Today wosner for a client arrived and could compair them to my fcp.
Do not know what to say.Forging marks more visible inside fcp,wosner are more machined on the inside.FCP has slim rings compared to wosner.What should be +/- of ring height?FCP is covered all in a grey treatment,wosner only skirt.FCP slightly easyer and both type of pistons weight the same compared to theyr other 4 in the set(1g precision of my scale)
Both have same number of lubricating holes,no sharp edges on both.Wosner + for more detail on stamping manufacturing lot(i guess)and part number.
What do you think?
