If you wanted wheel widths the best suit your current tire sizes, we would recommend the following staggered fitment which replicates the OEM ZCP/GTS wheel specs:
Front: 19x9" ET28 with 255/35-19 tires
Rear: 19x10" ET25 with 275/35-19 tires- Direct fit.
- Available in ARC-8, EC-7, and SM-10 designs
- 285/30-19 rear tires can also be used to mirror M3 GTS tire fitment.
- OEM 245/35-19 front and 265/35-19 rear tires can also be used as a direct fit.
- This fitment is 1/2" wider all around than the OEM 19" Style 220 wheels, meaning you can either reuse the stock tires or go wider. The widths and offsets mirror those of the OEM Competition Package/GTS wheels.
You will not need to use any spacers with the fitment as listed above. This is a direct, drama-free fitment!
If you are looking for something a bit more aggressive (flush), while still maintaining a spacer free fit, we would recommend the following setup. You can reuse your current tires until they wear out, but they will be a touch stretched.
Front: 19x9.5" ET22 with 265/30-19 tires
Rear: 19x10.5" ET22 with 285/30-19 tires- Direct fit.
- Available in ARC-8, EC-7, and SM-10 designs
- Rear 295/30-19 tires can be used but may require rolled fenders to prevent rubbing.
We have worked hard to design an entire fitment guide that details every fitment on offer for the M3 chassis, including the two fitments listed above!
The fitment guide for your chassis can be found here:

These guides are an overview of every fitment we offer for this chassis. I would highly recommend taking a look at this guide as it should answer most, if not all, of your questions.
I hope this helps! 
Best,

I bought an e90 m3 ZCP stock suspension no spacer car that apparently came with Apex EC-7 19x10 front with 255/35/19 tires and 19x10.5 rear with 285/30/19 tires.
I want to know if I can change the rear tires to 275/35/19 to reduce the fender gap a bit?
Car is for street driving rather than track. If 275/35 rear won't work, what would you recommend?
