He is right about that, I had a pair that you could drive to the track, race, drive to dinner, and drive home on just fine. But as soon as you closed the garage door and hit the light switch it seemed they went flat.

Ok, but if I skip the tubes why would I need to drill out the VS hole with a 4 step? Stock VS should work without tubes right? In any event, I just want them to be safe, car is mostly street driven.
