G-Star (G. ): High performance sintered metallic compound for extreme conditions. G-Plus (G+): High density organic ceramic compound for all-around performance. Due to higher friction/heat properties, the G-Star compound should only be used on systems originally designed/fitted with sintered pads, OR in conjunction with heat-dissipating braided stainless steel tubing. Goodridge braided brake tubing combined with G-Plus/G-Star pads will offer the best possible performance and control.
