Need a drop?

Nah, there is nothing saying you need to lower the car, is there?

Shouldn't be any issues as long as you keep your tire sizes correct. And make sure the wheels are hubcentric, or get hubcentric rings.

Thanks for the info

Hi spa-zz,

since ur the local guru here I wanted ur help.

I was wondering if 1-2 difference in offset from the minimum required would cause it to rub on a lowered car on eibachs and stock strut.

I was looking into a set of some 17x7" +42 205 fronts and 17x8" +48 245 rears..

Looking on ur chart there is a difference of 1 for the front offset. So will this cause the rub?

thanks

 

The tolerance in these numbers is probably a few mm either way, so there is no guarantee that you will rub if you run an offset that's 1-2 mm below the minimum. These are just guidelines. Every car is a little different, and alignments make a difference too. However when you lower your car you usually increase your chances of rubbing. This guide was not based on lowered cars, so I can't make any promises.

 

If you have the suspension mods to go along with a non-staggered setup, then great.

If you don't have your suspension tuned properly, and you remove the stagger, you are setting up your car for oversteer.

It doesn't matter if you don't plan to track the car, or just cruise around. What if you need to avoid an accident? Or a pedestrian? You could end up backwards against a tree, because you thought it would be cool to be able to rotate your tires.

IMO, keep the stagger. It's not that hard, and it's safer that way.

 

Ok, I hate to be the next "Will this fit" guy, but here goes. I've studied almost every topic in this wheel and tire section for the last 5 nights for about 4-5 hrs. a night, and finally I've found the set of wheels I want and I believe the right sizes according to the first page here. 2004 Vortech'd car with 18x8 +64mm 245/40/18 Front
18x10 +64mm 275/35/18 Rear
I like the shoulder of the tires to be even with or protrude alittle wider than the wheel, to help with accidental curb rash. Also, I like the wheels and tires to line up smoothly with the fenders, like most people on here I've seen, but not too far as to rub when I hit big dips in the road. What do you think? Overkill? Rubbing? When does it get to be too wide and the offset actually rub something on the inside of the wheelwell and shocks?

 

With those offsets your tires should be very close to flush with your fenders because you are close to the minimum offsets. You shouldn't have rubbing problems, but there are of course never any guarantees because every car is a little bit different. Rubbing on the inside of the wheel well is much less common because there is quite a bit of clearance in there. I know people have run 10" wide wheels with 275s before without interference, so you should be OK.

Did you find a set of wheels that meet those specs, or are you just dreaming up your ideal wheels?

 

Thanks spa-zz. I did actually find wheels with those sizes, I just didn't want to drop 700 a piece for them if they weren't going to fit. I should be ordering them in about 3 wks.. I'll post pics for reference. Also, I know it is different when you drop, but, I want to drop maybe 1-1.3". Do you think that'll be a problem if I keep my suspension adjustments calm for street use?

 

I don't think I can really comment on what your results will be when you lower it. If you don't reset your camber adjustment back to stock settings after lowering it shouldn't rub but if you do, you will bring the top of the tire closer to the fender which would increase your chance of rubbing. Depends on how much camber you feel like running. I suggest if you end up with a lot of camber then be careful how much toe you use or you may find yourself buying new tires frequently.

Cheers.

 

I've got a bit of an esoteric question.

Cliffs Notes: Front wheels. CCW Classics. 17x7 +49mm. 245-40-17 Hoosier A6s. Stock ride height with maximum negative camber (about 2mm on the last rack I used). Will these tear the fender liners out of the car?

I use the stock AP2 wheels as my autocross wheels currently, with the 245-40-17 Hoosiers on them. To my knowledge, they do not rub - at least, not in any way that is poblematic. What I'm trying to anticipate is whether or not the CCWs will rub with the same Hoosiers on them. They are 6mm more aggressive on the offset at +49.

The reason I ask is that a couple of the CCWs need to be sent back to repair a minor air leak where the rim halves come together. I'm trying to determine whether or not I need to have them put back to factory offsets while they're off the car.
