Does anyone know if the E550 caliper mounting points are the same as on an E350? Same chassis, same year. I noticed that the E550 has 4 pot fixed front calipers but the E350 has 1 pot sliding front calipers. Was hoping to upgrade with as little modifications as possible and if the mounting points for the calipers are the same then it should be pretty much plug n play?

Thanks in advance!
