Q: What is the track width, hub to hub of the GTS kit?
A: The GTS kit has an adjustable track width. The actual track width varies from model to model (A, B/E, C etc) as well as which brake kit. Generally speaking, on an A body, it is adjustable from 58 to 61 inches. The highest suspension travel, which is 6.5 inches, is at 58.5
