Racers look here to help a newbie -Thanks
So, have YOU tried them? I have.....
I have them on my car though I admit I just installed them and have no direct experience with them yet. I researched it a lot before I went ahead and got them and I was convinced that they were going to benefit my combo. I am confident I have a decent grasp on why they work. Take that for whatever it's worth.
Before I made the change, my Duster had S/S springs and a snubber that were installed by one of the previous owners. It launched hard but not always straight and I felt like it may have been unloading the left rear tire at the hit.
Whoever was 'tuning' them before I got it 'adjusted prelaod' by adding an extra shock plate thing under the original one that had spacers and stacks of washers over the bottoms of the u bolts to separate them. I think it may have been to level it out some but I can't be totally sure. To me, this was a band aid fix for whatever they were experiencing. I figured there had to be a better way, so I got the Caltracs. I suppose we'll see how it goes sometime next year when I get the car back together.
The difference in weight was also pretty significant. Plus, it can be installed in a few hours.
Again, I believe they will be right for the O.P. intended goals. Obviously its his choice and I'm not here to argue about which system is better but IMO the Calvert setup is a pretty typical set up for this type of application (10 sec. car, 3,00lbs)
I would say for the time being to stay away from anything that reinvents the wheel (ladder bar) and go for the better mousetrap (Caltracs).
