Just installed my new track setup. Couple things was being considered since we will use this car as a test bed for our new track suspension development, when; the ability to rotate wheels for even wear, and no modifications done to the fenders to fit the wheels.

Apex suggests 19x9 +25 w/ 265/35/19 tires for its square setup but I opted to take a gamble and try fitting their 19x9.5 +25 with Falken RT660 in 265/35/19 to get a better stance.

Currently it’s lowers on MSS Adjustable Springs and stock alignment, and I haven’t had any issues with rubbing. Next week I will take it in for track alignment and corner balance so clearance and turning from Lock to Lock might change, so I’ll have to report back on that.

Let me know what y’all think, any thought and suggestions are appreciated!

This is fantastic, I actually had a testfit of these same wheels scheduled for a ZTK car combined with a brake scan but you beat us to it. Once it's aligned I'd like to hear your thoughts on rear tire to rear fender liner clearances and the clearances between the inner tire edge and the front struts/spring assembly. Those are the 2 pain points I've been concerned about with this fitment.

Also, that caliper clearance is pretty tight! Likely not an issue but debris like rocks or something might get caught between the front caliper and spokes and scratch up both components. Maybe a small spacer like 3mm would build that margin back up if the front can support that change.

Thanks for the tip Tom!

And yes you guys are welcome to use the photos.

Best looking aftermarket wheel/tire setup I've seen yet!

With BMW's ZTK package coming with 9.5 on 255, I'm surprised Apex recommends 265 on a 9.

I wonder if this is because most people do not have the ZTK package with the 4mm fender flares, thus keeping the fitment for the majority a little safer?

[Stradale Design]

Alignment done
-1.5 degree front camber 0.09 toe
-2.5 degree rear camber 0.15 toe

Now the rear clears with no issues. The alignment also helped the car feel lighter compared to the stock settings.

Correct, the 265 is one of the 3 sizes we list for 9" square and of the 3 probably the one I'd recommend least often. 245/40-19 or 255/35-19 are what I recommend to most on the phone, 265/35-19 makes sense if you're running an all season or summer tire who's true width runs a bit narrower than the listed size.

Once we do a bit more testing with the 9.5 ET25 as shown here, it'll go onto the guide with 265s but I want to check clearances on stock cars before trying it or recommending it to unsuspecting street customers looking for easy fitment.

With 200TW tires that run as wide as the RT660s, the 9.5 is definitely a better width of wheel.

Nice! I'm surprised you got that much range out of the stock suspension in the rear! That was just with MSS springs and the OE eccentric bolt?

Assuming you are talking about my car, I’m excited to hear that these were the wheels getting prepped for our January schedule.

Will be looking forward to it.

Yep, it should involve wheels in this size along with the brake scan. looking forward to bringing you in!

I really like this fitment. Possibly my favorite so far.

Anyone know what the factory alignment specs are?

How did you go about getting the negative camber, have you installed top mounts (camber adjusters), also would you not prefer 18’s for the track set-up and leave the 19s for road.

The factory camber range is pretty large so we’re able to get a lot of camber in the rear.

I would have preferred 18inch wheels for the track but due to the lack of wheel choices in 5x112 we chose to go with 19inch. In addition, this car is no means a dedicated track car so putting 18inch wheels with 35 series tires on a relatively big car looks weird IMO 🙂

Thanks, how much camber were you able to achieve on the fronts

This information is great!! thank you for posting it

[shonseb]

I did a thing....

Stradale Design

Thanks for posting the specs and dialing in the fitment. I was initially going to go staggered, but after seeing this thread I changed my order. I would have initially went square but I wasn't sure about fitment and I didn't want to run spacers. Now rotating these wheels for track use now should be easy. 👍🏾

Nice!! Looking forward to seeing your setup!

[Jack@AUTOID]

Gonna try and get same camber set up as you guys with my MSS. Looks great guys. Nice work.

How would this fitment work with 19x9.5 +20?

Can I run the 19x9.5 et25 with 255/35 or 265/35 on stock suspension without any clearance issues? (I don't plan on modifying the suspension)

That setup might be hard to fit without any kind of camber adjustment for the front as these wheels are an aggressive fit. Although the OEM suspension gives you the most clearance, you still may have to run a spacer to help clear. Here is a car running that setup:

ApexWheels thank you for the response! Last few questions if you don’t mind!

Is 19x9 et25 255/35 the widest I can go without any additional modifications to suspension? More like a plug and go.

https://apexwheels.com/gallery/bmw/2...in-bronze-1315

Is this running any spacers up front or modification done? This was the set up I was thinking about originally.
