since you have the 5axis idk what kind of clearances you have for moar low. i know i couldnt do a lip without killing it now lol, and ive removed about everything to get as low as i can on my c8sports.
hope the 18's let you at least run flush. as for painting the centers black im on the fence too. i mean my rs' center caps are black so i know itll look good. i think keeping it all polished will make it cleaner though. the window black was a good call.
Yeah they actually arent fully polsihed though. I am just tricking your eyes because the centercaps are plastic and they are currently painted silver.
Yeah, the good thing about a urethane lip is I can scrape without breaking it
