Been using them for 5 years now with SS springs on my Dart Sport. Very consistant 60 foots, 1.40-1.42. Just using Monroe shocks on the rear, the bars in the lower hole. I set the preload on the bars with my weight in the car and have had no problems. Car weighs 3290 with me in it, and a small block pump gas motor, with 904 transmission and 4.88 gears.

if this works why does calvert tell you not to do it? they say to use a light duty spring. If you truely can do this its helps guys out like me that want to run the mono leafs but cant buy every thing at once. Can anyone else add to this please I have looked in the archives with very little sucess. Monte if you read this maybe you can shed some light on us. 1Qwkdart 
Thank you

I tried it and my car would do weird stuff like jump and unload the tires then it would go perfect next pass  Guy I got the bars from told me to get the monoleafs and then hooked hard and straight every time after that  Gus

I used them for a few years, then bought the monoleaf, to be truthfull there was an improvement over the car bouncing at launch, with ss springs, bounced every time, but did it the same every time and was consistent. With the mono,s car settld down, but the odd time, would get the bounce, but not as severe. I can only assume track conditions dictated a lot, car was still consistent, just the odd time ,and of course calvert tells ya not to use them, they are the seller taking your money, Tim

The reason Calvert wants you to buy his mono spring because with s/s springs and the bars there is not enough shock that can control all that and that is why you are getting your bounce. There is not a shock out there that can control that. With the mono the spring is just holding up the car and the bar is doing all the work. You would get way to much and too fast of body separation and not get the tire to plant and hold with s/s springs and cal tracs.

i ran SS springs and 3 way adjust shocks for 10 years--and they worked very well--------
then i spent the $$$ on the complete caltrac setup with the 9000 ranchos and WOW--i recommend this set up if you are running 10's or faster (in my opinion)
i've been running NOS for 15yrs and now N.A. and going 8.90s--doing 1.29 60ft and i love the adjustability i have at the tracks with this set up

Has anyone ever tried it?
I hear not to, but never got a reason why not.
Anyone tried it - YES
So, can you use Cal-Tracs with ss springs - YES
Is it optimal - NO
From my understanding on how the Cal-Trac bars work, part of the "leverage" the Cal-Tracs use to plant the rear tire is provided by the wrap-up of the front spring segment. The SS springs were designed with a stiff front segment to reduce spring wrap-up. Therefore they don't provide as much force on the Cal-Trac pivot bar, resulting in less downforce at the axle. Still more downforce than without the bars, but not as much as with a "softer" front spring segment.
Also with the Cal-Trac system, according to John Calvert, you want 5-inches of front suspension travel from resting static, to just before the wheel come off the ground. This movement is needed to get additional rotational weight to the back tires, again resulting in more downforce to the rear tires.
A lack of adequate front suspension travel can result in "unloading" of the tires a few feet off the line. Some of the unloading can be controlled with shock settings, but proper front suspension travel should cure most of an unloading issue.

trying not to hijack here (and failing?). could one remove some leaves from the ss springs and get more satisfactory results?
for what is the good life if not doing things thoughtfully?

as long as the springs are symetrical left to right they will work better.
biased rate side to side does not help with launch.
As stated earlier all the spring does is hold the car up.

any one run the split mono leaf? how much do the 2 halfs overlap? which leaf is on top..front or rear segment? on my 85 shortbed truck,I have the axle on top of the rear springs with a shackle flip and thought of makeing my own set of split mono leafs for the caltracs sytsem from 2 sets of main leafs from truck spring packs or would that be to hickabilly
