Anyone have any ideas on LR bite when it gets dry slick? I keep thinking (and it seems to get me in trouble alot) but my ? is would you want to decrease LR bite when the track gets dry to increase forward bite and would this help side bite or am I just thinking wrong? THANKS.

Here maybe this will help, I'll tell you how LR bite affects the chassis.

More LR bite will tighten exit and loosen entry

Less LR bite will tighten entry and loosen exit.

So if you are looking to increase forward bite on dry slick, you can add LR bite but that will also loosen entry. So it actually decreases side bite. So if you like the entry and are just looking for a little more forward bite then you might want to look towards bar angles and such instead of LR bite.

Hope that helps!!

So if you would move the rr in to help side bite you will loose lr and gain rr. Would you add lr back and if so will moving rr in help anything. THANKS.

Moving the RR wheel in will help tighten the car all thru the corner. When you do it, put it on the scales and adjust the LR bite and cross weight back to where you had it. So yes, this would be a good adjustment to start with.

I have come to find that LR Bite will loosen a car off the throttle. ON throttle is not quite as much, the loose entry affect anyway.

Seems high L/R bite set-up or (high cross weight cars) are also the cars running lots of gear. Then they can give up some on their corner entry

I think it depends on the track. But yes high gear goes well with the lr high bite. I usually run lr high bite. But on a tacky track and enough rr angle in the car also. you can throw the car hard in and stand on it coming out.

ZERORACING, are you saying less lr on dry slick? I do run high lr 4bar on both sides when I say high left rear it is 115lb. split the car is real good when there is bite in heats but it has very little side bite and forward bite when it gets dry it is still fast but I need to find something that will help.I would like to run in the black where not very many cars can. THANKS for everyones help.

I run alot of rr angle in the bars on tacky so it drives loose off. So what I like to do for slick is stiffen LF spring to tighten entry. IF more exit drive is needed I go down on rr angle of bars(level out), and put more lr in, or adjust the indexing of the upper bar on my lr 4 link. The next step after all of that if the car is too free in and does the 4 wheel walk for the wall that alot of us feel I go to a softer rf spring. This will tighten the entry, and when you pick up the gas will give less of the lateral wieght transfer to the rf(meaning less crossweight will go down dynamically), so the rr will get a little more drive so that way the car drives netrual off the corner and easy to drive. Or a stiffer rr spring would do similar to the softer rf.

Have you ever tried different wheel offset on the rr to move the rr in or is this the wrong thing to do?
