wsm are the same as prox but they cost about 2/3 the price, but since this is sbts sit i would say go with there pistons, i have never tried them but i have never heard or a problem. and they have that life time warrenty, does wsm prox or wesico have that?

WSM are no where near Pro-X, they are a totally different design from one another, as are Wiseco. Ours are designed after OEM dimentions, with a hard anodizing top-cote.

Wisecos have an advantage when running a superstock motor, on the edge of the performance envelope. They are stronger and lighter, HOWEVER require greater setup detail and greater use attention. They are generally not the best for the average recreational rider who may at times gun it without fully warming up the engine, or the average builder who will not know the proper clearance to build with.

Prox is a good design, with a slightly built up crown area, but are close to OEM. We used them early on, deciding if we could use something existing on the market, or if we needed to manufacture something ourselves for the best results. We found that the only brands out there that gave us hassle free results were OEM, so we made our own to the same specs.
