Test mounted!
Perfect radial offset. The shop mixed up translating a dimension, so I'm getting another set of brackets. made.
There's over a CM gap with my Titan TS5 wheels in 18'" diameter, so room to upgrade to 380 or even 390mm rotors in the future if absolutely necessary (shouldn't be, I have a friend running these with his Camaro SS in 372mm and C6 Z06 in 355mm without temp issues).
Anyone interested in getting this kit, post to let me know! I can get these made in 6061 or 7075 aluminum.
