Default Toe adjustment arms yay or nay

Hey guys I did a search but couldnít find the direct answer so thought Iíd ask here as Iím about to put my Advan GT 18x9.5 +45s on.
Iím going purchase rear lower control arms so I can set my rear camber as many members here have done but my question is, has anyone installed the rear toe arms for adjustment? Iím looking for about 1.5-2 inch drop and want to know if it will throw out the rear toe much or any at all? https://www.flickr.com/gp/[email protected]/2252S2

More adjustment options are always welcomed, but not necessarily required in your situation. I doubt you'll see any toe spec beyond what the stock adjustment bolts can compensate for.

With that said, if it were me, I'd grab this kit and call it a day:

Gents and gals,

From what I've been reading, it seems that for riding on a stock suspension and no spacers, the max size I can manage on my 2017 WRX to have the most flush look (without going to 19in wheels) is an 18x9.5 et38, correct?

Due to the cost of 255 or 265 tires being so much more than 235 or 245 for the Pilot 4S, I was considering just going up to 18x8.5 instead of 9.5. What I'm trying to figure out is the correct wheel offset for the 8.5in wheel width to give me the most flush look I can manage. Based on this calculator: https://www.1010tires.com/Tools/Whee...et-Calculator# it looks as though an offset of 50mm is the way to go. Is this correct?

+50 from +55 would be the right direction, but I doubt by enough to give you what you apparently want.

The quick and dirty guideline would be to measure how far out you think you want the wheels to sit. Subtract that number, converting to mm as necessary, from 55. Do this for the front and the rear and use the higher answer. IOW, if you'd want to move the front wheels out 20mm and the rears only 15mm, you'd choose wheels with +40 offset.

Beyond that, you'd need a software or an app that can overlay the two wheel and tire outlines that you want to compare. I've got one in Excel that plots sidewall shapes better than most, but unfortunately I can't upload pictures here by any of the same ways I use everywhere else.



Kind of a side note, but I'm just not understanding the appeal of "flush" with OE-width wheels. Is it to fool people into thinking the car is running wider wheels than it really has? Or is it something else?

18x8.5 +55 is the stock 18" size and they are fairly tucked.
For reference, 18x9 +40 on stock 245/40/18. Mild drop on springs.

This is a stock wheel (18x8.5 +55) at stock height w 20 mm spacer. To achieve this look without a spacer, it would be an 18x8.5 +35 wheel.

This was mine looks like when I still had the 25MM spacers on both front rear on the stock wheel.

What I'm not following is why people aren't taking advantage of such a perfect opportunity to add a little performance at the same time. Once you step away from using the actual OE wheels, the choice to go wider than OE doesn't even have to cost much more.

So because I am an engineer, I have access to SolidWorks, so I managed to calculate out what my offset should be. Basing my information off of the 18x9.5 +38 being the most flush, I believe that an 18x8.5 +26 will be the most flush look I can get without pissing away money on a fat tire.

I still have yet to measure out the distance from wheel to fender to finalize and confirm this information, so this is mostly theoretical.

Good luck finding a 18x8.5 wheel with that offset in the real world...

Yeah I may have to substitute with some wheel spacers, which is fine

I didnít go with a wider wheel/tire because itís my daily. I switched to all seasons because I live in Texas and only drive 8 miles total each day so 2 sets seemed like a waste. They will probably rot before they wear out. Wider tires are more like to hydroplane and will perform worse in the rare case that I do drive in snow. Wider tires, at least for all seasons, are more expensive and less readily available. Iím not exceeding the current grip levels so it only seemed like negatives to go up a tire size.

29mm (to effectively go from +55 down to +26) is going to be a job for custom machining. And longer studs.

Easy mental math . . . maintaining the outer flange location of a 9.5" wide wheel with +38 offset in an 8.5" wide wheel needs the offset to go down by half of the 1" reduction in width, or 12.7mm.

Fair enough . . . though the OE 245/40-18 is tire industry approved for fitment on wheels out to 9.5" wide, so you actually wouldn't have to get new tires. Not for technical reasons anyway.

Maybe this has been covered in previous posts. I'm amazed at how many redundant posts there are regarding will this fit or will that fit? Will this rub or will that rub? What tire size do you recommend with this size wheel? But, what are the general driving impressions when you guys have gone with a wider wheel and tire combo? How has your car changed by going to something like a 18x9.5 et 38 with 255/35 or 265/35 tires? It seems most people are concerned with aesthetics and not actually posting about driving impressions with different set ups. Geometry changes greatly with each wheel and tire setup and corresponding alignment specs. Sure, wider wheels and lower offsets fill the fender well for nicer aesthetics. But, at what cost? Is there anyone that has considered how you have changed the handling dynamics of a car that has been engineered by STI to handle great from the factory?

I bring this up because I too fell trap to the aesthetics. I put 20mm spacers on my stock BBS Limited wheels and it dramatically changed the way the car behaved. The steering feel became heavier, the car felt twitchy upon corner exit acceleration, and steering response felt slow (due to the widened steering ratio change). It may have looked cooler, but I felt the trade off wasn't worth the scrub ratio being that much off.

Fair enough points and I agree that a 9.5" wheel is probably unnecessary on most cars but the thread is the "wheel and tire FITMENT thread". So the questions are about fitment of various wheel and tire sizes.
On a daily, I doubt most will notice the handling changes from wide wheels. Not enough to outweigh the astectics anyways.
Lastly, I've never had spacers but I don't think the effect of spacers versus wide wheels is a direct comparison. You pushed the stock 8.5 wheel out 20mm. A 9.5" puts some back under the car so it may not have the same feel.

You're right that this is a wheel fitment thread and I get that. I figured this would be a good thread to bring the topic of handling up since it is regarding various wheel set ups. You're also right that by adding spacers to OEM wheels will behave differently than wider wheels with lower offsets. That's exactly why I bring this up. Does installing a wider wheel compensate for the lower offset that most people choose when they go to a 9" or 9.5" wheel?

Yes, the inner clearance is about the same. Example below of the most common wheel size.
