The first function of any roll cage is to provide safety. Back in the day people were mostly doing roll cages just for the looks but with performance being the focus of current trends its best to pick up one that is actually going to save you incase of a track day incident. Cusco’s 6 Point cage is Japanese MOT certified and will pass D1 safety inspections. Its made from equally strong but lighter weight chromoly piping and is designed to be mounted in a way that should increase the chassis rigidity a bit.
Everyone’s safety regulations are different so you may want to check with your scantioning body before you pick this one up and put it on your track day car.
