Your car can be both musclecar or HAMB friendly. For the HAMB just add skinny whites Cornell 1000 215/75-15 $45 ea. at PepBoys and lower it a few inches. For the musclecar look black rims with dog dish hub caps or baby moons no whitewalls, but redline tires maybe. Height for that look is good. Personally I would get supreme 5-spokes and skinny whites. But that's just me.
I like the chrome reverse just the way they are, maybe just lower it a tad or just try a different stagger on the tires, I think it looks pretty cool as is though.
I think a little lowering and some skinny whites on those chrome wheels would look great!! Here's Road Apple's (Coby) car for inspiration....
I think the chrome look good but the car needs a rake, or you need a set of redline or thin white walls. but I think a little rake would help.. (drop the front an inch or two). I believe when running chrome reverse the front tires need to be slightly smaller then the rears and the car should be on a rake (this is with blackwall tires)
I love the rocker trim, I'd leave it. Like I said before, the car looks great, just needs a little change in the stance.
