Hi the APEX Team and everyone, I'm considering a new set of APEX wheels and 200TW tires for the upcoming track day season. My F80 M3 has CCB and is running KW Clubsport 2 Way suspension (see attached photos for the ride height). The car is running -3.1 and -2.2 camber front and rear, respectively. Both front and rear fender inner liners are having a lot of rubbing under heavy compression at the track. My concern is with the new setup will I have less or even more rubbing for track use (lapping days).

Current setup:
F: 19" x 9.5" ET22 | 265/35-19 Michelin Cup 2 (non-Star) | Overall Diameter: 26.3" | Tread Width: 9.3"
R: 20" x 10.5" ET34 | 285/30-20 Michelin Cup 2 (Star) | Overall Diameter: 26.8" | Tread Width: 10.3"

Target new setup:
F: 19" x 9.5" ET22 | 275/30-19 Falkens RT660 | Overall Diameter: 25.6" | Tread Width: 10.2"
R: 19" x 11" ET43 | 305/30-19 Falkens RT660 | Overall Diameter: 26.3" | Tread Width: 11.4"

While the target new setup is definitely wider, the overall diameters are smaller (and that the rear wheels have different offsets although wider).

Based on APEX's fitment guide, the target new setup is APEX's Staff Pick and is a direct fit meaning no modification is required as the Hardcore Track / Race Fitment. Moreover, my car is running (not a lot) more negative camber than is suggested as required by APEX. However, given the rubbing to the front and rear fender inner liners with my current setup, I wonder if I can expect less or more rubbing with the new setup if the ride height and camber angles remain unchanged. Your help or experience with a similar wheel and tire setup will be much appreciated.

Thanks for reaching out and nice looking M3! As you mentioned, most of the rubbing is likely due to the height of the tires. While we have seen a 265/35-19 used in front without issue, if running a more aggressive compound or a tire model that runs extra wide, there can be an issue. Your ride height and compression settings will also have an impact and with hard track use you can quickly see the issue. In back it is likely a combination of a bit too tall of a tire along with a pretty low offset for a 10.5" wheel.

With the fitment you are considering and tire sizes mentioned, I don't foresee any issues at all even with a 200tw tire if you keep your alignment specs with the added negative camber. This fitment is a direct fit with most street tires and the camber will help to tuck in the wider 200tw compound. With the higher rear offset and shorter rolling diameter, you'll have a great rub free track fitment.

Let me know if you have any questions.

Many thanks Ian.

With my current setup, the tire model and size are essentially the same as M4 GTS and M3/4 CS so my understanding is that the overall diameter is the same as stock, maybe on the tall side comparing with non-Comp M3/M4.

I also understand from some other posts that M3 F80 has less room inside the front fenders comparing with M4 F82.

When you stated "I don't foresee any issues at all even with a 200tw tire if you keep your alignment specs with the added negative camber", did you mean you don't foresee any rubbing both front and rear with the target new setup if my current ride height and camber angles (F: -3.1; R: -2.2) remain unchanged?

I definitely hope the shorter overall diameter of the target new setup (F: -0.7"; R: -0.5") would be more than enough to compensate its wider width (F: +0.9"; R: +1.1") (remarks: and the higher rear offset).

Often times when moving to a wider wheel and tire with a lower offset, a slightly shorter tire will be needed to compensate. Even if the current setup is the same diameter as the M4 GTS fitment, the extra width and lower offset cause an issue.

Yes the target new setup should work just fine without any rubbing with your current alignment specs. The shorter tire should alleviate the rubbing and the negative camber you have will provide added insurance against any possible fender rub.

Hi Ian, further to my previous question, I'm wondering if the wider [COLOR="Green"]19x10" ET25[/COLOR] FRONT wheels fit as well (e.g. better handling, more flexibility to go with even wider tires in the future).

