Welcome Hono, and congrats on your car. Post some pics of your ride in the
Roll Call thread. I agree somewhat about the rear bumper insert. But I think the SAP rear bumber only looks good on a black car. On other colors it makes the rear end look bigger than it really is. I didn't like the gray, so I had my insert panited black. It's a better contrast with brighter colors like my Yellow Jacket, and it tones down the lettering. As for the mirror, lots of guys are going with the Gentex mirror(on my christmas list

) Here's a thread on LS1GTO.com about it
http://www.ls1gto.com/forums/showthread.php?t=51560. There are good links in this thread to install procedures. I don't mind my stock 17" wheels although they are a pain in the butt to clean. I'm planning on eventually getting some custom 18" Rally IIs for mine.
