Question on Cylinder / Piston replacement

[Marcusknight23]

Take a look at this for me. With this option, you exchange both the cylinders and the pistons. Yet it still asks for a Bore size. Does it really matter which one you choose since I would be replacing both pistons and cylinders together? How do you choose?

It should not matter as they are providing the bore and pistons.
It is SBT though so you get what you pay for.
You could always call them.
