Hey out there. I need some help I don't know if these wheels will fit my clk 320. They are the stocks off a sl 500. The fronts are 245/40R18 OEM , 18x8.5 , ET25 (R129 AMG I 5-spoke Wheels). And the backs are 275/35R18 OEM , 18x9.5 , ET23 (R129 AMG I 5-spoke Wheels). I don't think the offset will work. My offset is 37 on stock wheels. Please help thanks.
