B6 / B6D Carbon Fiber Steering Block Arms (Set) are made from 100% carbon fiber, offers Ackermann tuning options, and saves you a whopping 1g in weight! The set includes 3 pairs of arms: Kit geometry, +1 mid-increased Ackermann, and +2 max-increased Ackermann. This reduces scrub and allows the vehicle to rotate better in the middle of the corner. This rotation comes at the price of less steering at the exit of the corner. +1 is in between the kit geometry and our +2 to help you better tune your vehicle, it is suggested that you get our set of all 3.
