As is typical with the internet, this thread is full of people with zero experience telling others with experience all about it.
Yall can believe what you want. I've actually used braided lines on three cars. My comments are above.
@TTiimm I agree with you getting braided hoses will help. And not mutually exclusive. Just pointing out that Pads offer the most dramatic change/improvement vs braided hoses. The reason I went with organic rear pads on the BMW was the Double H sintered pads were eating rear rotors. Let's just say without trying very hard on average sitting riding, I can easily bring the BMW to a stop with just the rear brakes without trying very hard.
We understand that going from sintered to organic rear pads on your BMW made a more dramatic improvement than did braided lines.
That's fine, but the topic isn't sintered vs organic brake pads or BMW's.
The topic is braided steel brake lines on Foresters.
On topic: I have braided lines on a Forester. I have actually done it. It makes a noticeable difference. Whether the difference is worth $115 for parts and time to install is up to each person. For a performance minded driver who is doing a brake job with other premium parts, I recommend it. That's all.
