The XRAY X1'20 Graphite Top Deck 2.5mm is a targeted upgrade to control chassis longitudinal flex and adapt handling to varying surface grip. It provides a simple path to more consistent steering behaviour.
Tightening the top deck nut removes longitudinal flex, which improves steering response and precision on high-grip circuits or with soft tyres. This setting helps maintain predictable turn-in under acceleration.
Allowing some flex by loosening the nut delivers improved mid-corner stability on medium-grip tracks. For lower grip, taking the deck off increases mid-corner steering and can aid corner entry and rotation.
The top deck is supplied with a hole to accept a shock adaptor, making it straightforward to set up long-shock layouts without altering the main chassis structure.
