<FONT face="Comic Sans MS">They're a black bake-o-light (sp) type plastic product, with the logo etched into the surface in white. Easy to install, but very brittle, so you have to be careful mounting your tires. Looks decent and the only way to dress up the rear calipers that I'm aware of. Depending on your rims, you might need the offset version to clear your wheel weights and mount the spare tire. I needed the offset version. They sit far off the caliper itself, so heat buildup shouldn't be an issue.
They have the Viper name in the wrong direction, at least if you compare it to a GEN III rear caliper, but again options are few and I think it looks better with than without.
I'll post a picture later today.</FONT f>
