I'm running a car with monoleafs on the rear with a LR225 pound spring and RR 175 pound spring. I have a "biscuit bar" with a 90/10 shock of the top of the rear end. What adjustment do I make to the biscuit bar to promote forward bite when the track turns real dry and slick? Do I increase or decrease the angle?
Thanks

soften up ur rr spring to at least a 150 pounder or maybe a softer monoleaf, increase ur rear percentage to maybe 60 percent or more, increasing angle promotes more instant bite i believe.

raise it as far as you can!wouldn't hurt to take a little pre-load out also.(I used to run that setup!)

do you mean increase the angle of the bar or decrease the angle of the bar?

Take off the pullbar and damper shock. You'll free up the leaf springs. Add rear weight.

decrase the angle.When I used that setup I had 175 lb rr spring and a 200lb lr,on hoosiers.I think dirtmod10 is real close on the springs!Also are you running sliders on the rear of the mono's or shackle's?

Is that possible with monos? Does it work?

I assume dasher31 is running parabolic or composite monoleafs with those kind of rates. So, yes, it's not only possible, but I personally would prefer it. The rear of the leaf would slightly bind w/ a pullbar/shock combo above the rear. Anything you can do to free up the rear of the leaf helps wrap/unwrap, especially on dry slick.

the monleaf are normal steel monoleafs, 47 pound rate afco # afc20242, does this change anything? I can take the pullbar/shock off without risk of damaging anything?

OK, my bad. Did'nt realize you were running that lite of leaf w/eliminators. I don't know enuff about that set-up to offer any helpful advice. If you were running half-leaf or 2-link, then I would suggest putting more upward angle in the lower links, and more downward angle in the pullbar. But I would soften the rear coil springs on it to 175 LR & 150 RR.

I wouldnt take ur pull bar off that is ur traction device.
Have u thought about multi leaf Lr? we ran a afco 231 LR on our leaf car and afco 242 rr leaf with a 150 pound coil over behind and had great sucess with it. Also get a leaf floater for the rr, Randys race mart sells some good ones. www.randysracemart.com
