Race Stud Kit

This is the strongest way to stud your engine. You must be able to use a 13B Cosmo front plate with the 7 bosses on the outside. 

This allows us to machine completely through the plate enabling the fitment of nuts at either end of the custom stud. 

As these bosses are mainly concentrated on the power side of the engine there is now reduced stress and load on the front plate due to the studs keeping the engine under compression not tension, greatly reducing the risk of cracking.

This modification can also be applied to 20B engines using a 13B Cosmo front plate.

Used plates may also need to be surface ground. See "Surface grinding" section for more information.
