What general trailing arm lengths and angles seem to work well for you on a locked setup with the shock located behind on the left rear? How much wedge is actually added to the car under acceleration? When this happens, do you try to get more rear steer to get the car around?

I do not know if I'm unserstanding you right. But if you know people locking there birdcage to the axle with the spring behind, please get them to STOP!! They are going to break something and then who knows where there going to go. The Spring located behind the axle on the LR should always be floated, and if you know how to get a true dynamic wedge reading please pass that along *grin*
Bar lengths Hmmmm...Every builder is in this range 16 to 17.5 (top)...14 to 15.5 (bottoms)
Hope this helps

Clamping the B/C to the awle tube with the spring in front, is a old but still very usefull practice. Under accelartion the B/C will warp up with the axle thus adding wedge to that tire. It does the same thing with the spring behind on the LR but floated thus allowing the car to de-accelarate much less violentlty. I hope I explained that muddy water clear enough. *grin*

I was thinking that was what he was talking about....Clamped Locked either way she is gonna go with the axle under power and off the gas...Lots of go straighters around here weld there b/c up on the tube...I've talked a few guys into trying rayburns deal, and those guys are having to rethink all there clutch packages...lol...When there not busting heims and hitting the card rails...
