Looked @ M-Tech..... didn't do it for me @ all!! Way too many M3 wannabees out there with M-Tech I or II bumper kits. My actual preference is the Reiger Front lip and rear spoiler, but, 2nd fav is the Hamann and got all the 4 pieces (spoiler, side skirts and rear spoiler) for around $200 total. The deals were too good to refuse, so Hamann it is!! May swap out pieces over time, not sure. ACS look also doesn't do it for me either; way too in your face!.....
Still need to polish pieces, thats why they aren't looking as shiny as the rest of the paint. Have 3 clear costs, but need to use some rubbing compund on them theis weekend to bring out the shine. Because of the colder temps, wanted to give them more time to fully cure before buffing them.
