TQ Racing is now TQ wire. TQ Racing reinvented slot car lead wire when the Superflex wire is introduced in 1990. With 413 strands and bare copper construction, it was flexible and resisted the “wicking” action and breaks caused by tinned wire. This was the first wire that was really designed specifically for slotcar racing. Leadwire was a first product, engineered to provide the slotcar racer with the best wire available.
