Well you are running a9.5" rim so there gonna be somewhat of a protrusion but without pics we can't really see if yours is normal or not

I'd go with a higher offset, like a +42. 18x9.5 +38 DOES stick out a little. There's not much you can do about it; like you said, you don't have adjustable camber in the back (unless you installed special rear control arms). A higher offset would take care of the whole problem.

I'm a 2011 swp premium wrx with NO suspension mods and I'm running 255/35 -18. My wheels are rfp1's 18x9.5 et 38. Overall height like 89.3 mm

If I ran a 45 ratio it would climb overall tire height to like 93mm . Just wanted to offer some hard #'s for everyone to observe.. My mm calcs could be off by a 10th or so plus or mins .3

Mods please don't yell or flame me for this comment but I felt it needed to be added.
A lot of members are asking about TPMS and 2 sets of wheels, your local shops (tire)should have the ability to put a "universal" sensor in and copy your oem serial ID to it with a scanner tool. It's not cheap maybe $150-200, but you will have no need for reprogramming every 4-6 months if you live in a snowy climate ...

Hope this helps some... I'm still new so some of my info may be skewed slightly.

Sorry I got off subject

Ok, quick question. I'm looking at getting a set of TE37SL's in 18x8.5 +35. I am on coils, and lowered a little bit. I do a lot of autox and a little road racing when I can. To me the offset is a little low, and I was thinking about going a little wider maybe 9.5 but I don't wanna mess with fenders.

Does anyone think the 8.5 +35 will fit/handle/feel good and look pretty good? I would like those wheels to have a bit of concave.

What does everyone think?

Thanks in advance guys!

Looking for some opinions on what might be causing some steering issues on an '11 STi. Everything is stock except for the wheels and tires.

Tires: Michelin Pilot Alpin Super Sport 245/40/ZR18
Wheels: Enkei GTC01 18x8 ET +48
Using hub-centric centering rings since the bore on the GTC01's is larger than the stock Enkei's.

The issue is that the steering and general ride feel seems really sloppy. Driving straight, the car tends to erratically veer left or right, almost feels like it's toed-out on one side temporarily, and I have to make almost constant steering corrections to adjust. Getting on the throttle will also cause it to veer slightly to one side or another, though at higher speeds, it's less noticeable (at full throttle, it's almost undetectable). There is a small amount of vibration through the steering column both when driving straight (less) and when making turns (more pronounced), especially at lower speeds. Other notes that may be important: there isn't any uneven wear on the tires, when i swap back to the stock wheels+tires, the steering is perfect again, tire pressures equal and verified to be 34psi all around.

First, is anyone else using this same setup or a setup with the same measurements/clearances on the wheels and tires? If so, do you notice any issues in the steering?

Second, does anyone see any problem(s) with the fitment of this setup in general? The stock wheels are Enkei 18x8.5 offset +55 on the same size tires, which ride perfect.

I'm definitely not a fitment expert, but I have a few questions about possible contributing factors. These wheels are less wide than the stock wheels (8.5" - 8" = 0.5" thinner) and the offset is smaller (-7), so the entire wheel will be about 13mm further away from the strut. I'm wondering if this increased clearance could cause any issues. I am thinking no since none of the suspension should be affected by such a change. Next, I really hate the idea of centering rings because I'm leery about how effective they are (I'd rather have bought wheels that didn't require them, but that's another story). Not sure if they could be playing a part here. Last, I've got the same size tire (245/40/18) on a wheel that is 0.5" less wide. Would this extra clearance of the rubber on the wheel affect steering, particularly in cornering? The tire specs allow wheels with widths 8" - 9.5" so it should be fine, but I'm trying not to rule anything out.

As I thought. However, the Rota Grid is only available from the Australian distributor in 18 x 9.5 +38 & they want to charge me a 20% restocking fee to return them! I was thinking of the Rota Force Drift which is only available in 18 x 9 +35 or will I not be much better off?

Mach V Dan , I found a good deal on a set of Enkei RPF1 17x9.5 38et . Is 255/40/17 a bit of a stretch ? Or go with 265/40/17 ?

Sorry I got off subject
Can you please tell me if your rim & tyre protrusion outside the guards is noticeable with your set-up? What is your front camber setting? What tyres are you running?
I have done a trial fit with Rota Grids 18 x 9.5 et+38 rims only & the front protrude by 6-7mm & the rears by 4-5mm with the suspension loaded up (no susenpension mods).
The front protrusion is almost illiminated by increasing the negative camber from 4-1/2 notches on the camber bolt (std setting) 8mm protrusion & turning it clockwise to the 2nd notch down to 3mm protusion. Unsure of what this setting is & if it is useable or if it will cause rapid tire wear?
Your information will be greatly appreciated. Any pics of down the side of your car would be great too. Cheers Roycey

265/40R17 is exactly the same diameter as the stock 235/45R17, and a better fit for the wheel in terms of width. So I'd go with that.

Dan is probably much more versed than I, but to me, I am a laymen but +35 would def require some suspension modifications, as well a pull and roll on the fenders. Details of what exactly I can't say.

As well if your the Aussie who was concerned about the Law enforcement being on you I'd say some where around +40 to get it all tucked in comfortably
But yes there is some protrusion as this what I wanted.
Create a search looking for the parameters you listed and you should see some pics

The 1/2" of width = 12.7mm / 2 (half on the outside, half on the inside) = 6.4mm (I'll just round to 6mm) less stick-out because of the narrower wheel. But the offset is 3mm MORE stick-out. So, +3 - 6 = around 3mm less stick-out with the 18x9 +35 compared to the 18x9.5 +38.

I hardly see anyone running 19" on these cars, I just recently picked up my 13 wrx two weeks ago and came from a lowered tl which would easily fit 19's on springs without any rolling or pulling, I'm interested in getting the new 19" xxr 530 19x8.75 +33 I think. Problems? I'm on stock suspension but eventually want coilovers. And yes I searched

No problems^ Go for it, just do 255/30R19's. Once lowered you will need a rear roll.

A bit of a different question:

I'm picking up a set of used 245/40/17 star specs and am going to grab some cheaper drag wheels to have as a dedicated autocross set. I know i'll need an 8" wheel, but my choices in offset in the style I'm looking at are +47 and +35. I wouldn't anticipate having fitment issues with either of these offsets on my stock suspension, but can anyone provide a recommendation from an aesthetic/performance standpoint?

Thanks.

Couldn't be more wrong. He'll need completely flat roll in the rear, possibly even a roll in the front, if he lowers, it will be absolutely necessary.

Hey guys I'm picking up a set of evo bbs wheels.

They are 8.5 with an offset of +38. Will I need to do any fender rolling if I want to run rce yellows? They drop the car between 10-15mm.

Also what tire size do you recommend? I was thinking about ordering a set of DWs in 255/35/18

So ill definitely need a roll, it's amazing how horrible these cars are when it comes to fitting wheels without rolling, one thing I miss about my tl definitely. I feel like these cars should be easier to incorporate 19's on.
