Thanks for the info/advice. BayouTiger, that's a VERY nice setup you got there - the 10s on the back really do add that extra touch, I'll probably try for those and see what happens. I was going to try for the Invos as well - we'll see how fast I run out of money there, though.
I was going to get some Boss 335s for the wheels - try as I might, I can't seem to find anyone online that has a pic posted of those on a Challenger (here or elsewhere). The one Challenger I actually ended up seeing them on was on a red R/T in the parking lot one evening about a week ago coming out of work. They had the chrome Boss 335s on a staggered setup (245/45/20 on the front, 275/40/20 on the rear); couldn't tell if they were 10s on the back, though. Either way, it sure looked nice. I think they had theirs lowered as well, but that's another project for another time. I have a black R/T, so I'll be going for the black 335s. I'll post pics when I get them.........
