CNC-machined battery backstop for XRAY X12'19 made from premium-grade graphite material. The battery backstop and rear link brace allow for a wider range of battery placement adjustment.
The brace includes two holes into which the adjustable battery backstop is inserted. The battery backstop has 4 positions which allow the batteries to be moved more forward. The distance between each position is 2mm, so in total the battery can be moved up to 6mm more forward.
Frontward-placed battery makes the car easier to drive, reduces wheel lift in corners, and makes the car more predictable over bumps.
Rearward-placed battery makes the car more aggressive, increases cornering speed, but makes the car more difficult to drive. |
