2. The wheels and tires should be changed. The original factory is too ugly. 18 inch scissors, high imitation in Taiwan Province province, with original German S4 rear bumper and tail lip replaced. The domestic ones are too ugly, and the ABT ones are also ugly. After choosing, including taking some detours, I think S4 is the best.
3. Replace Taiwan Province Lei Xun 6-piston brake kit. ASPEC in Taiwan Province Province exhausts everywhere. The black roof is beautiful (like a panoramic skylight). The front lip and lower lip are painted black, which looks good.
