Good info just got my 2011 wrx last week. Since i dont want to roll fenders going with 18x9 265/35/18 38-42mm offset. The 1/2 inch should result in no rub.

Stock suspension.

More camber can help but the suspension is too soft to properly handle those wheels.

I knew there was a high risk, but of course stock suspension is not here to stay . Coilovers coming.

offset > wheel width when it comes to rubbing. you want +42, +45 would be even better.

Thank god for this thread! Was wondering what would rub/need rolling since I bought the car two weeks ago! Gunna play it on the safe side so I dont have to roll and go with some 18x8.5 +44 245/40/18.....just waiting for someone to make some effing struts so i can lower with new wheels all at once!

Thanks for the reponse Dan, I realize now that going +40 or +38 on a 9.5 wheel is necessary for tire clearance and if I am going to get new wheels, may as wheel go 9 or 9.5 since i already have 8.

I have a 2011 WRB WRX sedan, and would really like to avoid fender rolling if possible, although I am not against having it done if necessary. This is a daily driven car that I am looking to mod and build up over time, and will eventually be getting coilovers as well. I have NO intention of lowering the car ever, as it would be a disaster on the roads where I live in combo with the larger wheels/tires.

I do have a few more questions and hopefully im not bugging you too much, really appreciate any adivce you have to offer

I have seen your Rota D's 18x9.5 +40mm online and saw that they weigh ~26lbs a wheel, which in my mind is a very heavy wheel. I'm not sure of the exact weight of the OEM wheels on the 2011's, heard they were ~18lbs? And I know that the added weight of the 4 new rims( i.e 8lbs greater per wheel, 32 bs total) is not the total affect on the car as the new wheels have greater mass further from the axis of rotation sooo what im asking is: Is it worth adding that effective extra weight in order to take advantage of the much wider tires (i.e 265/35/-18's) ? Keep in mind I do plan on adding power mods/swapping out that weak ass 5spd trans in the future (once I get xxx whp)

Also I'm wondering if the 265s on the 19x9.5 will rub where I have a sedan as I heard that my rear fenders have slightly better clearance than the hatchback models, not sure if that is correct?

And if I do decide to go with those wheels/tires(good chance going to be Dunlop Dirrezas) and I dont have any rubbing, will there be rubbing if I have 3 other people in the car with me? Or will they only rub if I were to push the car hard with that added load?

I know I've got a lot of questions and info there, but I really would like the advice of a professional like yourself as I certainly don't want to invest in a set of new wheels, only to find out later when I begin to mod the suspension, i.e coilovers, that I can no longer use those wheels (remember that I will NOT be lowering the car at all)

Really appreciate any advice you have to offer, thanks for your time!

Edit: I will also have larger sway bars/endlinks combo before I look at buying new wheels, which should help reduce body roll induced rubbing until I get coilovers to stiffen up the suspension and hopefully completely resolve any rubbing issues, that is of course, assuming that they never rubbed in the first place :P

That'd be nice. If memory serves, though, they're more like 22 pounds.

The OEM five-spoke STI rim from 2008-09 is around 28 pounds. The more recent 18x8.5 Enkei STI wheel is 23+ pounds. The late-model STI BBS 18x8.5 is a bit over 20 pounds.

You are right -- rotational mass counts as more weight than static on-the-car mass, because to speed up or slow down the car, you first have to speed up or slow down the wheels. As a rule of thumb, multiply the difference in wheel weight by 1.5 to get an equivalent change in static weight. That is, one pound more of wheel weight is like 1.5 pounds of car weight. Of course, as you mentioned, there are four wheels, so it's 4x the single-wheel change.

Quote:

That's up to you. For me, yes. Added grip (and as a secondary benefit, more aggressive looks) are almost always worth the nearly imperceptible increase in mass. If you put a 35-pound box in the floor behind your front seat, could you feel it while driving around? I can definitely feel the handling difference from a 20mm wider tire!

Quote:

We have not noticed a substantial difference in clearance between hatch and sedan. I'm not sure if you can get a 19x9.5" wheel in a high enough offset to clear in the rear without rubbing if you don't roll the fenders. Perhaps a +48 wheel would do it, but I've not seen a 19x9.5 +48. Also, the tires might rub the struts in front with the offset that high. As I've mentioned above, we run a 275/30R19 on our 2008 hatch with a 19x9.5 +40. Once we rolled the rear fenders, no rubbing.

The farther the suspension squishes down, the more likely you are to have interference, but I can't really answer your question one way or another. It's certainly going to be more likely to rub if you have a car full of people, but that doesn't mean it WILL.

Are you seriously going to be "pushing" the car with three passengers on board?

Sway bars will keep the car flatter in corners, but will NOT help with straight ahead bumps like freeway bridge transitions and railroad tracks.

Ok great, and no i wont really be pushing it when having 3 passengers :P haha that was more of a hypothetical situation.

