I have a problem. I would like to replace the front and rear suspension on my Skoda Superb with Bilstein B4 shocks. However, the car parts seller is telling me that Bilstein does not make B4 shocks for my car. What should I do in this situation? Are there any shock absorber models from another car, for example Volkswagen, that would fit my Superb? My rear shock absorber part number is 3Q0513049FP, and my front shock absorber part number is 3Q0413031CQ. What would you recommend? Also, I have one more question: do the other parts, such as the strut mount kit, dust cover, and lower spring rubber and etc, also have to be Bilstein parts, or can they be from another manufacturer? My car is a 2021 Skoda Superb Sportline. Thanks in advance! :)
