Track is 1/5 mile clay oval...Almost no banking.
Kart weighs 240 now and need it at 250.
Front 46%
Left 52%
Cross 57%

Where should I add the 10 lbs....? and how far off are these numbers...? Maybe more like 54% left and 55% cross....?

Start here....
54.5 to 55 left side
52.5 to 53.5 cross
try to get the nose weight in the 44.5 range

Did someone give you these setup numbers , or is this just how the kart weighed out?
The only way a high cross setup will be fast normally) is when you have control over the caster split...the 99 umax does not. The setup I gave should put you in a neutral range and you can look for improvements after you get an established baseline....btw put the 10 lbs where ever you need it. Just keep it low. Might need 5 on the back of the seat and 5 on the left fram rail....just guessing though...
