Piston upgrade for a 2013 pro/ with an slp stage 4 kit?

[DV-ENT]

Hello, I have a 2013 pro with an slp stage 4 kit on it with 1800kms, I can't instal the fix kits as they have base plates which won't work with the slp kit, I would like to go with a good quality aftermarket piston and am looking for advice and or suggestions and an approx cost. I live just outside of Calgary so someone local would be nice?

Believe RK tech has a drop in piston with better skirts.

Thank you both for the advice I will look into them. Chris do you carry either of the pistons you had mentioned? Or should one just order them online?
