9 Seconds in a M6

What mods are you guys doing to your M6 to get down to 9 second range? I'm at around 850 whp now, but soon to be running on E85. With the E85, I expect to be mid to upper 900's at the wheels.

Transzilla? Tick Performance? Which gear setup are you using on 1st through 3rd?
2.98/1.78/1.30/1.00
2.98/2.10/1.43/1.00
2.66/1.78/1.30/1.00


I have a carbon fiber drive shaft, 1400hp axles, rear differential brace with stock rear end ratio. Upgraded clutch to 1000 hp double disc.
For tires, 17 x 10 bead locks with MT ET/r 305/45/17 with skinny front runners.

Any other input would be MUCH appreciated.

Thanks in advance.
