Brake line question

[mustang_jr+]

I ordered new stainless lines for the front calipers as I had to replace one.

I bought these wilwood lines as they don't use the banjo bolts.

However wilwood doesn't make a set for the rear lines.

Don't the rear lines affect braking? (mushiness)
Why do so many places only make front lines?

I don't want to put on my new stuff to only have it feel the same
because of the stock rear lines.

Russell makes a rear hose but you may have to buy the set.
