TRF421X Carb. Versteifung hinten 2mm

The TRF421X Carb. Rear Stiffener 2mm is a dedicated model part for the TRF421X platform, built to add a 2 mm carbon brace at the rear of the chassis. Its focused role makes it useful for builders who tune a car through specific structural changes rather than broad part swaps, with the rear section addressed directly by a single component. Carbon gives this stiffener a rigid, lightweight construction suited to competition-oriented setup work. As a rear stiffener, it is intended for one defined mounting area, which helps keep tuning changes controlled and easier to track during rebuilds and test sessions. The 2 mm thickness is a concrete specification for matching the part to the required setup and compatible chassis layout. Used as a replacement or upgrade part, it supports maintenance as well as planned setup variation within the TRF421X range. On the bench, this kind of part fits naturally into detailed chassis preparation before practice or race use. It suits builders who compare setup changes step by step, whether refreshing a worn rear brace or preparing a car with a firmer rear chassis configuration for the next run.
