ok guys I'm about to buy my piston and need to know a few things,first of all I have a vitos 240 bbk on it's standard piston,now I've been told to run the wosner piston but I need to know where to get this piston from? every time I type it in LA-Sleeve pops up? is that the piston? also can that piston work with my bbk? I know vitos now has the 72mm forged piston back in stock should I just get this? like I know the vitos ring gaps are on the intake windows as for the wosner I have know idea,if anyone knows this piston headache please set me straight,again thanks for all of the help fellows
