If you can weld I would do the technotoy style ones. It is much easier for quick adjustment, espcially at autoX between runs. You can change the camber on the weld in style on all 4 corners in less time than you can do one of the msa style ones. May not sound like a big deal but if you drive to the track/corse, have to put your camber in, run the car and then put your street camber back in, you'll see the benifit.
