Anyone switch from super stock springs to the Caltracks split mono leaf find their car reacts quicker?

Geez you know I'm not sure?? I went to cal tracs first then dropped the SS springs to the cal tracs and monos. I was focused on traction or holding traction so never noticed.
But if front and rear of spring are stiffened and at the hit springs have to wind up and arch and the cal track system mostly stops that it would make sense that energy moves you forward faster/sooner but we may be splitting hairs hear as in a couple three 100's???

I thought my car reacted slower with the caltrac's. I have them set in the bottom hole, haven't tried the top hole.

My reaction times have slowed since I put on caltracs (was on regular stock springs)...but then again, my 60' times have slowed too. I'm about 4 hundredths slower in the 60' in similar air (1.54 on caltracs, 1.50 stock springs). I've been tuning the caltracs for over a month now...still can't get the car to 60' like it did before.

I don't have Cal_Tracs yet, but considering them.
But just wondering....wouldn't preloading the Cal-Trac adjustment more produce quicker vehicle reactions because there would be less movement in the suspension?

I haven't used Cal Tracs but if the car 60 ft. quicker I would think the reaction time should be quicker I like and use ladder bars when switchig from leaf springs 1.37 60 ft. so far My reaction times are all over the place from -.001 to .637 on the same day, it's h--- to get old At least I'm still driving, having some fun and complaining about my lost skills

Keep at it Cab

I don't know about reaction time changes, but Caltraks made my car more consistent and let me change ride height.

I had to change where I was leaving on the tree after putting cal tracs on the duster. I was leaving on the second yellow, but now moved to the 3rd. I also went to a taller front tire hope to slow it back down, but didnt help as much as I'd hoped for.

I picked up very little.. But I can say that I like driving the car a hole lot more now than with the SS springs. That car was all over with ET, and felt like when I was in 2nd gear that I was on a fence post. The car ran anywhere from 9.85 to 9.98 with SS springs, and a best with the cal tracs of 9.80. Did they help, I think so.. I felt it was money well spent.

LOL!!
Me too but I've won more races the past 5 years with less red lights!
I've won one race averaging .100 reactions.
Hope my new ladder bars and cam bring me around two test days last year with the ladders before I hurt the motor seem to get my reactions .015 to .035 area??
Hope to be back in the next week or two!

Me too! Absolutely no gain. Went to ladder bars, and the difference was like night and day.

By the look of this photo my car likes to rise up a long way before it decides to go forward. I foot brake on a .500 tree and usually cut .600-.620 lights when I just tickle on the stage bulb. So I have to bump in a little deeper but then I'm anywhere from .480 red to .560

Now I have to decide whether to upgrade to Caltracks, ladder bar, 4 link, or tranny brake.

Looks like you need more air... BUT if you think what
the Caltrac does(its making a truss) on the back suspension
it should help apply the torque.... also you do have
alot of rise to the body so stiffer shocks would help
IF the track is good and hold... most everyone that
I have dealt with say its a much more consistent
package but they also tend to say good enough.. thats
why they dont know if its quicker in the 60'... they
just accept what they have.... it still takes work
to get it dialed in.... and in MOST cases it takes
a better shock to do it but most dont spend the money
to do it... and almost all of them run the Rancho
9000 shocks and most are set at 8 or 9 so they dont
have anything left to adjust
