This Factory Pro O-XCP004 Body Rideheight Downstop Set is an accessory made to work with the XRAY T4'21 touring car chassis. The downstop pieces create a reliable lower limit for body rideheight so body clearance stays consistent during setup sessions and track running.
The components serve as fixed mounting points between the polycarbonate body and the chassis to define the minimum allowed rideheight without altering suspension geometry. That consistent body-to-chassis gap helps when trimming bodies and when checking aerodynamic settings between laps, because the gap is repeatable.
Installation is simple for experienced builders: the parts mount at the standard body post positions on the T4'21 and are adjusted to the chosen stop height rather than acting as suspension travel limits. Hardware contents are not guaranteed here, so confirm the vendor listing for packing details.
Tuning use: fit this downstop set as a baseline when testing body cut lines, wing positions, or when copying setups between matching T4'21 cars to isolate rideheight-related behaviour during setup changes.
