Unique in a positive way, this tuning kit by the two companies is equipped with ADCV05 track rims, and they are enormous! The size of the front and rear rims are 9.5 21×12 and the tires are 375/20/21. This is indeed an innovation as we have not seen any tune for Mercedes-Benz cars that puts really big wheels. But who knows, Wheels Boutique might break their own record in the near future. But for now, check out more photos of the SLS AMG kit below.
