Disadvantages of rolling your fenders?

I might need to roll my fenders in the rear. (have 285/35/19s and will be putting tein s-techs on) If I were to go this route and have a professional do it, are there any disadvantages in doing this?

Thanks!

Not sure, but I'll be finding out this weekend- putting 275/35/19s on with s-techs at the same time..

no disadvantage.
but if you car is low enough, you might still rub the screw inside, the screw that hold the bumper and the rear fender in place. It is no big deal tho!

Also, S Tech's aren't that stiff. When I had my 275/35 on 9.5" wheels installed (RPF1) I rubbed in the rear when anyone more than 175lbs sat in the back and those were advertised as "no fender rolling required". After the Tein Flex coilovers, I now have no issues but those are ~400lbs rear springs.

Why the hell are you going to a tire that is 1.5" taller than stock? You are introducing a 6% error to your speedo and the corresponding ABS and TCS issues.
At least do a 30 series tire.

I went with 275/35 over 265/30 which would have made my fronts taller than my rear. Since I'm lowering .7 rear and 1.4 front, might as well flesh it out with some rubber..

besides, at that point it's only .2 difference. I'm already rolling on 19's so if I gave a damn about accurate speedo I would have gone a different direction.

On random chance, do you think that's something which might be flashable?

the 35 series will make a difference. the rear ride height will be higher but it will appear tucked a lot more than the front due to the taller sidewall.

19/255/35 is extremely close to OEM setup of 18/225/45 so running 19" does not have to throw off the speedo.

why not 275/30? 275/35 and 265/30 are huge differences with tire sizes especially in diameter. Plus, if the rear is only being lowered .7 with that relatively tall rear tire is going to give it a funny looking nose rake. I did 245/35/19 and 275/30/19 and I can hardly tell that the front tire is taller than the rear even when the wheels are off the car. Its not even noticeable when the car is on the ground.

Your car doesn't have enough power to push those thing.

It will be a slug.

I had mine done at a place in Houston that specializes in Porsches. The only drawback was my smoldering wallet, as I was charged $75 dollars for about 20 minutes of work!

+1 and depends on wheel offset.

What's the offset and width of your wheels in the rear?

Get rid of those tires.

YOU NEED 285/30/19, this is not a 350Z. You'll totally screw your gearing and we don't have enough low end torque to compensate for the gearing change.

NO PROBS TO FENDER ROLLING. I do it all the time with the proper tools.

The rears are pretty easy to do.

No problemo with fender rolling. If you DIY, just be sure to apply sufficient heat so the paint won't crack.

A place near me said they would do it for $50 for the rear (thats all I'm worried about). I guess I just need to make sure they use a heat gun as he said, "we don't guarentee the paint from cracking."

I'm running the 275/35/19s now on rear with S-techs and have about a 1.5 inch (diagonal) clearance to the edge of my fender. I probably need to adjust the camber a bit, and while I don't rub with standard driving I have not really gotten 'aggressive' with it yet.
I'll check back in once I get it properly aligned and cambered.

look at my set up, no matter what i was rubbing with Tein S
so you will need to shave them
afterwards. it will rub only on crazed dips and driveways
or if you are loaded with heavy duty people

Would if I went to a 265 (or even a 255) in the rear? I just don't want to rub, I feel my car is too nice. Maybe if I had some older modded out car haha.

265/30/19s wont rub at all. I was running that prior to 275/35/19. I have a feeling these WILL rub when i hit bumps or load the car down.

What would be the best way to check for minor rub, chalk?
I'll try and get some updated pictures this week.


As far as handling, the car lost a lot of it's 'nimbleness' with the higher sidewalls. I definitely feel the sidewall flex. It isnt bad, but I also have not thrown the car through any real turns yet so we'll see how that fares after the tires are broken in properly.

The only rubbing from at least my set-up appears to be the outside of the tire rubbing the fender. I'm guessing at some speed it could put a slice in the tire. Don't see any wear related to it. I just hate having to listen to the sound of rubbing.

So would this be a good set-up? (Sorry I'm not too informed with the rules of thumb with staggared wheels or tires in general for that matter) I found this set-up for $555 (Generals, which I had on another car, not too bad) shipped from tirerack. A lot better than the $1100 for the set I have on there.
