Hey Earl,
There are a few combos I've had good success with this last season on black carpet.
-A30/A30 (basically pink front and rear)
-A32/A30 (Magenta front/Pink rear for a little more entry steering. This is my go to most of the time)
-A32/C30 (Magenta Front/Green Rear locks the car in a little more overall)
-R35/R35 is pretty popular in 13.5. This is like a super blue
.
-Korey
