I would also like to see more classic NFS body kits/parts as well as name-brand parts from Chargespeed, JUN, etc. It would be nice to have at least a few of these body kits available to put on our own cars.
body kits are only available on the uncustomizable K.S. First of all, some body kits are locked away in the game files and are only used on certain cars like the body kit on Ana's 350Z, Rachel's 350Z, and Eddie's Skyline.
NFS Heat's Customization is good, but some things are lacking.
