I went with stainless lines on my VW because it was a show car...and ANYTHING was an improvement over the anemic factory brake setup!
But I agree with the posters here about the benefits of sticking to the OEM lines...and exactly for the reasons they mentioned.
But since my front-load Whirlpool washing machine doesn't have ABS drum control, I did opt for stainless steel braided washer hoses...too bad you can't see them!
