. I think different people have different needs. My need is just to get rid of that sharp edge. It barely touches the tire when the suspension bottoms out.
I had a similar issue due to suspension sag and a blown front shock. I just bought the $15 ride height adjustment tool and it hasn't been an issue since
You should have no problem achieving your goal with that tool. I first started using that tool many years ago and that led to the 928OC adopting it as one of their first loaner tools.
A couple of tips that are very important.
First and foremost, prep, prep, prep. Be sure to clean completely any undercoating, crud, dirt, etc, that will inevitability be jammed and hidden on the backside of the fender lip. Clean, scrape, etc to get the areas behind the fold completely smooth. Otherwise you will end up with unsightly bulges and uneven spots and will increase the likelihood of paint cracking.
Due to the shape " unround" shape of the rear fender do not attempt to do full sweeps of the tool as you would with a more symmetrical fender opening shape. Start at the top of the "flat" area of the rear fender and adjust the tool so that it will sweep that area without loosing contact of the actual roller on the fender. Start slow and work it back and forth and move the new contour towards the front and back of that flat area first. It will then be easier to readjust the tool to sweep the more curved sections on the sides of the opening (if needed)
Take your time, make sure you have a good heat gun to keep that paint warm, and make double sure you have cleaned out behind the fold!!
Hope that helps.

I just put my chrome cruising rims and tires on. The tires are Sumitomo. Although the were the same numeric size as my BF Goodrich G-Force at 245-50-16 (which cleared by less than 1/4inch) and are on the same stock staggered rim, in the most extreme left turn caused the slightest of rubbing. My 84 has factory spacers and extended rear studs. I, being aware of the risk of point over stressing the paint on the steel qurters, folded up some layers of heavy cardboard (the width of the tire) and wedged it between the tire and fender before bouncing the car to clearance the tire.
Just a 2 cents worth if one does not need too much room.
Just looked at the video and have to chime that putting wheels on the car that wouldnt allow the full travel of the suspension does not seem prudent. I would think that 1) you can loose control if the car gets out of equilibrium by crunching a fender in a turn
2) you would obviously damage the car
3) you would not be able to utilize the car within its design parameters (drive at the design limit).
It might just be the reflection in the paint, but the fender looks like it comes down normally and then near the opening flips out, which looks a bit odd if that's how it looks in person. With the fender roller, you should be able to reshape the whole fender so the whole thing is gradually moved out.
I used the Eastwood Fender Roller tool on the front fenders of my 928 Spyder and it worked well to tuck the sharp lip up inside. No contact since.
I just posted a message to the fender rolling thread on the 928 OC tool loaner forum. Im looking forward to gaining a few mm's out back. Rolled the fenders on my 79 911 20+ years ago with a bat & some heat, & it went well. no unsightly wrinkles or paint cracking.
Thanks for the posts. All this info is super helpful!
I'll let you know how it goes.

Sumitomo? My prayers are with you - even though I'm not religious. I was driving one day on an uneven surface and the 928 was all over the place. I was so surprised by the erratic movement that I had to stop and check if one of the wheel was lose. To cut the story short, it was the soft sidewall of the Sumitomo that was wrecking the drivability of the car. Worst tires I have ever used. Now I'm running BF Goodrich G-Force T-A KDW on 17" ~36psi all around. Very happy with that setup...
I couldnt speculate on why your car wandered on the tires, but my car tracks the same. My BF Goodrich are directional. Maybe your Summi's were too and installed incorrectly?

Tires can do this a little. The offsets that we get from other porsche wheels will -greatly- magnify this.
