4 Second Racing Club
4SRC GTR35 GR6 Gear Box Upper and Lower Transmission Brace Kit
The 4SRC CNC GR6 transmission brace kit includes both upper and lower mounts that reinforce the connection between the transmission and rear differential housings. This effectively protects the housings from damage during hard launches, as the connection point is typically the weakest area. If you are upgrading your transmission or planning to do so, this kit is a worthwhile addition.
