Could not pass up the deal for the BBK for under $250 and just got in today. Overall for the price you cannot beat this deal. I still need to get rotors and pads so most likely going to order the z1 kit with SS brake lines too. Wont make the swap till the warmer weather. Just a caution idk if anyone else had this happen but some parts have white on the over the powder coat not too big of a worry for me since I am going to get the re powder coated blue. Here are some pics
Yeah, that looks like paint marks for marking the bolts to me as well. Otherwise those look really nice for the price!
FYI.. If they are truly powder coated then their need to burn the red off in an oven... bead blasting or sand blasting really only works well for painted surfaces.
AS far as the paint on the bolts goes, the aircraft and I'm guessing heavy machinery industries use something called 'glyptal' as a movement indicator. In non-heat-sensitive applications I've used nail polish.
