I’m totally not into show cars but the polished and black lines are fine, the car needs to be one color when ever you figure that out. red and purple don’t really go together but if thats what your gonna do, then anything of color should be painted or coated to match. like if your gonna keep the cam gears exposed they should be black or purple not gold. throttle body linkage.
if the cam gears won’t be exposed then you just wasted money on arps. i like the arp idea its just expensive and now that you’ve started with that theme you have to continue. red, purple and arp theme. thats pretty odd but if you stick to it thou, will be cool.
