I have a spreadsheet to figure a starting rear stagger, but I need to know the radius of the turns. Just taking a guess-ta-mate, figuring a 77.5’ radius turn, I’d say the stagger should be near 1 3/16” Most likely less with the banking.
Seems to me you could run more air in the RR tire. That banking puts a lot of pressure on that RR tire.

What problem are you having? If it were me, I start on this for a track with good bite on a badmax:

46.5 n
56 l
62 x
.5 lf
-2.75
1 3/8 front
1 3/8 rear
Tires at 52 duro wiped with a bite chemical

If your running tires that soft I don't think the track is producing the bite. It's more prolly a chemical bite from other racers prepped down tires.... I'd go with
Cross 60
Left 57
Nose 46
+.5 Lf -2.25 rf
Stock castor
1 3/8 front 1 1/8 rear

Yep, more cross and a little more rf camber. Put the camber at 2.5 and add cross till it pushes, then take a washer out. Mainly set the RF even with the RR, then adjust cross with the LF

That is the reason why you are loose center off. Go down to 1 1/8 and the numbers I suggested.
