's white car or his blue one (probably the white one), but I once commented to a friend that the rear tires don't look like they fit into the wheel wells. They clearly bulge out past, and the car is low, so there is very little clearance. My friend said "Technically, they don't." I think Randy's rear bars are at least 30mm. Those tires are just not permitted into the wheel well. This remark and observation was made at an autocross event.

At some levels, I wonder why they don't just weld the spring plate to the car frame. (kidding, but you know what I mean)
