The biggest thing you can do to help traction is increase tire height followed by width, if you want to keep a tire that retains decent handling and wear. The taller tire will effectively lengthen your gear ratio which will soften up the torque spike when you hit the throttle.

Sure, you can move to a 17" with a super soft tire like an ET-R, but it's not going to be as stable, nor handle very well, and the street will tear up the tread fast.

Beadlock is just for show and adds weight. No need unless you plan on going to the track and hooking the car out of the hole. You are not going to spin the tire on the rim from rolls unless maybe you are 1500+ whp.

All that being said, 900+ whp RWD vehicles don't hook very well on unprepped surfaces period. Ultimately you may end up needing some sort of boost control logic like the Smooth boost. I believe DSX also offers something that provides control over the 2650 bypass valve so it can be set to close slower.
