Nice conversion! Now that you have M3 front bumper, you should put some cool M3 OEM 219M wheels in gunmetal to accentuate it. Check out this site:
I have the same wheels and live close to you if you want to get together to look at them on SGM in person!
I know a lot of guys who put scoops in place of mesh on their M3 rep bumpers. You might want to consider that, too.
