i have a 2001 slk 230 i would like some black rim/wheels for i. but i am clueless about off sets and other things i just want 4 black wheels. is it bad to do non staggered wheels? basiclly just explain to me like i am a 4 year old what i need to look for. a really slow 4 year old lol. i want to stay as close to factory as possible if i can but as long as its not bad for the car i can change some.
