AVID RC has released a revised carbon fiber arm insert for the Hot Bodies D812. Sized down to .75mm (from 1.5mm), this insert not only looks trick but helps reduce suspension arm flex. This makes the D812 feel more responsive on the end you install the inserts.
Includes two front and two rear .75mm pocketed carbon fiber inserts (left and right sides).
AV1045-D812-SET Hot Bodies D812 Carbon Arm Inserts $30.00
AV1045-D812-F Hot Bodies D812 Carbon Arm Inserts $16.00
AV1045-D812-R Hot Bodies D812 Carbon Arm Inserts $16.00
