Caltracs vs Slide A link Vs SS springs

You should really consider just using a MP adjustable pinion snubber with the SS springs and longer race shocks (25" extended height per MP chassis book) first. the hole set up cost about the same as Caltracs : $340

Yep, you get what you pay for - no doubt about that.

The caltrac site recommends using the special sliding mono leaf springs they make. The way the caltrac system works is the spring supports car in elevation while the caltrac bars resist the rotation force of the rear upon acceleration and basically turns it into down force forcing the rear wheels and tires into the ground.

Recommendations are just that - reccomendations. You didn't think they'd recommend using someone else's parts, did you?

The MOPAR SS spring, pinion snubber setup does the same thing: the springs resist axles rotation and the snubber reacts the force to focre the wheels into the ground!

Wow, a dynamically active snubber. That's a new one on me. Could you please explain this further? Don't understand how a snubber "reacts." Thought it was just a rubber bump stop preventing the pinion rising beyond a preset point under torque. Sounds interesting.

Basically, caltracs are for Fords and chevy's with leaf springs and MP SS springs and Pinion snubber is for MOPARS. Some MOPAR class and bracket racers feel they get a more consistant ET's using caltrac bars and springs, unless your car is leaving real hard and fast (1.5 second 60' times or better) I doubt you will much difference.

And also please explain exactly how is a Ford/Chevy leaf spring different from a Mopar leaf spring?

Inquiring minds want to know!
