Ring lands are best described as the area between the grooves the rings are installed in and the top of the piston. All pistons that use a sealing ring will automatically have ring lands. The thickness of them (as well as the constuction of the piston) will determine their strength.


Are you sure you know what you're getting into? Like has been said, the SZ55 and the FP Red are not really daily driver friendly and require a lot of supporting mods. If I may suggest just getting a EcuTEK flash and a turbo back exhaust and then take some time thinking about what you really want from the car.
