Need Help sorting out wheel offset so no rubbing APEX EC7s

So I'm looking into purchasing a set of EC7s in the near future. I would like to be slightly more aggressive than my factory wheels and go up half a size in width front and rear. I've searched thru several threads to see what others are running. There are countless very aggressive setups but many of those are running factory suspension. Then there are others who don't seem to mind. My E90M is lowered on swift springs (1.0F/0.7R) with the current factory 220M wheels.

Some months back I tried running 12.5mm spacers and they rubbed heavily in the rear with passengers, and or on dips without passengers. So I would like to run 19" x 9.0/10 F/R EC7s. I think I should be safe with 19 x 10 ET 25 on the rear as this is the ZCP size from the factory. Its the front offset I am having difficulties determining the appropriate sizing. There is limited options for offset on the 19" wheel on APEX's website (ET22 or ET 35). So with that said can anyone comment which of those two offsets would be safe without rubbing? Could I even go to a wider rims front and back without rubbing passengers included?

I have a 2010 E90 with those exact wheels (19x9 et 22 and 19x10 et 25) and a 10mm spacer in the back. While I am not lowered, I specifically asked EAS (who did the install), if there would be an issue if I added the Dinan Stage 1 suspension and moved up to 255/275 PSS tires and they said it wouldn't be an issue.

OP I don't see that you are taking in consideration the tire. You can go with several rim specs but what really is going to determine the rub - no rub situation is the overall diameter of the tire. I have been also wanting to pull the trigger on some Apex specifically on the PS-7 profile 3. I might go with Fronts 19x9.5 et 22 with 265/30/19 and Rear 19x10.5 et 22 with 285/30/19. Maybe a 5mm on the back to try to get the 6mm staggered from factory setting.

Try it and send me a pic of how it looks

I am taking into consideration the tires. But i think wheel offset and rim width play a larger role. If the rim is too wide and offset too aggressive you will rub no matter the tire profile IMO. I would like to have an aggressive race stance without too much fuss. I know 9F"/10"R isn't what you call "aggressive" but i figured I would start there. I am not looking for the "stance" look just an aggressive race car look.

I had folks tell me that 12.5mm spacer with the factory 220M wheels would be ok on the rears with swift springs. But unfortunately that was not the case and it rubbed like hell. So im guessing you haven't lowered the car just yet? Let me know if it works out? Any pictures you can share?

No, haven't lowered it yet.

I was really more concerned about the fronts because the offset is so much more aggressive vs. the rears where I could always take the spacer out or go with a smaller spacer (there are plenty of examples of cars running lowered with 19x10 et 25 wheels).

With the 12.5mm spacer, you were essentially 12.5mm wider than stock vs. my 19x10 et25 with 10mm which is 14mm wider than stock. So based on your experience, I'd probably rub in the rear if I lowered unless I went with a smaller spacer as well.

OP, up front you can run either the 19x9 et22 or the 19x9.5 et22 without any rubbing issues. In the rear, 19x10 et25 is a bolt on fitment which will have plenty of clearance, even after lowering the car with passengers. Our 19x10.5 et22 is an aggressive way to go out back, but still works for many who are into pushing the limits. If you are lowering the car, going with 295 tires, and may have multiple people in the car, negative camber adjustments or fender messaging may be a good idea to prevent rubbing. Here are our two recommendations for 19" EC-7 staggered fitments:

EC-7 GTS Inspired Staggered Setup
Front Wheels: 19x9 et22 - Profile 3 Concavity
Rear Wheels: 19x10 et25 - Profile 3 Concavity
Front Tires: 255/35/19
Rear Tires: 285/30/19 (or 275/35/19)

There were all time levels of excitement within the BMW community when BMW M GmbH announced the M3 GTS; a clubsport version of the e92 M3 which offered a more motorsport focused package for the hardcore enthusiast. Performance modifications were carried out in all departments; interior, exterior, chassis and drivetrain. Specifically the ZCP wheels (F: 19x9 et31 / R: 19x10 et25) were adopted for the GTS in an alternative satin black finish, matched up with wider 255/35/18 front and 285/30/19 rear tires. This staggered setup maximizes rear traction, and with our APEX EC-7’s you too can gain rear end grip while also dropping weight/rotational mass on all four corners. Our EC-7’s weigh in at 22.4 lbs (front) and 23.5 lbs (rear) respectively, saving you approximately 3 lbs per corner over the GTS wheels. You will also notice that our front 19x9” wheel has a superior offset of et22 (as opposed to the GTS et31), making it 8mm more aggressive giving it a flush fitment without the need for spacers. These EC-7’s will also have massive big brake clearance, another testament to the EC-7’s ability to satisfy all customer needs. We know that 285/30/18 rear tires can be quite limited in selection, therefore we also suggest the 275/35/19 which gives the buyer more options to choose from. Again, this staggered fitment is bolt on and go, with no suspension or fender modifications necessary.

EC-7 19x9 et22 - BBK Clearance: Stop-Tech 6 pot 355mm, Stop-Tech 6 pot 380mm, Brembo 6 pot 355mm, Brembo 6 pot 380mm, AP Racing 6 pot 368mm, AP Racing 6 pot 378mm


EC-7 Aggressive Staggered Setup
Front Wheels: 19x9.5 et22 - Profile 3 Concavity
Rear Wheels: 19x10.5 et22 - Profile 3 Concavity
Front Tires: 265/30/19
Rear Tires: 295/30/19

For enthusiasts looking for the most aggressive staggered fitment possible, we would recommend our 19x9.5 et22 application up front, followed by the 19x10.5 et22 application for the rear, wrapped in 265/30/19 and 295/30/19 tires respectively. This concave fitment does a great job filling out the wide fender arches without the need for spacers, giving the E9X M3 a very menacing stance. Depending on the type of tire, and your ride height, rolling the rear fenders may be a good idea to prevent rubbing over bumps and dips in the road.

EC-7 19x9.5 et22 - BBK Clearance: Stop-Tech 6 pot 355mm, Stop-Tech 6 pot 380mm, Brembo 6 pot 355mm, Brembo 6 pot 380mm, AP Racing 6 pot 368mm, AP Racing 6 pot 378mm

Why don't you consider getting EC7's in 18x9/18x10. You can drop tire diameter down by going with a 255/35-18 front/ 275/35-18 rear and have plenty of clearance to avoid rubbing.
Invariably, the problems with 19" wheels/tires are they run a bit tall once you step past OE sizing.
