For those that know, the E30 3 Series is all about a light-weight, balanced chassis. The car developed a cult-like status amongst enthusiasts due to its driver involvement and the sheer fun it can provide. Confidence in its braking ability has always been a key ingredient to the E30 recipe, too. But when the rotors wear down, the braking performance of the vehicle diminishes. We recommend replacement discs from Zimmermann, an OEM supplier to BMW. Made in Germany to the highest standards, these discs are the perfect replacement for daily duties or more spirited driving situations. Priced by the pair, these discs are also treated in Zimmermann's own Z-Coat technology to prevent the usual unsightly rust around the hubs.
