Avid T4 front suspension mount
The HD Xray T4 Front Suspension mount from Avid for the front-rear is a solid piece that bolts into all 4 screw holes making the front end very stiff. Testing found that this helped increase the immediate responsiveness of the steering and can be used in a variety of track conditions. Made from orange anodised 7075-T6 aluminium it features a laser etched Avid logo.
