Black paint finish is a but rough as there are smears. There's also black smears on the side of the rim which can't be seen once the tire is mounted, so not a big deal. Just a bit messy but good price. I wouldn't use these as a shelf car rim.4mm offset, looks great. Black paint can easily pealed off.Got these today,And must say they are nice rim`s.Hex size is 12mm.Off set looks 4-5,And will fit nice with my Hyper 10.Making it from 195mm with to 200mm without using wheel spacers.Only 1 thing i`m worried about is,The thickness of the 3 spoke In side the rim.Seem`s the spoke is about 3mm thick or so.So duno what`s going too happen at hi-speed.Will post results as they come :).I give it 4-crows for quality cos of the thickness of the spoke.Other than that there great.Nice looking.I will turn heads at the track. Overall 5 star`s! Price is good.Product is nicely packed too.
