Bezerk RC option part for the AE B64 4wd buggy. This is a pair of 0/6 degree (AE142) and a pair of True Ackermann steering arms.This will provide you every step you'll ever need in two steering plates. Every 1mm you add to the rack subtracts 1 degree, so now you have from -2 deg to 9 degrees of Ackermann adjustment with the two types! Made from glossy 2.5mm carbon fiber. Like all Bezerk products it can be customised to suit your needs. 0/6 (AE142) pictured on left and 3/9 (AE139) pictured to the right.
