Brake lines for S550 4 piston caliper swap

I’ve looked through lots of threads but can’t seem to find my answer. I’m gathering parts for the brake swap on my 07 GT to the base S550 4 piston calipers with the 14” GT500 rotors, and I’m not having any luck figuring out which stainless brake line kit I should order. Any suggestions? Pic below are the S550 calipers that are on their way.

Out of curiosity, why didn't you opt for the S197 4 pot? they're a plug and play ez pz swap, and there's the stainless braided line or the boss302 lines you could use.
Mostly cost and availability. The Boss 302 calipers aren’t as cheap as the base GT calipers on the s550, and given their uniqueness, pads are harder to find in my part of Canada. But I can always get base model S550 stuff here. And they are pretty much a bolt on fit, just need you adjust the hard line portion of the flex hose.
