indicates curvature away from the calipers. The inner and outer barrels are the same for the same offset, but I prefer the look of the less-protrusive spokes. I contacted the guys at Evasive Motorsports and they gave me a form to fill out that they will send to SSR to have SSR determine what will clear or not. Convoluted process made more fun by Z1 not offering a dimensioned drawing for their 370Z Akebono brake kit, but they did have a template I was able to print in 1:1 scale and then take measurements from that to get the dims for SSR. I'll be sure to post an update once I hear back in case anyone else in the future decides to buy these wheels.
