I am considering spacers with 15mm Front/ 12mm Rear coz they're the most common measurement recommended by everyone in this forum for a stock e92M3 with ZCP. But when I took measurement, there's barely any space left between the well and tire-lip when I measured as shown below. There's about 3-4mm space for the front and barely 3mm for the rear. Am I doing the correct measurement here? I was hoping to have no rubbing. Should I stick to 15/12? Appreciate your insights
Thanks in advance
