leafspring car handling

As in 9-3 which valving bilstein or other?

[Dirtrunner35]

Yes. Just like the motion examples on the scales that Canuck was using on that link. Now magnify the examples by the force of a 2500# car rolling into the corner. There is a compounding effect with more momentum. He uses the word momentary for the time of change because he is waiting on all 4 corners to relax on the scales.Correct for the example, but on track that change lasts as long as the force of the RF spring stops compressing.

Trying the best I can to answer.

In his example the more rebound on a corner reduces the cross weight

Shock is a 9 length and a straight 3 valving. Bilstein it would be a 30-30. I have found over the years that a twin tube shock works better on leaf springs. Gas pressure does not let them move as freely. Others may have a different experience.

What would the car act like on dryslick if I was to try a 20/60 on lr and a 40/10 on rr would that tighten the car up coming out if the corner? These are bilstein numbers

Witch one would give more lr bite on exit a 93 or a 95 shock on the lr of a leaf spring car??? Thanks

The 3 in front of lr on tacky and 5 and above behind on dry.

[frontrunner]

So a 95 shock on lr for slick behind so would the rr shock stay in the same place and who all agrees with this????Thanks

What you have to remember is leafs also act as a mechanical traction device. By floating the rr you also cut the rate in half of pinion wrap. you also are using the shock for and aft to control the wrap of the pinion and how fast the traction is applied. Make sure if you float rr or move leaf packs for and aft that you also change your shock mount so you do not bend any eyes of the shocks. Also leaf cars we go all the way to 4" stagger tacky to sometimes reverse stagger as well. I personally don't like reverse stagger because there are other ways to control other things that the reverse stagger is crutching. Also to add the normal 7-2 8-2 high compression shocks on a 3 link or 4 bar do not apply to leaf. Youll want the compression but also the rebound higher as well. You can tune the mid turn throttle push you always see by increasing rebound.

take your lr shock off on slick smooth tracks

Explanation....

[dirtrace09]

I have never taken mine off but have ran a dummy shock there on the slick. Leaf cars need to let the left rear leaf move as freely as possible on the slick. That is why I suggested a straight 3 valving earlier on the left rear. It has always worked for me. Others may have different opinions.

[stock car driver]

wouldn't a dummy be the same as taking it off?

[dereksehi]

What do you run on the rr for a shock ?

[stock car driver]

3030 or 4040

[dirtrace09]

Yes it is the same. I wasn't disagreeing. I was just commenting that I have never tried to take it all the way off. I was validating to racementally the reason to remove it or run without any pressure or valving.
