The 3Racing Tamiya TT-01 / TT-01 TYPE E Graphite Upper Bumper, model number TT01-11/WO, is specified as a direct-replacement upper bumper that reduces flex at the front end while keeping mass low. It is intended for racers who tune chassis response as part of setup work.
Graphite construction raises local stiffness at the nose, which can sharpen turn-in and improve recovery after light contacts. The change is subtle but consistent for drivers adjusting front-end behavior during setup sessions.
Install using the factory mounting points on TT-01 and TT-01 TYPE E; no chassis modification is required. Check screw torque after first few runs and verify that body mounts clear the new profile when using low ride heights.
