What made you choose this particular product?
I've had Bilstein shocks on a previous vehicle and enjoyed the ride. The quality was good so I stuck with the brand
Is this your first time buying from this brand? Did you consider other brands?
No, I had Bilstein shocks on my previous vehicle.
Was it easy to install? Any installation tips that will help others?
Had no issues with the installation at all. Very straight forward.
Once you've had a chance to use the product, did it meet your expectations?
Works well when lowered, a little rough if you only lower the car a minor amount.

What made you choose this particular product?
Previous good experience, needed something to match better with H&R springs. Also like that I can send for rebuild/custom valving.
Is this your first time buying from this brand? Did you consider other brands?
Not my first time, considered other brands or full coil over kits, but went with these for better ease of use, lower maintenance and streetability.
Once you've had a chance to use the product, did it meet your expectations?
Absolutely, felt better than the B6 version of Bilstein struts I had previously and I suspect will last longer as well.
