Thanks Ian. Should I expect any rubbing given I'm lowered slightly on Eibach springs. With 295, I don't think so, but would love your thoughts based on what you have seen.

You shouldn't see any rubbing with that rear setup. Hoosiers can tend to run a bit wide, but with a 295/30-19 you should be alright even with lowering springs. At stock ride height a 305/30-19 with a 19x11" ET44 is a direct fit with Michelin PS4S, so the 295 Hoosiers and slight lowering should work ok.

And the Eibach's are super conservative, I believe only 0.2" drop in rear.

Will It Rub??

Hey! Before I order tires I’d like to confirm. Will the standard staggered track config rub if using lowering springs? I don’t want to pull fenders or mess with the fender liner.

Looking at:

18x10 ET25 SM-10
275/35-18 R888R

18x11 ET44 SM-10
305/35-18 R888R

No wheel spacers
Lowering springs - Swift Springs Sport Spec-R

Thanks!!

Hello!

This fitment is typically a direct fit, however with the aggressive tire compound being used along with lowering springs, the front fitment will be close without any additional negative camber. The rear should be a direct fit as we have even seen people run 315/30-18 street compounds without any fender or camber modifications.

Most likely you will be alright, but there is a slight chance you may experience some rubbing up front with the car loaded with passengers or over certain larger dips/bumps.

Perfect. I just installed camber plates up front (should have mentioned that). So I’ll be able to set additional negative camber.

Thank you!

Awesome, you should be good to go in that case. Post up some pictures once you get them installed!

I just got a set of SM10 wheels. 19x10 ET25 front and 19x11 ET44 rear. I'm very happy with the look and fitment and the customer service was fantastic.

If I wanted to run 265/40/18 front and 285/40/19 rear tires, which wheel fitment do I need? I’m currently looking at these tires for my OEM 513m wheels but was also considering apex wheels.

Hi there,

I'm assuming that the 285/40-19 size you listed was a typo and that you would want to run a 285/40-18, considering the OEM 513M wheels have 18" diameters front and rear.

If that is the case, I would recommend the following fitment for your application:

Front: 18x9.5" ET22 with 265/40-18 tires
Rear: 18x11" ET44 with 285/40-18 tires
Brake clearance: SB
Available in EC-7, FL-5, and SM-10 designs.

While the tire sizes you listed are a touch on the taller side, this setup should provide a direct fit on a stock F8X. If you are interested in running alternative tire sizes, these wheels can support up to a 275/35-18 front and a 305/35-18 rear as a complete direct fit on a stock car.

If you have any additional questions, please do not hesitate to reach out!

-Geirsen

Perfect! Yes, sorry that was a typo, as both front and back are 18 inch. I like running the 40 profile tires for the side profile and comfort. Do you think there would be a change in comfort if I run the tires on my OEM 513m wheels and your wider Apex setup that you mention above? I'm assuming going from the OEM 513m front 9 inch to your 9.5 in and rear OEM 513m 10 inch to 11inch Apex setup will stretch the side profile so it will not be as fat and comfortable? Or am I just over thinking it?

Oh and can I possibly run the 265/40/18 front tires on your 18x10et25 wheels? I have about -2.7 camber in the front and -2 in the rear running the Bilstein b16 coilovers

The aspect ratio for tires is a percentage of the tire width, so while our recommended 275/35-18 and 305/35-18 tire sizes utilize a shorter "35" aspect ratio, the additional width makes for them to be quite close to the OEM rolling diameters. With so many variables to consider, such as specific tire compound, suspension setup, etc, it is difficult to say if there will be a noticeable difference in ride comfort and compliance between both tire setups. However, those sizes will be slightly more stretched on our 10" and 11" wheels.

While you can technically run the 265/40-18 on a 18x10" ET25, I recommended the 18x9.5" ET22, as that wheel size will fit the 265/40-18 a bit better. Also, with the 18x10" ET25, you will need 5mm front spacers to clear your B16 coilovers. Whereas with the 18x9.5" ET22, you will not need any spacers to clear.

If you have any additional questions, please do not hesitate to reach out!

Got it. I don't think I want that much of a stretch, so would it be advisable to go with a 18x10et25 for my rear 285/40/18 tires? Instead of the 18x11?

I would opt for the 18x11" ET44 if you plan on running a more aggressive track-focused tire compound, as those tires can run a bit wider than the sizing suggests. However, if you plan to run a more street-focused tire, the 18x10" ET25 might be a more ideal option if you want to avoid any significant tire stretch.

Got it!

I don't really track my car as much as I used to, but mainly DD and weekend canyons with maybe 1-2 track days a year. I used to go about 4 times a month but then I got married and had kids soooooo..haha

Thus why I want fatter side profile tires for comfort.

Just picked up a set of EC-7s wrapped with Nankang AR1s and I'm loving the look of these!

Front:
18x10 +25 with 275/35/18

Rear:
18x11 +44 with 315/30/18

From my understanding, the fronts clear stock suspension with lowering springs? I currently have EMD springs which I feel are too low, but these seem to clear both front and back. Anyone running a similar setup? Haven't had a chance to drive with them yet since it's been raining.

Looks amazing!! That setup should clear just fine with OEM shocks and lowering springs as long as the lowering isn't way too extreme. The issue with front suspension clearance is typically only seen with coil-overs that limit inner tire clearance like KW Variants, Bilstein PSS10, and a few others.

Ian, would you consider the Bilstein B16 Damptronic kit to be similarly limiting inner clearance?

From the looks of the B16 Damptronic kit, it seems like clearance would be very similar to the PSS10. If you were to run an 18 or 19x10" ET25 front wheel with a 275 tire, you would likely need a 5mm front spacer to provide adequate clearance.

Another options is to instead go with an 18 or 19x9.5" ET22 which provides better clearance and will not require a spacer. With this wheel, you could still run a 275 front tire.

Hello,

I recently purchased 19x10 and 19x11 SM-10 wheels and currently run 265x35 front and 295x30 rear Hoosier R7s. Very happy with this setup, it works great, no rubbing. Thanks to Ian at Apex who helped me get the figment right.

I want to try Toyo Proxes RR next. They only seem to come in 235x35 or 295x30 in the 19 inch sizes. Question - would 295x30 fit the front of my stock suspension F80 lowered on Eibach euro V1 with the 19x10 ET25 SM-10 wheels? If so, I would run the 295 square setup though rear wheels are 19x11.

Hello,

Glad to see you got your wheels, they look fantastic on your car! The 295/30-19 is a bit too wide for a 10" wheel and will lack sufficient sidewall support for track use. You will also likely encounter some issues with rubbing on the fender without some serious negative camber. The widest I would recommend up front would be a 285/30-19 and even that would likely require a bit of negative camber. A 275/30-19 would be about the largest you can run without further modifications like camber plates and a custom alignment.

It is a shame that tire choice is so limited in the 19" sizes.

-Ian
