AVID have introduced a HD front suspension mount for the XRAY T4 line of cars. The mount is machined from 7075-T6 aluminum and comes orange anodized with the Avid logo laser etched. The mount for the front-rear is a solid piece that bolts into all 4 screw holes making the front end very stiff. AVID found that this helped increase the immediate responsiveness of the steering and can be used in a plethora of track conditions. It all just depends on your setup and track conditions, so AVID recommend trying it once you feel comfortable with your car.
