20 12 BMW 530Li changed the wheel hub.

If you want to change big tires, you'd better wear 19 inch.

The wheel hub price is about 1k5, and the tire price is about 1k5.

I recommend you to change the negative wheel hub, which is more handsome.

And it is best to replace the shock absorption system of the car.

Replace it with twisted teeth to reduce vibration and adjust the camber angle of the rear wheel to achieve the effect of outward figure eight, and the price is about 8k.

There is no point in changing tail gas, unless the whole tail section and three-way catalytic converter are replaced, and the price is about 3k.
