on 19x9.5 rear and 19x8.5 front without rubbing. I want the wheels to sit as flush as possible with the fender lip, but I don't want to rub. I am also planning on running eibachs so please take that into account.

I have read just about every wheel thread on here doing research, but really never found this answer out. I have seen tire/wheel packages that work, but they all look like the left something on the table as far as offset. Most cars see to look like the wheels are sucked in, I want them flush. Is it not possible to do that with these cars without rubbing like the bimmers and audis can do.

With those widths, I'd say 38+ all around.

Which rims are you looking at though?

this will be on 19x8.5 front and 19x9.5 rear

i have heard 37mm front,36 out back...... but i have seen 350z wheel fittments on a IS before, just some fender rolling is required.

I think I am going to run MRR GT1 wheels. I think the 36 front 37 rear sounds close.

I am running +34 front and +36 rear

But i do rub a little up front when turning lock to lock

I'm running +36 all around, but the "most aggressive" has to do with how wide the tires you plan to run too.

I'm running 19x8.5 +35 with 225-35 and 19x9.5 +30 with 235-35 with no rubbing and no fender mods.

those are some very narrow stretched tires on those 8.5 and 9.5 wheels. I really don't want to go that narrow. Thanks for the reply though. I will weigh that into my evaluation.
Yeah I am sorry for not posting my tire size, I am a dummy. 235/35/19 front and 265/35/19 rear.

Thanks for the help guys, keep it coming. I would like to see some pics of your rides to with these offsets. We should set up a stick with offsets and tire sizes.

FWIW, if you are depending on your springs to avoid rubbing, you are making a huge mistake. Ride height should never be a consideration for does it rub or not. The tire should never rub at any point in the suspension's movement. If you expect your springs to alleviate this, you will cut a tire on a bump in the road one day.

There are two factors to consider when checking rubbing - camber (which is currently a non-player because we have no camber adjustments) and offset. Sure you can stretch a tire to fit a wider rim and gain a little clearance, but this isn't a practical solution for a daily driver. Great for a show car, not for the one you want to drive down your average street with potholes, speed bumps and other urban obstacles.

So, in keeping with the OP's intent, it would be great to have a list of wheel sizes, offsets, and tire sizes that are NOT rubbing for the owners under any circumstances. It would also be handy to mention the combination's size relative to the stock 17's and 18's to get a good picture of unintended effects (speedo, odo, VDIM, etc.)

JMHO...

If people would like to PM me with their setups, I'd be happy to make a chart and get it posted in the FAQ. I think this would be a valuable addition to the site!

sincityIS

yeah you are right about that lobuxracer. Now lets get this guy some setups to post.

Actually....this depends on the tire. The Dunlops I'm running have a very blocky tread and there's hardly any stretch on my tires. I'm guessing I could still run 235-35 / 265-30 with a Falken 452 with no problems either.

depends on your drop...right now. im at 28 offset front, and 33 rear...only rub during big turns...about a 1 finger gap all around...im at a good flush look.
