I upgraded the brakes on my CLS400 and so can you. You can make these upgrades with various models; from C300 to C43, E350 to E550 / CLS550, and more! Just make sure all part numbers coincide. Any 63 model upgrades (ex. C63, E63, G63) may require adapter brackets to mount the calipers, as well as additional changes. Upgrading to a higher model's, however, is not nearly as pricey, as well as provides a significant improvement! In the case of these 550 upgrades, the rotor is in fact the same size as the 63 models, with the exception being the 2-piece upgrade.
