You will need a thin wall 3/8 6 point socket, philips screw driver, 1/4 torque wrench and a paint marker to install this properly. Fidanza recommends that you torque the nuts to 5 lb ft of torque. First tighten the nuts so that they are hand tight, and ask a buddy to help you hold the flywheel up or use a vise with vise jaws. You want to torque the nuts, and not the philips screws. I also recommend cleaning the flywheel thoroughly. I took an extra step and used 600 grit sand paper to get the surface underneath the flywheel disc extra clean.
Great product! Easy figment, all holes lined up perfect, had to drill the heads off of all the bolts due to socket figment issues but they send replacement nuts and bolts, will buy again!
