We’ve seen this F1ULTRA R5 lower diffuser at the track, but now Exotek has made it a reality. 3D printed from nylon, this lightweight diffuser (only 10g) is a direct fit for your F1ULTRA R5 Formula 1 car. It includes mounting screws and, as an added bonus, also protects your spur gear in the event of a crash!

It is also said to provide extra downforce and rear grip!
