No bigger brakes kits are out for these yet... but 24" does not make a crazy difference in braking. I tow a 21' ski boat and it still stops no problem with the wheels.
THe GMC emblem is simple to get off - get a heat gun (or even a high powered hair dryer and some fishing line - heat up the glue underneath and use the fishing line to 'saw' through it. After its off use a solvent of some type to get the residue off. Careful, that double sided tape that holds the emblem on gets very hot with a heat gun.
The grille is a Trex (www.trexbillet.com
) mesh .. its an overlay, but very good fit. It comes in polished stainless but I powdercoated it black just to make the gmc emblem pop a bit more. The emblem is from trex also and it bolts right in, very easy.
The rims ... well I really didn't have to pay for them. I work for MHT. They would retail probably in the $8500-9000 range.
The taillights are tinted with a mix of black paint and clear coat... not sure exactly, I just took them out and gave them to the local body shop that does it for me. I think I should have gone darker but at least they still appear to be legal.. looks wicked at night.
The HIDs are in the standard housing, yes. Install... medium difficulty, there's no access behind the headlights from the top. To make it easy take the inner wheel liner out complete... I just pulled off the 7 screws at the front, cranked the wheel one way, and peeled the wheel well back to get access. I got them locally from a guy I know..
Sidewall is still decent.. I have a 3.25" sidewall still, plenty of tire to get through potholes. Obviously I'm a little more careful when I drive, but I have hit the odd one in the past and never had a low pro tire blow (knock on wood!). I've always had big wheels/low pros on every vehicle I've owned. Powdercoat is pretty solid... I'm not worried about rocks or anything chipping it up. If a rock is going to ding powdercoat it would have dinged chrome either way.. paint on the other hand is a different story.
