swing arm lr, spring on housing, z link rr.
we had a 1/4 lead on rr.
we could not keep the corner speed that the 4 bar cars had, I tried something . here is where we need opinions. I trailed the rr by 1/4 of an inch trying to get some rear steer with out changing bar angles. we went out and won the heat by a staight away,BUT a couple of times coming of the turn the tail kicked out just a little and the driver had to back outjust slightly. I did not change any percentages, just leed, heat race so bite was very good and corner speed was better than ever, a couple of laps he did nto back out at all!! we got rained out after the heats so we don't have a full feature this way, thats why I need opinons!!

do I bring the rear back forward on the right{even up}, leave it trailed and put more lr bite in[ 160 # , 1" stagger now], or do nothing and see how bad it gets loose during a full feature. Thank you

JMO, but it doesn't sound like you're too far off. I'd probably take a stab at putting a little more wedge in it if you anticapate the feature being slicker. I'd try that since it sounds like you want the rear steer for the corner.

i agree with dirtzone, but if it gets really slick that rr trailed even 1/4" might take side bite away. i have seen this happen to some guys, not saying it will for you, but if it does i would then get the rear steer from the suspension(change the bar angles) so that you get the rear steer when you need it and then the rearend squares up coming out of corner giving you max forward bite. JMO, might not work for you but hope it helps

Did you recheck your percentages after moving the rr as moving the wheel fore/aft will affect the percentages. I would add a little bite to the car to compensate for the rr trail and go from there.
