The XRAY 301172 Aluminum Upper Deck Collar is crafted to reduce unwanted flex in the upper deck of the T4 2020 chassis. This reinforcement makes the car feel firmer and more predictable when running on high traction layouts, while the black finish remains low profile.
High grip tracks exaggerate chassis movement. By limiting that movement the collar helps deliver cleaner turn-in and steadier mid corner behaviour, aiding drivers who fine tune balance and corner speed.
Made to suit the XRAY T4 2020 mounting pattern, the collar installs without alterations. The straightforward fitment means less bench time and more laps to evaluate handling changes.
