Always liked the rear 1/4 shots on the M cars with the fatter stance. I ordered some 20mm spacers for the rear and 15mm for the front. Luckily the 20mm were backordered and I got the 15mm first. I put them on the front and they were just too much for my taste. They leveled the wheels out nicely, but from the front they just showed too much tire for me.
Moved them to the back and they looked perfect to me. Going to run with it like that for now and maybe add some thinner ones up front if I think it needs it. I like the way it looks right now myself.
Anyway, thought I'd share.
