Thinking about purchasing a set of older Brabus Mono V 19" 2 piece 19x8.5 and 19x9.5 for my 04 CLK55. I was wondering if the front with 35mm offset would fit without spacers, because the wheels do not come with spacers and only hub-centric rings. Brabus does recommend 5mm spacers upfront, but then again they put on spacers on every wheel for every car just about. Our current 17" wheels have an offset of 37mm upfront. Do you guys think I will have a fitment issue with my calipers? Anyone else running custom wheels with 35mm ofset and no spacers without issues on CLK55? TIA

Most likely you're going to have to test-fit the application. The 55's have bigger brakes so you'll want to make sure that the Brabus wheels will still clear without running their mounting kits. ET35 does sound a bit high for a CLK55.

Stock 17" upfront are 37mm. But yes, I guess I'll just try to test and see what happens.
