Hi Tony.
The B6 (laydown) transmission seems more popular on the super high grip indoor tracks. However, I would probably do the following:

Go to a stiffer Spring all round (red front, white rear).
Go up 2.5-5wt thicker shock oil all round
Take some weight out the car to give a little more reaction (try with and without).
Reduce downtravel/droop a bit (maybe run another limiter under the piston).
Run the gear diff if you are not already.
Go to the lightweight/v2 slipper setup.
Run minipin rear tyres (I would avoid the new minipin 2 and minipin 1 tyres, get the original minipins if you can.

Or try the proline pinpoint/wedge and the new JConcepts tyres that have been released.

The limiting factor is the fact you will be competing against the laydown cars which carry much more corner speed in smooth and high grip conditions.
