Taking a grinder to my FD

I am getting some very minor rubbing on the inner lip of my wheel well in the back due to my rims. I hate rolling the fenders bc it often comes out like crap. Can I sand down a 1/16th of an inch in a two inch length on the top of wheel well?

I would just roll it, it's extremely easy if you have a roller and heatgun.

You are either not using the proper tools or are rushing the job if it usually comes out poorly.

I don't know. I have a bad experience with a pro doing it. It's so minor. I just figured I would shave off a very minor amout at the top of the well with a dremel. No good?

The edge will then be exposed and will inevitably start to rust. Sure you could then dab paint all over there, but it's going to end up looking more hokey than a half botched fender roll, IMO.

Yeah ur probably right. I guess I will raise the ride height a little. Start there

If it is that minor, you could just add some negative camber to the rear!
----------

You can use a Dremel and cutting wheel to trim the lip some (don't grind, it will put a bunch of heat into the fender and take time), but you will have to repaint it. If you trim too much you are going through the spot welds of the 2 sheets of metal and will weaken the edge slightly.

Make sure to round the sharp edges left by cutting in case your tire does contact it again!
----------

FD rear is easy to roll with a fender roller and if you don't have fenders full of bondo.

Just go slow with the roller wheel ~ 15 deg angled to the lip with some heat to keep the paint from cracking and keep adjusting the roller wheel angle as you go all the way to vertical (matching the outer fender profile).

Don't try to roll the lower parts, just the upper lip.

Whatever you do, don't pull the roller toward you or up with excessive force while rolling this lip under, that is how you get waves, creases or the dreaded dimple above the fender.

Don't try to move the metal all at once. Take it slow with repeated movements across the arch with light to medium pressure while pausing to look at what the metal is doing (use a drop light or flashlight).

You are fatiguing the lip until it folds over and that is done by repeatedly flexing the metal.

Once the lip is vertical with the fender you are done unless you want to proceed with a pull for even more clearance.
------------

Things get a little riskier with the pull or flare.

For a pull, adjust the roller wheel the other way ~15 degrees from vertical and roll with medium pressure up and out toward you. Check the reflection in the fender arch to see the edge starting to flare out.

Once it starts to flare you can adjust the wheel for more angle if you want that curved lip look (flare) or keep pulling the fender toward you and slightly up if you want to stretch the metal into just a pull.

yup, neg camber bay-bee

As I recall Mike's old FD had pretty OEM-ish alignment specs.

Roll the fenders. It comes out nice if you have the proper tools and technique. We do it at the shop all the time.

24 7/8th. I guess too low. Could have sworn I raised to 25.25. Maybe with new tires something is different. Anyways I will raise a half inch. It's lower than front so will probably look better. I can't even get a finger in there. It's probably rubbing worse than I thought too. I hardly drive this thing. More just look at it.

She doesn't hook up with these tires either in first gear.