With these wider FRONT wheels:
I. I understand that I will need to run 3-5mm spacers at the front too clear my KW Clubsport
II. The 0.5" wider wheels will increase the tire section width by ~0.2"
III. The tire tread width will probably remain unchanged

Given my clearance concern (the [COLOR="Red"]current setup[/COLOR] has a lot of rubbing with the inner fender liners under compression load at the track) is with the tires (I. would have address all clearance concern with the wheels), does it mean the wider [COLOR="Green"]19x10" ET25[/COLOR] FRONT wheels should not reduce any clearance?

Hello! The 19x10" ET25 certainly can be used and will provide better side wall support for a 275 width tire. As you mentioned, you will need a 5mm spacer for inner clearance which will result in an effective offset of ET20. This will be pretty darn aggressive and you will likely need to add some additional negative camber to ensure a rub free fitment. If you're willing to add enough camber to make it work, then this setup with the 19x10" ET25 up front can be used.

Many thanks Ian. I'm considering to install some lower control arms now to increase front negative camber from current -3.1 to about -3.8. As with the [COLOR="Red"]current setup[/COLOR] the rubbing to the inner fender liners is mostly against the middle and outside shoulders of the tires, hence I would like to avoid (if possible) to move the wheels outwards with the [COLOR="SeaGreen"]target new setup[/COLOR], hence, will 3mm spacers (as per the image below, the 3mm spacer will mean the middle point of the wheel+tire remains the same comparing with my [COLOR="Red"]current setup[/COLOR]) be enough to clear the KW Clubsport coilover?

My thinking process is that since the rubbing with my [COLOR="Red"]current setup[/COLOR] is with the tires only, with the [COLOR="Green"]target new setup[/COLOR] the wider 19x10" should not introduce more rubbing comparing with the narrower 19x9.5" if the offset is very similar and as long as it's still clear my coilover. Please correct me if I am mistaken.

Unfortunately it's really tough to give exact answers regarding the camber spec needed and spacer thickness as it will depend on a number of factors. Some tires run wider than others in a given size and your spring configuration and ride height will also play a role in determining the position of your lower height adjuster and how much inner clearance is needed.

Most likely a 3mm spacer will not be sufficient with the 19x10" ET25 and a 275/30-19 track tire due to the KW coilovers. It is however hard to guess and really just requires in person test fitting.

Regarding the lower control arms, unfortunately camber gained there does not help with fender clearance as you are essentially moving the bottom of the tire outward rather than tucking the top in (under the fender lip).

I recommend getting in touch via a phone call at (925) 264-6438. Our BMW expert Tom can walk you through all these details and more to ensure you get the perfect setup for your application.

Hi! I currently am running stock 19" 437Ms with 255/35 and 275/35 PSS tires with 12mm front and 15mm rear spacers.

I want to get the OEM+ recommended 19" setup on EC-7s. Just wondering with the same tire setup if it would still be flush? Planning to run A/S 4 tires in Seattle area and don't want to compromise traction.

Side question: Is there an option where I wouldn't need spacers and still be flush? Want to delete spacers to add some sort of wheel lock.

Thanks for the question. I assume you are asking about our 19x9 ET30 front // 19x10 ET25 rear setup?

Compared to the stock 437M offsets (19x9 ET29 front // 19x10 ET40 Rear) Our front wheels will sit in nearly the same place as the 437M while our rear 19x10 ET25 wheel will be 15mm more aggressive with no spacers. If you stuck with the 9" front EC-7, you would need spacers to get a flush fit.

One alternative would be to use our 19x9.5 ET22 wheel up front instead. This wheel will be 14.4mm more aggressive on the front than the 19x9 ET30s with no spacers required and should allow you to run the 255/35-19s as a direct fit. This combined with the 19x10 ET25 in the rear is going to be your best option from our lineup for a flush spacer-free fitment.

Sounds good! I'll look into this setup. Would it still be flush if i went 19x9.5 ET22 in the rear? Thinking of maybe a square setup as an alternative option. Or would i need to go 19x9.5 ET25.

19x9.5 ET22 would be fairly flush (I believe the outer face of that wheel would sit 3.4mm inward compared to the 19x10 ET25 in the rear). 19x9.5 ET25 is an offset that isn't offered on our 5x120 BMW wheels that I know of.
