How to put the power to the ground?
So I am no suspension expert so how do i get ALL the power to the ground?

right now iam spooled in the rear and have brand new tires with great tread and i can blow them off through 4th and if its wet 5th also when its wet its a bitch to take off quick because i just sit and spin drag racing Blows too because all i do is spin (W/O slicks) some say ladder bars but i heard that makes for BAD axle wrap? and ideas?

this is kinda a dangerous issue because when you NEED to GO you can't

Thanks
Brice

there is no axle rap with ladder bars they will limit movement but unless you use it offroad shouldnt be a problem.

These are "like" Caltracs. Calvert's involve mounting with a modified U-bolt setup, whereas mine bolt in under the shock mounts, but they work the same way:

It looks like somebody tried to edit the links in that thread, and the last few pics seem to be attempting to load inline. That is why I use direct links to my server - the images are huge, high-res photos that may or may not be compatible with web forums like this. So here they are again:

I do that type of fab work strictly on mock-up, angles and principle - no specs or measurements. The principle is the bars need to run pretty close to parallel the leafs in order to not bind. You want 90 degree angles or close to it on the fulcrum points for maximum leverage. Measurements to me means I take a rough measurement, cut, tack, mock up, grind, maybe cut again, re-cut, grind some more and re-tack until it looks right, then finish weld. Like I said in that original thread, I ended up taking them down and lengthening the bellcranks about 3" after they turned out to be too short on the first try. I'm a systems engineer, not a mechanical engineer.

Sorry, but I'm not mass producing this stuff.
