Default moser 9" - best gear for given tire/wheel setup???

Ok guys I'm going to be ordering the summit star drag wheels 15x8 with M/T 26 x 10.5-15 ET Streets

At same time I'm gonna be ordering a 9" moser from EPP most likely.

My car is 98 ta full bolt on cammed a4 stalled 3600 3.23 stock 10 bolt and stock suspension for time being

I know I'm going to go with true trac over spool most likely but my question is which gear would best go with the tires?

3.89?
4.11?
dare 4.30?

The car is not a DD by an means, weekend car with some track time is all.

Any chance of the stock 10 bolt holding up under these M/Ts???

Thanks in advance for your input!
Geno

Need to know target trap speed and RPM. Plug those into a gear calculator and it will give you a good idea.

the 10 bolt(with a few tricks) in a A4 car will get you into the 10's reliably. if you pedal the car or use a transbrake, it will more than likely have problems at some point. it will get you by for a while at least if not abused.
