I ordered stainless steel brake lines from Suncoast Porsche and realized they are manufactured by Girodisc.
Here I have some questions for you guys.

1) Is Girodisc a good company in terms of performance?
2) I got set of 4 for front and rear. The thing is, they all have equal length.
Isn't front brake line normally longer than rear one?
3) Do I only need one brake line for each side? Or am I missing anything?
They came with nothing. I got only brake line itself.

Any comments will be appreciated.
Thank you!
