typically, when you roll fenders, you're not so much removing that extra bent-in lip along the wheel arch as you are flattening it. problem is, as the fender roller applies pressure on the inside edge of the fender, it pushes the fender edge outward, creating a "pull" effect. for the 2is, it ends up disrupting the body lines on the fender sheetmetal. and if the fender rolling is half-assed, you end up with cracked paint along the edges.

cutting/shaving fenders remove the material to maximize tire/fender clearance, but doing so may weaken the structural rigidity of the fender. however, because there is no pressure exerted on the fender, you won't disturb the body lines. just remember to apply a dab of clearcoat along the shaved edge, lest you end up with bare metal exposed to the elements.

some swear by one or the other, but both are pretty much irreversible.

 

sorry, please explain it to me like to a child. i don't get it..

 

it just means that the fender will physically rest right on top of the tire when the car isn't moving.

but when it is, the rolling motion of the tire will create two scenarios. best case, the tire will rub against the fender, and it'll create a nasty rubbing noise, maybe a little tire smoke, and possibly cause small bits of tire to rub off. worst case scenario, the tire catches on to the fender, pulls it outward, and then the exposed area shaves the tire or slices into it.

granted, all that is assuming that your ride height is low enough and your wheels have low enough offsets to actually cause that to happen. but given a heavy enough of a load (whether by axle or side), it just might.

but you never want a "tire, meet fender" situation.

 

yes okay, i get that. and this is why we have so strict tests and regulations, that a situation like this never can happen, if the tires will rub, i won't be allowed to drive in germany until i get rid of the wheels..

so i need to know if f: 19x9 + 26 r: 19x10 + 23. or f: 19x9 + 38 r: 19x10 + 36 will hit ever hit the fender or something else in the area.

with a 225/35 tire and 19x9 + 26 in the front, will i be able to do a full wheel turn when the there is no suspension travel left (damper fully compressed) without hitting the fender or fenderliner?

I want to order the work vs xx wheels, but i can't spend over 5000 euros just for wheels that i probably won't be allowed to drive.. i hate to live in germany sometimes. :C

 

Thank you projectdna.

 

19/9 plus 32. 235/35/19
19/10.5 plus 38 275/30/19

What will need to happen to make these fit? Just a rear quarter roll?

 

i'd roll all around just for the heck of it, but the rears might not even need a roll

 

docfreud, go with the second setup

 

The fronts would need rolled to with that setup?

Thanks for responding quickly

 

19X8.5 +35 19X10 +40 WITH 235/35/19 AND 255/30/19, lower with coilover about 1 finger gap. would it rub? thanks

 

mym3 go with a 225-35 front and 245-35 rear with those offset you should be good.

 

thanks a lot

 

25 offset in the front.

 

I feel like after getting so much help from this thread I should contribute a little to it. A lot of question arise on fitment regarding roll and what not, maybe this could be a bookmark of what an IS can fit with or without roll.

My current setup

19x9.5 +24 (225/35)
19x10.5 +23 (255/35)

I was able to fit the setup above with roll all around, no pull/no camber kit. I am although a bit low, but bare in mind upon driving home a huge part of my front corner fender liner was torn up with some tires. The rear clears and only rub on dips. I have yet to do alignment and relocate the front tab though. I believe it would be much better after it. Here's some photo:




My old setup:

19x9.5 +35 (225/35)
19x10.5 +35 (255/35)

was achievable without a roll in the rear, but needs a roll in the front. Hope this help for people achieving that aggressive look.

P.S. Does anyone have link to front tab relocation DIY?

 

to clarify, your fenders were lightly pulled from the pressure of the fender rolling wheel being applied to the inside of your fenders. however, that's not a full-on pull as "pulling" would suggest.

the need for fender modifications isn't solely dependent upon one factor but several, such as (but not limited to) wheel width/offsets, tire sizes, and ride height.

anyways, with that out of the way, thank you for your contribution.
