ApexWheels wroteThank you for the detailed response, much appreciated.Hey! This setup can work on an E90 M3 and can give you an aggressive rear tire. Here is what we say:
Wheels:
-Front Wheel Size: 18x10" ET25
-Rear Wheel Size: 18x11" ET44
5mm front spacers may be required for certain aftermarket suspensions.
Tires:
-Front Tire Size: 275/35-18
-Rear Tire Size: 305/35-18
-May require rolled rear fenders to prevent rubbing.
-Many drivers remove the rear fender liners to avoid contact.
-295/35-18 rear tires may also be used.
This is the most aggressive staggered fitment out of the lineup, and would typically be reserved for either a serious track/race car or a car with a substantial bump in power (supercharged / stroker). The driver's goal is to maximize wheel and tire width under the front and rear fenders, and enthusiasts running slicks may even opt for a 10.5" front wheel for superior sidewall support. We recommend 12mm or 15mm spacers to clear the subframe, however the spacer requirement varies due to differences in tire brand and alignment settings from car to car. Using these spacers results in an effective offset of ET32 (with 12mm spacers) or ET29 (with 15mm spacers). These higher offsets provide greater fender clearance compared to
our 18x11" ET25.
Even with spacers, the rear tires may still make contact with the subframe under full droop, such as on a lift. The front tires may lightly scrub the inner fender liners at full lock or at particular steering angles, and most of the time things will "self clear" over time (a little divot will form in the plastic liner). This is considered par for the course with wider wheels and tires, and enthusiasts shouldn't worry, as no major damage will come from this.

Could I go abit conservative with the tyres to be on the "safe side?" So i don't need to roll the fenders?
Such as 265/35/18 on the front and 295/30/18 on the rear?
Apart from spacers, any other modification required?
I am currently on stock suspension if that changes things?
