The XRAY 301198 T4 Graphite Upper Deck 2.0mm - V3 is designed for drivers seeking cleaner steering and improved traction on a T4 2017 chassis. Built from quality 2.0mm graphite, it maintains low mass while adding structural stability where it counts.
This upper deck uses a specific rear contour to increase traction and stabilise steering inputs. The change in geometry helps deliver more predictable mid-corner behaviour and smoother exits.
The revised layout makes pinion access easier, reducing service time between practice runs. For additional tuning, the deck accepts the optional belt tensioner (#303071) to help control belt slack and consistency.
