Aluminum QC brackets

[Kevin05]

Any tricks on keeping brackets in place on aluminum tubes?? I'm use to my old 9" Ford and just putting a good tac on things to hold them in place. Are the retainer rings enough?

For the caliper clamps we drill holes all the way through the tube and run a bolt down in it. For everything else we just dimple a place in the tube (using a drill) and tighten the bolt down. We've never had one move on us before. The panhard bar bracket receives the brunt of the lateral force of the car during cornering so you could probable get by without even dimpling the tubes.
