wsm pistons

[hillbilly09]

are the wsm platnum pistons any good

 

[yzrider]

i'm gonna say no, looks to be a cast, not forged, buy a wossner or weisco forged piston...

 

[hillbilly09]

wsm say hardened aluminum

i think im going to go wiseco just looking around for the best deals

and wossner and wiseco about the same?

They are fine if you are not stressing your engine by racing. Also you have to make extra sure that everything is spec with you motor, ring gap, oil level, ratio's, ect. Wiesco pistons are much more reliable and are really worth the extra few bucks.

wossner uses smaller rings, but mainly the same, yes
