Well, my first set of Mahle rings I get through filing all eight first and second compression rings. I start the installation process and SURPRISE! the expander isn't the right one.
Mahale tells me 7-10 days to send me the right ones. Isn't happening. I have to have this done in 12 days and back in the car. Not particularly great customer service.
I certainly hope this isn't the standard for them. Summit will have to provide the right ones out of a set at the store. I'm not waiting.
