These are the numbers after I scaled them the clone sumo was actually the 450 sumo not 435 different tracks

The other one is from the predator 400

How far off do they look

I've seen a lot of setup sheets over the last 10 years, which doesn't make me an expert in any way shape or form, but your numbers look very close to most of the numbers I've seen. There is one thing; recently I've been seeing much higher rear cross numbers being used. Of course the more weight you put on that LR the closer your stagger has to match the track your racing on.

These numbers match my spreadsheet exactly. I have one advantage; I can change just the total weight and all the corner weights will change. This lets you know what you have to change to make the setups exactly the same. Of course they won't react exactly the same on the track because of the extra weight. Role centers change, tire loadings change along with tire needed pressures. I think.

The fact that this iPhone app is free is an advantage. I charge money for mine.
