i just got my car scaled and the ex'latemodel racer that scaled it claims that cross weight is not important he claims that the split between the 2 front tires and between the 2 rear tires is all that matters. now i realize that if you set those weights that a wedge number will be constant. however he came up with the wedge being like 47% and i know in the past i was at like 52% but always had entry push im just concerned with spinning out and collecting the field on the first lap. i race a ump modified on dirt. thanks in advance. jl

What brand of car do you have? Alot of chassis builders have a base line setup and pending on Who built your chassis depends on what numbers are important. I look at all the percentages, as reference to look back on and to improve upon and learn!

47% is too low. Also 52% is a little high for a baseline setup. If you work the jacks some you can usually get the wheel weight splits, keep your ride height that you're looking for and achieve a good neutral setup. Start out with something like 50.5 to 51 for starters. Most guys will run 50 - 52% as there range, if you're tempted out of that range there is usually something else that needs to be changed.
