What made you choose this particular product?
The roads in the UK are very poor quality so the aim was to improve the ride quality over the OEM suspension whilst increasing road feel and handling characteristics. The PSS10s were modified to allow additional suspension travel at low ride height. This in combination with the other chassis modifications allow for a very competent 'fast road' set up, confidence inspiring even on the worst road surfaces.
Is this your first time buying from this brand? Did you consider other brands?
I considered Nitron and Intrax however they were much better suited to track application so opted for PSS10 for the road

What made you choose this particular product?
Bilstein and OE are the only options available for EDC equipped cars. Bilsteins are also considerably cheaper than OE and their B6/B8 line is better suited to performance vehicles with lowering springs.
Is this your first time buying from this brand? Did you consider other brands?
I've ran Bilstein's standard B6 dampers on my 2012 328i with great success. No other brands were in consideration because OE is the only other alternative.
Was it easy to install? Any installation tips that will help others?
Easy install in my garage by myself with basic hand tools. Take your time. No spring compressor or anything extra was needed.
Once you've had a chance to use the product, did it meet your expectations?
Performance was far above my blown out 127k mile factory shocks. Toggling the EDC modes makes a noticeable difference in softness. Comfort mode is still very well absorbed. Normal mode is firm, but not harsh. Sport mode is stiff, but also not harsh. It's great to have a usable suspension again! As for handling and track use, I'm now able to get on the throttle earlier and put the power down. Far better than worn out OE dampers and willing to bet these are way better than new OE dampers.

What made you choose this particular product?
High quality mono-tube shocks with adjustability that makes it perfectly drivable on bumpy roads as well as track.
Is this your first time buying from this brand? Did you consider other brands?
No, I have used Bilstein products before on both street and race cars. I looked at several other brands but quality and potential longevity of these coil-overs is what sold me on them.
Was it easy to install? Any installation tips that will help others?
Yes, straight forward install, just followed the Bilstein instruction in combination with the Volvo installation guide for suspension.
Once you've had a chance to use the product, did it meet your expectations?
Yes, worked as all bilstein products have in the past.
