Default Rolling Fenders....

I've tried searching, but here it is anyways.

It'd be nice if someone can make a noob write-up for rolling fenders, what it is exactly, and to determine if your car would need it. I've seen very few threads about whether or not cars with certain offsets, etc would need the fenders rolled.

Some questions:

1) Which secnarios would you need your fenders rolled, is it with agressive offsets and/or wide tires? If someone could please elaborate on that.

2) I have some Volks with 19x9.5 +22 and 19x10.5 +22, and hope to get tires somewhat like 255/35/19 fronts and 285/35/19 rears. Would this also be a scenario to roll my fenders? If so, would I just have to roll the rears, or front too?

3) I've read how some people said they were hesitant at first to roll their fenders, but once they did it was not bad. How do you know how far to go, when you start to roll your fenders?

Thanks.

I have a thread going about rolling fenders, and the specs I have are apparently at the cross between having to roll, and not having to roll. I hope the specs you have are more cut and dry for people with experience to look at and tell you if you need a roll or not. Good luck.

basically agressive offsets... aggresive offset paired with wider tires makes the setup more aggressive; ie more likely to need a roll

2) I have some Volks with 19x9.5 +22 and 19x10.5 +22, and hope to get tires somewhat like 255/35/19 fronts and 285/35/19 rears. Would this also be a scenario to roll my fenders? If so, would I just have to roll the rears, or front too?
the fronts are 'rolled' from the factory. On the fronts, you would have to do a fender 'pull' to provide clearance. On the setup you listed above, it will most likely depend on your camber. the more negative camber you run, the less likely you need to roll. If you bumped up your tire size to a 295, you most likely would need to roll -> and yes, we are talking about the rears

3) I've read how some people said they were hesitant at first to roll their fenders, but once they did it was not bad. How do you know how far to go, when you start to roll your fenders?

Thanks.
In response to the 3rd question, rolling is a big deal IMHO. You basically ruin the paint with a roll by stretching the metal and breaking the bond with the paint. Even if you don't see cracks at first, you have damaged the paint. I would plan on a repaint at some point. In addition you are rolling the lip that the rear quarter attaches to the inner fender well. this makes replacing the inner fender well mandatory if you are in need of a new rear quarter.

Are there any drawbacks to cutting the rear fenders with a dremel or similar tool other than having to touch up the bare metal edge left from cutting? The only drawback that I can think of is the heat from the cutting process affecting the surrounding paint somehow.

Oh wow, is there somewhere I can go, maybe an autobody shop, that could do it professionally? I'd rather not mess with that sh*t and mess it up. My car is at stock height and camber I believe. What if I were to go wit a 275 R tire setup respectively, would it still be necessary to pull the rears? How differently would it affect me if I were to get a .6/.7 drop, from the Tein S-Tech springs? What if I were to get coilovers? I know coilovers are better in general, and in the long run but I do not know how it would affect much. I'm still looking and reading around.

Thanks.

Cutting also weakens the quarter panels.

no autobody shop will garauntee their work unless you have them repaint the quarters after they are rolled

How many "Can/Should I roll my fenders?" threads were started this week?

I'd like to know as well, there's way too many things to keep in mind, and not everybody's vehicle is the same. Just put it on, and if it rubs, roll it, if it doesn't, leave it alone.

If you take all the precautions when you roll your fenders (proper fender roller + heat gun), and you get a crack or two, do these small paint cracks "run" like a crack in glass?

even if you don't see cracks, your paint bond has been compromised. eventually there will be issues...

Would it be a crack in the paint, or the crack in the fender? I'm probably going to have my car repainted soon, so if it's the paint, then I can go ahead and proceed.

I'm not sure how long you mean by eventually, but there are members on this forum who have had their fenders rolled for years with no paint problems.

I'm still trying to find out if paint cracks "run". Anyone?

I have these exact specs on my volks with 255/35/19 and 285/35/19 Toyo T1R on my 350 at stock height and I have no rubbing issues at all. I would assume it would rub if I decided to drop the car though.

Interesting. I planned on getting Michelin PS2's or Pirelli P-Zero's, but my main thing is if I were to drop like half of an inch, or somewhere in that ballpark using Tein S-Tech springs, would I need to roll fenders then, and adjust camber settings? Or could I get away without rolling and adjusting camber? The stock ride height with aftermarket wheels = huge wheel gap.
