Weight Transfer and Suspensions

The adjustable snubber was never intended to be used with SS springs. It was a device to use if you didn't have SS springs. So automatic cars with SS springs don't need a snubber. A high powered stick car should have something just for safety reasons but it shouldn't actually touch anything unless something breaks.

The CalTrac setup with the split mono leafs and adjustable shocks is a good intermediate setup, or if you have to keep leaf springs because of class rules. They have a good bit of adjustment possibilities and in a lower power setup are probably better than ladder bars because they have more adjustment.

If you really want to get serious than a four link suspension is really the only logical choice but it would also entail the most money and modifications to your car. If you are making more than 600 HP though you are already pretty serious so it should be something you seriously consider. The CalTracs while good, definetely have their limitations and if you race at a track that might not be the best those limitations are going to be magnified 5x.
