If you don't want to drill any holes, buy the Brey-Krause seat belt mounts for both sides of the seat. They mount to your factory seat belt points and allow the competition lap belts to snap in and out. Also go with the 6 vs. 5 point system. The sub belts mount underneath you seat rail mounting points.
Torsion bars, bushings and camber truss are my winter projects.
