You can use plasti-dip on the wheels and if you dont like the pink, you can peel it off and change it.
Swaybars link the left and right side suspension. If you go around a corner, the left side will dip, and the right side will raise up. The swaybar helps to counter that by twisting (specifically, resisting the twist). Bigger swaybars provide a bigger resistance to that twist and help the car stay flatter.
I did actually try the blaze pink plasti-dip on the lettering on the back of the car before I debadged it. It faded really quickly and turned more orange over a few months.
I didn't realize these cars could get any "flatter" to the ground! Holy.
