Destroy or DieFront Super Knuckles SpecificationsMade in England these Super Knuckle front hub carriers from Destroy or Die have been specially designed for Mazda MX-5 or Miata NA and NB. Developed for drifting they offer a 40 mm roll center correction and eliminate bump steer (variation in front wheel alignment during suspension travel) for excellent steering response and superior control.These parts allow a large increase in the steering angle up to 65 degrees if they are associated with steering lock adapters and drastically limit the Ackerman effect for spectacular drifts at very high speed and with maximum steering angle. It is even possible to pull off backward entries (front of vehicle pointing backwards when entering corners) !The Super Knuckles can be mounted alone on a stock MX-5 but will be vastly improved with the adjustable lower arms allowing the wheels to turn with maximum amplitude. For installation the manufacturer recommends using OEM or Powerflex polybushes.This set includes 2 front hub carriers (left and right).
