STI 7 forged piston markings
 

just a quick question- do they sti7 forged pistons have the grade marking on the crown like the wrx cast items, i.e. A or B depending on bore size? or know where it is, many thanks :thumb:

Yes - grade/oversize markings are on the crown of the pistons and can be found above or below the horizontal band across the crown of the piston.
