I've always needed this kind of explanation and never found it till I watched this video of course. So thank you very much I needed someone that was very clear and shown examples and other helpful info.

What size would you recommend in a 18x9.5 rim with factory suspension? I don’t want to lower it rather fill in the fender gaps a bit.

[jasoncleveland]

Remember adding positive caster will cause the wheel to gain negative camber as the suspension compresses. Can run less camber, with the overall same handing and suspension characteristics and not go through tires as fast.

Excellent! Came back here once more before I purchase.

255.35.18 - Got it!

9x5 +38 - Got it!

Springs with lowest drop??

Eibach is popular near me.

TIA

Appreciate the videos and support!

In case anyone is looking for some info.

I'm running 18x9.5 +38 (TE37SL) with 265/35r18 -- rubs in the rear, and I don't have my fenders rolled. Had to lift the rear up 1/2 inch and it still rubs. Plan on switching to 255/35

So I had a steal of a deal on some Toyo Proxes 4 Plus. They're 245/45/18. I put them on my stock wheels and they ride really good, no rubbing. And, I feel like they fill the wheel well more. No one really talks about running 45 walls on STI, not sure why. Eventually, I want to lower, and go for a wider tire. 265/35/18 seems like a perfect setup.

What is the inset and outset clearances from a stock sti wheel and tire?
From what I gather from the video, 17-20 mm outset clearance stock based on both your spacer (20mm) and your recommended offset of +38 on a new wheel set.
The only inference I can make on inset is there isn't much of it, is there at least 8mm?
Around 30mm total play?

Trying to do the mental gymnastics to find various solutions that would fit my desired effect. No mod, no rub, flush, etc. And having the safe space on each side helps a lot ;)

Hey Subispeed 👋 super late to the video but I’m a recent WRX owner and have been following your videos and shopping online. At the end of the video you gave a recommendation of tire size for 9.5 width wheels with for lowering springs and then for Coilovers. I was wondering what you’re recommendation for tire size on stock suspension using 18x9.5 wheels is? Or if you didn’t recommend using 9.5 width wheels on stock suspension all together?

Geez where is the love for 17in rim videos?

[khurelkhuutsagaantsooj]

I was looking for backspace measurement for STI brembo clearance. Although they spoke design was mentioned, i could've used some numbers like "4 pot front calipers need XX milimeters/inches to fit properly" etc... dissapointed!

[EVORS]

on my '15 Sti im running RCE Black springs only .40" drop(ride nicer!) and 18/9.5+38 wheel and wrapped w 275/35/18 NO RUB WHATSOEVER yes ...Two Seventy Five mm wide no rub...it fits al day long. DONT Believe people that say 265 is widest you can go lol

[aneurysmgarage]

What would you recommend for a 2018 Subaru wrx base with stock suspension running 18x9.5 +38 ?

[Heetcat]

so 255/35/18 18x9.5 + 38 offset would be best setup for wrx with stock suspension?

[letruong]

What tire size do you recommend for wheel size 18x9.5+38? This is for a flush look on a 2019 WRX Limited with stock suspensions.

[YourQuietSounds]

This video is perfect. It explains everything you need to know. Thanks

[rexnflex]

I know you recommend 255/35/18 on 9.5 +38 can't afford wheels and tires at the same time. Will stock tires work in that wheel size if I buy the wheels before me tires. I want safe reliable set up.

[savagestevieb]

I have the 2020 Subaru WRX STI, Series White. Which comes with the 19 x 8.5 wheels and the 245/ 35 tires.

I wanted a wider look and was looking into a wider set up of tires without rolling fenders.

Question: what do you recommend for tire size if I want to keep my stock wheels? Do you also recommend using spacers?

[bw]

Whats the widest setup that doesn't stick out of the body work when facing the car front on. I legally can't drive with any wheels that stick out. Does an 18X9.5 +38 sit flush or is it wider then the body?

[osmanabigangbang]

I just got 18x9, 5 +38 offset and it hits the breaks on the front. Im sad... (2016 STI)

[rhobee]

Hi for a 2017 wrx - thinking of picking up a 18x9.5 et40 on 265/35s. No plans on dropping for now. Any experience on rubbing for this?
