What made you choose this particular product?
The Struts on my car failed and were causing some issues. I have always been one to buy factory or better parts. I chose Bilstein for their performance and quality that seemed to shadow the competition.
Is this your first time buying from this brand? Did you consider other brands?
This was my first time buying shocks, I did a lot of research covering all my options and Bilstein was the best option for what i wanted out of my car.
