The Caltracs are just a fancy "slapper bar" system. Caltracs are a few hour job with NO welding and leaving the rear end in place.

The triangulated systems are NOT afternoon bolt-in jobs. The short upper bars on the triangulated systems and the amount of adjustment on both upper and lower bars limit their HP level.

My guess is the HP limitations of both are about the same. The next level would be back-halfing the car.
