Outer ring specs:
We worked closely with a race brake manufacturer that supplies many NASCAR racers and a couple major brake kit companies. Due to their expertise we chose to have them build us the outer rings to our specs to fit the B8 S4 and S5. The rings feature 12 attachment points for durability and strength.

Center hat specs:
We CNC machine the Aluminum center hats in house based on their recommended materials and thicknesses for durability. 12 attachment points for durability and strength. We also engrave JHM in them in 3 locations equal from each other, it looks clean and doesn't jump out or look tacky.

Thanks again everyone! Please don't hesitate to contact us if you have any questions!
