Fits both 335i and M3. Hanbin Designs makes a function rear seat delete to cover up the empty hole left behind. You don't need a roll cage for this; also not included.
Made of quality watercut jet plastic, fabric, and hard work, this is the right thing for you!
It has a pair of hinges to allow folding down the back.
NOTE: IF YOU HAVE A ROLL CAGE, YOU CANNOT FOLD DOWN.
Install is not difficult to do by yourself.
