In our opinion this is the cleanest solution to mounting paddles to your steering system. This sandwich plate goes between the steering wheel and hub. Slots in the back allow you to run wires into the steering column clock spring out of sight. Step on plate face gives clearance for leather on the steering wheel. After clicking one of these paddle shifters you automatically feel like a racing driver. These paddles have an unmistakable snap. Magnets are used to make the shifters feel crisp, just like in factory race cars. Paddles made from true 4mm carbon fiber with a "+" and "-" sign cut in them for upshift and downshift. Long pigtails to route wires however you like. The mounting plate is CNC cut from billet 6061 aluminum and anodized black at our location here in the USA. Bolt pattern is standard 6x70mm, common to OMP, MOMO, SPARCO, etc Includes: Made in the USA Carbon Fiber Paddles with "+" and "-" 6x70mm Bolt Pattern Anodized in Black
