Pop the hood. Give them a reason to look.

Big upgrades get the attention. The details make the build. Give your BMW G29 Z4 M40i the titanium hardware it deserves, with a coordinated finish that carries your vision right down to the fasteners.

Real titanium. Serious presence.

Grade 5 Ti-6Al-4V titanium bolts, nuts and washers bring the kit together. Hot forging and precision machining shape the hardware; the finish gives every mounting point its own character.

Choose PVD Aurora for shifting color or Fire Burnt Blue for a heat-gradient finish. See the installation gallery for the hardware supplied at each location.
