Stock 5-Speed Getrag trans yes. I'm using a M3 flywheel, clutch and full M3 clutch engagement system (Master Cyl, piping, slave Cyl). No issues using the stock trans, but the stock 318ti flywheel, clutch & pressure plate aren't strong enough. (Ask me how I know.... ) Your not thinking about using the slushbox are you?
