I'm currently trying to fit 285 rear tires on my Z, but I kinda debating whether to have my fenders rolled or cut. I live in AZ so rust isn't a really big issue, but I've heard that sometimes when rolling the fender it would actually warp the fender. What's the best way to make room for 285's roll or cut?

 

they said when you cut, the body structure become weaker. ???

 

Roll them. When you cut you are cutting the spot welds holding the inner/outer fender together. Even if you paint the edge, moisture can get in between and over time rust out your fenders....I rolled for less than $100

 

The guy at the body shop said that rolling the fender would cause the fenders to warp and ect... and he recommended that i cut em... But I've been hearing different things. Another thing is the they are charging me $160 to roll, and $80 to cut both rears.

 

most bodyshop recommend cut because it's faster for them. Speaking of rolling, is the paint chipping too?

 

A body shop I went to told me the same thing about warping/chipping. He wanted $300 for cutting. If done corerctly with a tool (not a baseball bat old school way) the rolling WILL NOT warp your fenders, I had it done, no visible difference on the outside, and made my 19X10.5" rims with 285's clear....trust me, have them rolled by somebody with experience. BTW my paint didnt chip.

 

dont cut them.. they do make the fender weaker and I'm told, in some cases just leaning on the fender can cause it to warp or dent because that lip and spot weld structure is not there to reinforce the fender anymore..

yea.. u guys do make a good point. It's probably worth the extra money for rolling. Worst scenario would be repainting fender instead of replacing whole fender.

 

Why do you have to roll to fit 285's, i mean its close but you shouldn't have to roll to fit 285's. I have 285's on a 9.5 w/ +33 offset and they aren't rolled. I guess it doesn't matter whether you roll or not at 285 or 305. Anyhow, yeah roll them don't cut.

 

i have 285 with 29 offset. For somehow, after i put on the rear BBK, it insanely sink down and rub. Weird.

 

i believe my rear offsets are +23 on a 19x10.5

 

I had 19's with a 275 on the rear for the last year and they were fine without rolling. Then I got the AAM stage II fuel system and the 3' True Dual exhaust. I guess this added just enough weight to cause me to start rubbing. Sucks. But I want to go to 295 or 305's anyway... So fender rolling is high on my to do list right now...
From everything I have seen and people I have talked to, rolling is the better option for a majority of us.

I've done a couple of fender rollings, and they have always worked out fine.

I even did a brand new Jag and everything turned out fine. One thing I did use was a wooden bat. It seems to lessen the impact than from metal to metal, and does not scratch the paint at the contact point.

If you do it yourself, just take your time and do it on multiple passes.

Good luck.

 

I cut my fenders with 285's on a 19x10inch wheel and 15mm spacers and a 1" drop all around. Funny thing is I thought I was going to rub and it isn't even really close after I got my rear negative camber taken out. With the rear wheels at -.8deg camber, the car actually sits slightly higher in the rear and gives more room for the wheel/tire.
