The all new Quattro sets the tone with a new speedy look by utilizing the KG 507/508 bodywork.  The Quattro chassis is lightweight and free which translates to faster times on the track. Like all Italkart chassis, high quality tubing is used throughout.  This frame is made of 28mm/30mm tubing and has special low drag brakes w/magnetic pistons to hold the brake pad off the brake rotor.  The instant you release the brake pedal the pad comes off the brake rotor reducing drag.   What makes Quattro different than the Laguna - Quattro?Quattro 17mm spindle w/8mm spindle bolt 28mm/30mm Chromolly Magnetic brake pistons to hold brake pad off rotor w/reservoir self adjusting brakes  Special 30mm axle Adjustable seat stays Caster and camber adjuster 2 bearing hangers 507/508 bodywork                                                    New Features 17mm front spindles 28mm/30mm Bearing hangers mounted to high grade chromoly. 30mm adapter for 30mm or 40mm axle 40mm axle upgrade is available.
