Enhanced grip and 500 grams of mass define the Contour's smooth and precise shifting experience. The grip ring is an intentional ergonomic undercut below the sphere that provides an ideal location for your fingers to sit, grip and shift. The finishing touch is a glass beaded finish to create a satin appearance that accentuates any interior. The Contour comes with an adapter that will seamlessly mount it on your car's shifter arm with OEM fit and finish. Customize the Contour with our signature cnc machined shift gate engraving. Please allow 3-5 days for engraving. CONTOUR BEADED Part of our Mass Series collection, the Contour is weighted for performance shifting. The utilization of stainless steel creates a shift knob with mass to smooth out notchy shifting.
