UPDATE to Shaving rear fenders

I will be shaving my rear fenders starting today and was wondering if anyone had done this? Is there anything i have to worry about like metal seperating or anything like that? Any pointers would be greatly appreciated!! thanks


PSS tires 275 30 19 on 11 et25 rim fits really good with a little stretch nothing to drastic though. Shaving has worked so far I've had two pple in the back 150lb each but i have not gone over any real bumps yet nor have i been on the highway but no rubbing. We will see!!

I'm lowered KWvll and yes the needs to come down a little and so does the rear but thats where I'll start to see if i do rub. Where's my Dr. Pepper....lol

Did mine yesterday. Used a high powered electric dremel with metal disc's and a sanding roller. Took about 3-4 disc's on each side. Should take about 2 hours if done right. If you cut close like i did and left a tiny ass lip(because i need room to fit my huge wheels) then the metal will separate, not much though, like 1-2mm apart maybe. Plan on coating the inside with like plastidip or something so no rust forms.

Tips:
-Use painters tape to basically make a guide for where you're cutting, basically you should be cutting right at the edge of the tape and also put the tape anywhere you think sparks may hit the paint
-Make sure you have glasses lol, getting that shit in your eye would suck
-Before you actually get deep into the cutting, make the line with the dremel or whatever you're using so you can use that as a guide all the way around on the fender lip
-Keep a firm steady hand, sometimes the disc will get caught and cause it to jerk into your paint, not good
-Last but certainly not least, TAKE YOUR TIME

Have any questions lmk.

Heres what mine looks like(before touch up paint):

The lip is only 2-3mm thick. If you were to cut it more, you would expose the inner metal that separates when you shave your fenders and you would end up with a bigger gap in between them. I plan to get the inner sheet tacked to the outer so the gap doesnt get bigger when i do body work on my car. I suggest leaving a tiny lip like mine unless you can somehow push the inner lip against the fender without ruining the body/fender.

I shaved mines also and only got about 1-2mm of lip left but that sh!t is still rubbing. I would suggest using 3M Undercoat spray on the bare metal instead then use touchup paint to go over the Undercoat.

shaving

Just finished I'll have pics in a minute! It took about 2 hrs with a dremel then i sanded everything. Sealed everything up you can't tell i was in there. Getting ready for my 11's et25 hopefully this will do it with a little camber help but within specs. I'll find out on Thursday! I just free handed it plenty of experience on aircraft so this was fairly easy. You guys have rolled your fenders before so you know that lip that is formed from rolling right...I took over half of that off. That same lip is about 1/16th wide now.

What do you to with the wheel well liner once you shave the lip? It won\t have anywhere to rest and will sage. This will case rubbing as well. Do you cut the liner out as well?

Are you on a PRE LCI E90? If so you will be fine with 11 et25, what size for the front.

Yep! I asked and they said mines are custom built so they won't release that to me. The wheel itself has a flushed fitment except the tire I'm running is Michelin PSS which has a thick sidewall. As of now I'm still rubbing a little here and there especially when loaded.

How can you even buy a wheel without knowing offsets ? Off trusting the person/company selling them to you. Not the best idea.

Either way you can go measure them to find out your offsets just an FYI

Fronts are no problem.

You should be fine with a 275/30 IMO just run a hankook or something to get a bit of stretch. I run a 285/30 on my 12"with about -4 camber as of now on my LCI e90. Obviously I cut and shaved it but mine is a aggressive poke set up so YOU WILL RUB when going this route either way. Feel me

I wouldn't of known what will fit me best. They had to make these wheels to clear my BBK and make it flush. You're right! It's never the best idea not knowing what I'm getting. If I knew I would definitely selected my own specs.
