I have bmw 320i e-30, and i need to change the rings on the pistons in the cilinders so i wonder cuz there are difrent types of rings which is the standard for for piston with dimensions 79,98.2. And also how much should be the clearance on the piston in the cilinder. I hope someone can answer this thanks

std piston is 79.98mm so order std piston rings

i think piston to wall clearance is between

0.01 to 0.04 mm

hope this helps
