The 4-step custom SOP
- Step 1 — Send your spec: car model + brake spec, or a reference photo. 1 set (4 pcs) is a real order.
- Step 2 — 24 h engineering: 3D CAD drawing with big-brake clearance verification and FEA load analysis. You sign the drawing before we cut.
- Step 3 — CNC + finish: machining, then brushed / polished / anodized / two-tone finishes and custom center-cap logo engraving.
- Step 4 — QC & delivery: runout/balance/finish QC, photo report, then global air or sea express door-to-door (DHL/FedEx for sets).
