First of all, G500 can upgrade the original brake caliper of G63, or upgrade the brake caliper of the old AMG6 piston. The difference in appearance is different, but the difference is not big. The new size can be larger, and the brake discs are different. The new G63 was originally red, but it was also changed from gray to red. It's over 8 thousand short. At present, the market is basically gray to red, and so are brake discs. The difference between the original brake disc and the domestic brake disc is nearly 1 0,000. You can let the store match it for you according to your needs. The original brake disc is definitely better than the brand one, but depending on whether you can accept the price personally, I will choose the brand brake disc. I've been using it for almost four years now. I usually drive in a calm way and the brake discs don't shake. I bought the parts from Deli Automobile Company in Tik Tok Dalian. His home is.
