cross

What percent of cross is to low and what percent is to high for a Rayburn

Good rule of thumb is 1 % of rear percentage, if you have 55 % rear your cross would be in the 54-56 %. This is with standard Rayburn setup.

I think Rayburn says cross should be within 2% of left side percentage.

I never use cross, bite only. I run even weight on fronts, sometimes favoring LF, then left % and Rear %.

we also tried to keep fronts even, and then around 54% left/cross, and 56ish rear.

Very nice. I actually learned to scale that way from two sources, one was Scott Bloomquist and the other was Frank McClendon from "Custom Chassis". Frank told me about keeping the fronts equal, but I learned along the way that sometimes when the car/kart is tight at center turn, off the throttle, that favoring the LF helps turn the corner. Ignoring, "Cross %" in favor of bite #, was Bloomquist. I even used this method in karts and always did well. Hope this helps and I like the 54/56 setup, kudos to "Dualj1".

How much bite do you usually end up with?

this is correct we had ours with in 5 pounds and the cars was quick on a dry slick track we had our best summer with this set up.

That will probably come up around 170 to 180

Depends on car and suspension type. With leaf cars and early 4 link it was lower, but modern swing arm and 4 link takes more depending on setup package and driver preference.

Just put 225-235 lbs in there and let her eat!

we were swingarm left, z right. We ran like 180 bite, and we'd go up to 220ish i believe. Was heavier but worked well for us.

F22 was a good setup, worked well in those cars. The pierce we have is way off in the front, 50-75 lbs split at least. Doesn't seem to make any difference though.

I have absolutely no knowledge on Pierce cars. I do know at one time he was based off a Rayburn but he tends to go his own way and I'm sure he's a good bit different these days, but I could be wrong. Down here in GA where I am nobody has a Pierce and Rayburns are almost non existant anymore, mostly Barry Wrights, Rockets, Mastersbilts and a few TNT and DWB's. Even GRT's are few and far between around here these days.

I read a article that said higher the cross the looser the car is. Is this true or false

more cross can loosen off throttle, but will generally tighten on-throttle. So more bite, and in turn more cross, generally means tighter.

Depends on where in the corner you are talking, more LR bite makes the car looser on Decel and tighter on Accel,
