The BMW E87 1 Series remains one of the safest small cars available on the market. Part of the reason for that reputation was its braking performance. But brake discs can easily become thin and worn when used in stop-start city traffic. Restore the factory braking ability in your 1 Series (and with it, your confidence) by replacing the worn front discs with these brand-new items from Zimmermann. The discs feature their own special Z-Coat technology to prevents them from rusting. Zimmermann are an original equipment supplier to BMW. Made in Germany.
