Running an aluminum seat in your Exocet? Add a Competition Engineering seat back brace to tie the seat into the Exocet’s roll cage structure. By tying your seat into the sturdy roll cage, it will stay in place under heavy acceleration, braking, cornering, and damaging situations. These braces use a 3 in. by 6 in. backing plate for attachment to the back of non FIA-approved seats and can also be used on approved seats for added support. The braces feature a locking collar to allow the seat to move back and forth and no welding is required for installation.
