Since you already have all of the trim painted, you should check out the AC Schnitzer kit (you would only need front & rear bumper covers), IMO it looks awesome with everything painted the same color (and I generally prefer the contrast of the oem black plastic). When it comes to painted trim I would go with the ACS, I like the 4.8 in its oem form, but thats just my .02, in the end do what you like you will be driving it afterall.
