I put SPI's in my ZRT and work well. Recreation Supply sells them here in S'toon.

Wiseco's are good pistons. Problem's you hear with these pistons all point back to not warming engine up enough. Forged pistons have to be warmed up properly or you will squeak em'. Every engine should be warmed up well, just it is a priority with the Wisecos.
