too much LS%, not enough Nose%, and no where near enough cross, almost seems theres something wrong with that number, you sure the RF/LR show 39.5 cross?

Sounds like a stupid question, but were you sitting in the kart when you scaled it? Were your scales on a relatively level area? Do you have your tires at race pressure and stagger?

I'm guessing you measured cross with the LF/RR instead of the way most do it, which is RF/LR. I'm guessing you have dang near 71% cross.

Strange numbers!! The weights may be off, but the % are right.

Here is my numbers again... Left 60.4 Front 45.3 Cross 41.1 total weight 392

Tire Pressures--- LF 15 RF 5 LR 6 RR 8.5

Stagger------- LF 37.5 RF 37 LR 37 1/4 RR 39 1/4

i run on a very small bull ring track with tight turns, some banking and bite in the track
 
im no professional but Lf needs to be smaller than rf, and 2" of stagger in rear maybe to much but the smart guys will chime in!
Tire pressures seem crazy to me also, but very curious what everyone else has to say

First things first. Tire pressure should be Left tires 5psi, right tires 6, or 6.5psi. Remember this is just for consistent scaling.

Stagger: you're ok on the back, 2" is manageable. You need to have your right front at least an inch bigger than the left front.

My thoughts on baseline numbers, I'm not an expert but just a guess at the ballpark. Your left should be more like 57-58. Nose weight should be 46, and cross should be around 60-63%.

I'm still baffled at 41% cross as it stands.

No staggr in the front will drastically change the cross .
Front stagger needs addressed as does air pressure .
The driver is in the kart??

You've got to be kidding!! 5% rear bite, when the rest of the world is running 100 to 200%. I'm skeptical!

Set your pressures to either 5 and 6, or 6 and 7 and measure your staggers again.

53% cross is getting warmer.
