There's a few size combinations that might work:

F: 225/50r16
R: 245/45r17
The 225/50r16 is very tall and requires a taller 245/45r17 to maintain an appropriate tire size ratio. (3.1%, compared to 5.2% for LSS) You're also pushing the boundaries of fitment with stock fenders.

+1 sizing
F: 215/40r17
R: 255/35r18
Almost the exact same rolling diameter and F/R ratio as standard LSS. But, most people don't want to run 17/18's.

-1 sizing
F: 205/50r15
R: 225/50r16
The 205/50r15 is small, just over a half inch in diamter smaller than a standard LSS front. But, when paired with the 225/50r16 it has a 7.1% size ratio, which is acceptable.

The Bridgestone RE-11 should be a better fit in the extreme performance tire category. They have a 205/45r16 and 245/40r17 which is just about ideal. Tire performance is almost identical and comes down to driver preference.
