u cant hack away at LFS textures u can edit or mod wat is already there but,
Like on the RB4 my intercooler and boonnet scoop grill is changed it looks more like grill and the intercoller has my drift team logo on it also i have seen BLITZ and other logos on them as well. Just edit the dds. file textures in ur DATA\DDS file its very easy even a n00b kinda person at PS could do it.
you .. also pulled up a question that makes.. no sense lol
(also.. none of the demo cars have intercoolers so..um.. ya.. unless you want a skin with some giant intercooler pictures, im sure that can be arranged)
