Leaf spring traction bars
Moderator: Team
If changing the length is not workable you can simply increase the gap but that will cause more spring distortion and more shock with a clutch or trans brake. Adding a leaf or increasing spring rate will reduce lift. You want the lift, just not way more than needed. If you suddenly hit a travel limit the rear tires will unload momentarily.
You want just enough lift in the back to plant the tires, and no more, just as you want enough front end travel to get the weight transferred and up on the tire, and no more. As far as traction devices, yes guys have gone fast with slapper type bars. You work hard enough at something, eventually you will get it right. If it isn't broke , don't fix it. However just because a car hooks doesn't mean it is working. The Cal Trac bars were a good idea, however I like the new bar that is out, very similar in design, not like a Slide a Link, but the Cal Trac. The difference being is they have 3 adjustments front and back for better control of instant center, or your lift point. Hope this helps.

shocks
automotive breath I thought you forgot me. These pics are awesome. I assume your guy runs a trans-brake, as I don't. I do have hope for single digits though, my mph is 129 in bad air. Also, I changed a few things. I took some pre-load out in back, [ should hit the tires harder]. Next, I let the chain out of the front [ had it restrained]. Now have about 3in more rise. Looks more like your pictures. I hope it helps. Thank You. Dan.

I cannot stress enough how important rear sway bars are!
I was no longer driving the car consciously. I was driving it by a kind of instinct, only I was in a different dimension.
