Actually, would 17x9/+42 with 235/40/17 be a better fit? I don't want gigantic wheels but I want them to compliment the fender flares.. And I have also heard 235 is best performance wise.

good god. you can fit at least a 285 on 18x9.5's WITH flares. Why the hell would you want anything smaller???

17x9 +42 with a 235/40 would look HORRIBLE with flares. As in there is absolutely NO point to having them because that will fit under STOCK fenders (with NO roll).

If you're set on the flares, go big or go home. 17x10s with a big meaty tire (285 or 295) would be great.

I was just saying that you can go with a 9.5 with a narrower tire without having to mess with anything more than a roll and slight pull with some camber.

Thanks for making me laugh I'll just stick with what what I originally posted.

I've learned so much over the past few days about offset - thanks largely to this thread. Great info and thanks for getting it started / keeping it going. It helped me avoid a two hour trip to pick up wheels that a "reputable" website said would fit, but in reality they'd get me into that gray offset area. So why is it now that I find a wheel that's the same 5x100 with an offset of 48 and I'm gun shy to make the purchase. Well I'm looking to put wheels on a 2012 Impreza Sport and found that the 2012 Forester has some nice looking ten spoke wheels that fit the bill. I guess it's the fact that they're coming off of an SUV and going on a, well I guess a car that goes through snow like an SUV. I guess I'm not asking for advice, just a nob about to be taking delivery of his first Subaru. I think these are the wheels for me!

i have a set of OZ ultraleggeras laying around 17x8 et 35 running 235/45 tires from my old VW.
would these not be safe to run on a 12' wrx?

Based on the info I've been gathering after doing a bunch of research on fitments, you should be fine with that setup. If they clear the brakes, then there most likely won't be any clearance issues elsewhere since that is the stock size, both tire and wheel width. However, the stock offset is 53, so with your 35's you're gonna get a little more poke out of the wheel wells. But like I said before, if they clear the brakes, then you should be good. The only time you would run into an issue is if you were to lower the suspension, then the offset might cause wheel rub. If that's the case, you would have to roll or pull the fenders or induce more negative camber.

Too bad it's not a clearance issue. Read below.

VW uses a different seat for the lugs. You'll need custom made lugs, or I've hear that there are conversion washers you can use.

Ah crap, you're right. I forgot that "little" detail about the lug differences. My bad.

I'm planning to get these set 19x9 +35 offset and 245/35/19 tires on it. Does it fit perfectly on an 09 Sti? without doing any fender mods.
Or should i go with +25 offset

sc00by4life - i was under the impression most VW/Audi used a ball seat.

Also, keep in mind that Audi/VW fitments are all over the board as far as PCD goes. So you'll either have to make sure that the bolt pattern matches up, or you'll have to get custom lugs and/or conversion spacers(although I'm not a fan of using spacers ever). Also, the seating is important like sc00by said and as I'm sure you're aware.

this seems to be the best place to ask, someone feel free to tell me if there's a separate thread or if I should start a new one.

current wheels/tires are 18x8.5 et48 and 245/45/18. The tire is a bit tall, but fills out the fender nicely. However, on a hard corner, I get some rubbing up front. Its really just on the tightest of corners where I'm almost at full lock.

I'm thinking about switching to wheels that are 18x8 et38 with 225/40/18 tires. based on the offset calculator (http://www.1010tires.com/WheelOffsetCalculator.asp), i'll extend 4mm closer to the fender. BUT because of the tire, I'll be running a smaller overall diameter by ~1.6".

Think that will rub? will dialing in a bit of camber help? maybe a degree or so.

edit: will I basically have 1.6" more room for compression?

Your rubbing on the liner not the fender, and it's because of your ridiculously tall tire.

You wouldn't rub with the weeks you have now if you didnt buy a stupid large tire.

They actually came with the wheels. so I didn't go out and buy them separately.

Also, I took another look at them and they are actually 245/40/18. So not super huge like I had thought.

One bit of info that I missed was that I'm lowered on coilovers. Maybe I just need to throw them back on and dial in a bit of camber.

Ok, after reading this thread I am trying to grasp what will fit correctly on my 2010 impreza 2.5i premium.... Some sites ask if its a premium specifically and some just ask whether its a base model. I'm not sure if it actually makes a difference, but they seem to think so.

I am trying to get a set of Rota Grids 17x8 or 17x9 and currently see the following specs.

17x8 - 5x100 - +35
17x9 - 5x100 - +30, +35, or +42

Can someone help me figuring which option is going to be a direct proper fit?

Base vs premium makes no difference in wheel clearance. All that determines is what kind of interior amenities there are.

17x8 +35 will be too aggressive of an offset. You might have to roll the fenders and it will put added stress on your wheel bearings.

17x9 +38 will be a good choice. Depending on the tire size you choose, you might have to roll the fenders.

Thanks for the fast response. So, would 17x9 +38 with 225/45/17 be fine without rolling the fenders? I'm taking it that +35 would stick out from the car too far, +38 would fit properly, and +42 would sit in too far and rub on something internally?

+42 should not be in too far as to cause problems.

Are you planning to stick with stock sized tires? That'll make a big difference, along with any planned suspension changes.

Is really going to be your friend for finding out about fitment on your car.

+42 would be the best fitment for you without needing to do any fender mods.

but if you dont want to do fender mods, why dont you run a smaller wheel and a slightly larger tire?
