OK I want to put on 17x7.5 in rims with 42mm offset with 235-45-17 tires on with Comptech springs. Will it rub (I am guessing it will a little) and what will I need to do to keep it from rubbing? What is fender rolling? Can I do this my self? Does it change the look of the fenders from the outside?

Yes it will, and you will have SEVERE suspension resonance problems. take it from me. Discount tire bought back my original wheels after 2000 miles because we couldn't get balance right. we ruled out tires and whells because both were replaced.
The new ones are 17x8 with 50MM offset and comptechs will not be a problem.

he's right, even the slightest rub Will cause enough damage. I had to change all the bearings in my ford ranger because of a slight rub. It multiplies the pressure of the rub in cornering due to body roll then something has to give. don't risk a $2,000 headache.

The problem was with the offset . The car didnt have springs on it yet, and still doesn't. It caused a very BALOONY feeling with the steering

working off the tl-s...

i have 18x7.5 (42 offset) with 225/40 tires and lowered 2.1/1.6 with eibach prokits. the only rubbing i have right now is at the rear driver wheel and no where else. this means it's not the offset, but i think it has something to do with the lowering. this corner is kinda lower than all the other corners...i am looking at that now. oh, i only rub when i make right turns...no rub with left turns or on straight aways.

you have the same width and offset as my car, but you are going with a wider (235 vs 225) and taller (45 vs 40) tire, and your drop is not low at all (less than an inch). since you are not that low, you might not have too much rubbing problems on flat roads. but i do think you will have some when you turn and when your suspension compresses...you won't be rubfree.

but all of this is speculative. if you gotta have them, then you gotta have them. just deal with the rubbing when it occurs, if it ever does. this probably means you will have to shave or roll the fender lip. however, shaving the tip of the rear bumper that becomes part of the arch usually does the trick.

What does "rolling" the fender lip entail? Who can I get to do this and how much will it cost to have done?

rolling is bending the metal lip inwards and upwards to make more room. the ghetto method is to jack up the rear end with the wheels mounted, inserting a bat into the gap and then flattening the lip while you roll against the tire as a guide. the only problem is paint cracking. you are suppose to use a heatgun to warm the paint around the arch before and possibly during the rolling.

the better method is to use the haweka roller tool. you can rent this from the tirerack for the cost of shipping it to you and back. you will also need to put a refundable down payment as well.



an alternative is shaving the rear lip using an airsaw...all you need is a steady hand and there is not much else to worry about. all you need to do is maybe file the edge smooth and maybe touch it up with paint to guard against rubbing.

there is also a nibbler tool that uses a compressor to nibble half moons out of the lip. the only problem is it's time consuming.

you can check with some local rim shops about this stuff, but if anyone good with an airsaw and has the tools can do the shaving.

No need to screw up a 30,000 luxury car by rolling.

Simply just closer to the proper offset of +48 - +55
