Great thread, thanks for all the information guys!

Looking at going to 18x8.5 +38 on 235/40/18. Seems like I will be 21 mm closer to the fender in terms of the rim per the 1010 wheel calculator. However, since the tire is what will actually contact the fender and not the wheel, it seems like I need to lower this number since I'm not going larger in tire width vs stock. I'm just not sure what adjustment is required. Initially I was just ignoring the change in rim width, (which would mean 15mm poke) but I'm guessing thats not correct... Also, once I have that number (call it tire poke?) is there a general rule of thumb for how far one can push the tire outward before a roll is required?

I really hope I didn't mess this post up.

Thanks!

Asking those kinds of questions means you shouldn't worry about finding a lower offset.

Throw the wheels on the car and enjoy it.

There's one or two things happening here...

Either A) You don't weigh much and you haven't hit any BIG swooping type bumps like on a freeway or highway....hell...even a steep driveway or cross section at high speeds.

B) You don't ride with anybody in the car that weighs over 200lbs

This is pretty misleading for those looking for info because 99% of the time with your setup (this is my exact setup besides different brand tires) you WILL rub at some point or another ESPECIALLY when you decide to lower the car though in this instance is somewhat irrelevant because we're talking stock height

I advice anyone going for this setup to roll your rear fenders!

I'm not misleading anyone. I'm 6'3" and 220 lbs and I have had another 200 lb guy in the car on a ****ty back road with lots of bumps. No rubbing. I don't know what else to tell you. Sorry you rub? If you read this whole thread there are multiple people with this setup and they don't rub. Some do. So to be safe, yes roll the rears.

anyone have RSR that are driving in the rain? i'm looking at RE760's also. i might go with comp 2's again even though they arent the greatest in the rain.

looking at 265/35/18

i know RSR tread pattern is very aggressive just wanted some input. want sticky tires but with the weather thats been going on its iffy.

tough decision. stretch or flat with face. i still have to camber. i'll see what 255's look like and work my way from there.

265's have a minor stretch and 275's almost look flush with the wall. decisions decisions. *cough* battle wagon ^_^

Default Does the steering change much?

It sounds like a set of 17x9 +45 RPF1s with reasonable width tires will fit well. My question is how is the steering feel affected? I would hate to mess up the fine handling of the stock set up on my new 2014 WRX.

On stock suspension you wouldn't notice much difference. It depends on the tire you go with, really.

If anything the steering will be slightly heavier and with a 255 you might get more tramlining on the grooves of the road, but it won't be a dramatic differences.

The 17x9 rpf1's weigh significantly less than stock.

I'm not talking about wheel weight, but the effort needed to turn the 255's. Like I said, barely any difference.

I ran staggered RPF1s for 10 years on my 350z, fantastic wheels from the function standpoint. Their appearance my not be as contemporary as some popular wheels, but they are about as light and strong as you will ever find. Many pounds lighter than the factory 17x8s.

In terms of friction?

Because is imagine the rpf even with a 255 weighs less than stock.

Now that you have driven this wheel/tire set up for some time, what do you think? Is there anything you would change or do differently?

Pics would be awesome. I am thinking about running this setup on my 2015. Did you consider running 265 instead of 255?

Why would he even consider running 265's? 255's fit perfect on that setup

How flush do the wheels sit? Do you have more pictures?