Oneee last question, you mentioned in a previous post (I've read this entire thread) that the ideal wheel width for a 275 tire is 9.5 inches, will a 265 fit best on a 9.5 or 9 inch wheel?? And in your opinion, does the much wider wheel in combo with the lower offset make steering feel that much worse? Since this is a daily driver, I really dont want to have something that will annoy me or is it very liveable and just takes getting used to in your opinion??

If im going to have to roll the rear fenders regardless, which doesnt really bother me, Id love to be able to run 275 width but how much more trouble would that make rather than just sticking with the 265s?? What would you personally run on yours if you were to go with 18x9.5 wheels?

True enough, I hadn't thought about the bridge transitions etc, so in order to try to resolve those type of rubbing issues, would coilovers be sufficient?? Remember, I reallllllllly dont want to lower the car at all, and I havent seen any coilovers online as of now that retain stock height, so would sways/stiffer springs combo be compliant or no? Looking for your opinion haha

Thanks again Dan for the help and advice

The 9.5 is pretty much perfect for a 265.

Quote:

The offset is a bigger factor than the wheel width. Keeping the offset closer to stock keeps the steering feeling right. The further out you go, the worse it feels, in my experience.

A moderate change in offset will hardly be noticeable after a while.

The Star Specs are a pretty fat tire. You'll be much better off with 265s in terms of overall clearance.

In the Star Specs? The 265's.

They help because you can adjust the ride height as needed, and you'll have harder springs, which resist large suspension movements.

The stiffer your suspension components get, the harder the car will ride. There's really no getting around that. As you mentioned, there are not many options for upgraded suspension that don't lower the car. The RCE blacks are one possible solution.

Would you personally get the RCE blacks or yellows?? I wouldnt really mind a 15mm drop just dont want anything drastic. And yeah I'm pretty sure im going to get the star specs, but what about the Advan Neova AD08 or Potenza RE-11s?? If i were to install those springs, say the yellows for example, along with a set of sways, in your opinion do you think it would be safe to run a 275 width? Obvi if those star specs are fat id go 265, but as far as the other two go, would 275 be a safe bet??

They're 8" wide, so a 245 will fit easily. 255 is pretty balloon looking, but can be done.

Up to you. For my money, 5mm still leaves the car looking lifted.

Look for some of the tire review threads for answers.

There are too many variables to say what's "safe." Again, we run a 275 on our shop car, and it works great. But that's no guarantee your car will end up the same. The last thing I want is for you to be saying later, "Mach V Dan said it would work great, but it rubs!"

Yeah completely understandable, tho I would never hold it against someone like that

I think I will go with 265s at first and maybe go bigger later. Those yellow springs, would they help as much by themselves as say 24front/22rear sway combo would alone? Just wondering if I could get away with just the springs until later with the new wheels/tires or would I need both?? Do you have any idea what the stock spring rate is??


Really really appreciate your feedback btw man, Hope I'm not driving you nuts haha

Im planning on using my stockers as my dedicated winter wheels and throwing a set of blizzaks on this fall. I will still have probably 70% tread left on the stock 245/40R18 Dunlops. Ideally, id like to put some 18x9.5 Rota DPT style wheels with a 40 offset. Is there any reason i cant stretch the 245s onto the 9.5s or am i better off trying to sell the Dunlops and go straight with a 265. Im not looking to go with the "stretch and poke" look but id hate to lose a ton of value in the stock wheels which, for my use, are just fine.


Thanks.

Read through this thread. There are several pictures of cars running 245's on 9.5" wide wheels.

So I read through the whole thread and noticed its pretty well geared toward 18" wheels.

My question is about the following.

17x9 +35 with a 245/40 tire.

The car will be on GTworx bilstein/RCE yellow combo

Any thoughts??

Go with a 255/40 to keep aspect ratio closer to stock. In addition, rolling will be required.

STU autocross rules only allow up to a 245 tire.

Even with the 245 I should expect some rear inner lip rolling?

I'm finally starting to narrow down what I want.

19x9 +35 Advan RS-D (black with machined lip, clear brembos?)
255/35 R19 BFGoodrich g-Force T/A KDW
Tein Coilover (most likely flex, if not monoflex)
GT Spec Rear Control Arm
GT Spec Rear Trailing Arm
Whiteline front and rear sway bars

I'm looking for a nice semi-flush fit, no problem rolling the rears, will be a drop around what the coilovers gets but might go slightly lower. All going on a 2011 PBP Sti, no auto-x, just a daily driver.

Any advice/suggestions?

I have a 2011 WRX as well. And was hoping to put some 16 inch rims and 16 inch snow tires. I'm looking for a wheel size that will fit 205-55-16 tires and will fit on the WRX.

I'm just looking to know what 16x(?) 5-100/(?) wheel size would fit?

I should be able to go 16x6.5 5-100 & 16x7 5-100? Will I have to go 215-55-16 then?
