usra bmod set up

[powerslide]

I did a did the shock on the arm when i had a bmod. Your milage may vary. I also only ran about a 200, the motion ratio says thats really soft. But with all the stacks on LR 4bar stuff trying to make it soft as possible i'm not sure i was that far out to lunch

One of the worst mistakes I ever made was to make too many changes at one time. If you increased you LR bar angle, I would try that and see what it does before changing anything else. One change at a time so you can see how the car reacts.

Ya I just did that Saturday night. won Friday at one track and Saturday night went to another where it was their championship night. no heat races, just a main. needless to say I over thought it and threw all sorts of adjustments at it. no I know what not to try when I go back for their open show next weekend!

if running the soft lr preloaded do we need to go up on the rr? currently running a 150 lr and a 125 rr. Thinking about trying a 125 LR and a 175 RR. We have been playing around with the pullbar long and flat (10*) and has been working well. Anybody try chaining the RR down? Heard this will give tons of bite but is easy to mess up and go to far.
