I am going through the same thought process.. I am ready for some new wheels and tires. With 285's HOW MUCH of the air dam does one have to trim? Can someone show me a pic of the air dam that has been trimmed as opposed to removed?

www.wheelpros.com has a lot of cool wheels
www.americanracing.com does too

so please tell, how much trimming will I have to do? It seems as though I would have to do the trimming before the tires were installed, and that would be a pain (in fear of trimming too much). Those that have had 285's put on, did you simply drive home, and THEN trim? Did it rub that bad? Please advise..Or should a person simply go with a 255 and avoid all of that?
Thanks
