Absolutely one of the best upgrades I’ve made to my BMW. The pedal is noticeably firmer, brake feel is much more consistent, and the confidence it gives under hard braking is worth every penny. The quality and fitment were spot on. If you’re on the fence, don’t be, the four outer lines are honestly a walk in the park if you can hold a wrench. The only real challenge is the two inner rear lines above the subframe. If you’re tackling those, do yourself a favor pay someone else. It’ll save you a ton of work. Highly recommend these lines to anyone looking to improve their braking system!
