What backspacing are you running on those wheels? Stock width rear end?

 

I run a 275/35/18, 3" drop 68 Camaro no rubbing.

 

69 wheel lips do not roll easily. Usually a trim at the 10 and 2 o'clock positions is all that is needed depending on ride height.

I have the same size wheles/tires. Did exactly what Don said. I used an air recip body saw and trimmed that section (10 - 2) back about 1/4" on the pass side only, just shy of the spotwelds. Did the same to the wheelwell trim on that side. Never a rub on the outside. Occasional rubs on the inside if going into a steep driveway cut at an angle - I don't worry about it

 

Chris, I had the same issue on my '69 with 275/40/17 on a 9.5 inch torq thurst with 5.5 backspacing and DSE 3" drop rear springs. I did not want to trim the fender, so I bought 255/45/17 and so far, so good. The 275/40/17 do look better.

 

I have a '68 and I rolled the lips on that. It was a huge PITA and doesn't work as easily as you would think and my wheel lips are round. Couldn't even imagine what a mess it would be to try it on a '69 with the flat. And I did it before bodywork. If your car is painted and looks good, do NOT try to roll the lips - too much can go wrong with that scenario.

 

You could also try using a die grinder to remove some of the outer lip metal as suggested at the 10 and 2 positions. It would take a bit longer than a saw, but you can remove a lot of material with one of those pretty quickly and with a bit more control than you might have with a saw, just a thought. As for the inner, I'd roll back toward the centerline of the car (with a hammer) any seam edges that could catch on the tire if it rubs so if it does rub it is rubbing on a smooth surface and not one that catches or cuts the tire. A thin spacer would help, but would further aggravate the outer rubbnng which can do more damage to the tire than an inner rub.

 

The rear wheels are 17x9.5 with a 5.5 backspace and +6mm offset. The Moser rear end was ordered to stock length.
Trimming the fenders sounds like the best choice even though we had already purchased a fender roller.* Since this car has relatively new paint we're terrified about risking cracking or blistering the paint while rolling. And the roller instructions state that it's not to be used for double wall seams anyway.
We gave Hotchkis a call about the issue and they said the 17x9.5 is pushing it on a stock setup. They like to run 9" if not tubed.* So their advice was to trim also. (BTW, our Camaro has Hotchkis leafs and our TransAm has the DSE leafs).
And looking up from below the tire, it looks as if only the rear of the fender needs to be trimmed. See photo arrows. Not sure about what you guys mean about trimming the 10 o'clock position.
* 2 o'clock looks like it's only giving me trouble since that's where the fender starts to taper back toward the rear end. (unless I'm reading the clock wrong.)
The fender scraped the tire a bit but some of the rub mark can be removed.

 

after posting that picture of the rear end we noticed a missing nut on the right side shock. went back out to the car and not only was it missing but the left side was almost about to remove itself as well. no idea how these came loose with a lock washer on both(?) we are now using locking nuts AND blue lock . Maybe just maybe that is why we had the rubbing issue ;^) we'll take it out for a test drive and let you know later

 

Chris, did you move forward with rolling the quarter lips, or were you able to avoid this? I'm searching on this same subject, trying to fit a 30x9" slick in '69 wheel wells.

 

we got out the grinder and removed about .25'' of the fender lip. that took it to the edge of the spot welds leaving the welds intact. that's all we needed on the outboard side of the tire, no more rubbing issue. Now, the real problem is the inboard side of the tire rubbing against the tub. (see pic) . this only occurs when going up or down a steep driveway no matter how drastic of an angle we approach at. we may look into an 18x9 in the rear, unless there are other suggestions.:frown2:

 

I have a fender roller and it works fine on a 69 Rear Fender

 

 

Could you post a pic of the ride height?

Try approaching the driveway straight on so both wheels move up the same distance at the same time.

Don

 

sometimes its not possible to approach straight.
and here's some pics of the stance

 

 

WOW!
its 3 years later and i forgot to mention how i fixed this problem for good... i stretched the metal at the inner fender well with a rivet gun and a flat 1-1/2'' rivet set. I merely massaged the problem area and then resprayed the undercoating! Works perfect now. only needed about 1/4'' more room and gave it about 1/2'' more room. looks perfect and I don't have to grit my teeth and close my eyes every time we go up/down a steep driveway . I have since put about 2000 miles on the car with no issues.

 

That sounds great though. Good to know that you were able to make it work.
