Back when I started racing I seen a chevy car blow a pressure plate , it came up through the floor boards then continued up and out in front of the wind shield. Basically totaling the car. Also while all that was happening the floor board metal was rapped around the drivers foot breaking it and secured him in the car. That made a pretty good impression on me at the time and ordered a lakewood as soon as I got home. Back then I still ran a stock flywheel and clutch assembly but felt secure knowing that everything would be retained in the Lakewood if something did let go. Dialing in the bell housing is just something you have to do on any aftermarket piece. If your just going to street drive just use what you have , if your going to do any high RPM shifting , do yourself and others a favor, buy a blow proof bell housing.
