The XRAY 301172 Aluminum Upper Deck Collar strengthens the upper deck to limit flex on T4 2020 chassis. It is intended to deliver a firmer platform for setup work while complementing the car's factory styling with a black finish.
Sticky surfaces demand consistent chassis behaviour. By reducing upper deck movement, the collar helps the car hold its line through corners and improves steering consistency when throttle is applied mid corner.
Specifically tailored to the XRAY T4 2020, this collar fits in place without cutting or drilling. The installation process is straightforward so you can get back to track testing quickly.
