What made you choose this particular product?
brand perception of quality. Lack of too much fiddly adjustment.
Is this your first time buying from this brand? Did you consider other brands?
Not my first time buying bilsteins shocks, but my first time buying adjustable coilovers from them. I considered KW as well.
Was it easy to install? Any installation tips that will help others?
The install was fairly easy. To make the fronts much easier, use ratcheting wrenches with angled heads. When doing the install on a lift, use a jack to support the rear subframe when disconnecting the shocks and lowering it. Also, lube up the top of the rear shocks where the original components get re-used, might get a little noise otherwise.
Once you've had a chance to use the product, did it meet your expectations?
Absolutely. The springs are definitely stiffer, but they're also much better matched to the dampers than the stock setup, so the car is much less bouncy and therefore is perceived to have better ride quality while still being firm. Top notch product.

Any additional comments?
This was probably the most disappointing product i've installed. Biggest problem was that Bilstein clearly did not develop this kit. The spring rates do not match at all to the weight or weight balance of the car. They also used a poorly (yet strong) designed endlink mount. Beyond this, these are actually very strong and quality dampers. For the price they are not worth it, considering i have to spend another 1000+ dollars on new springs and strut plates.

Yes
Was it easy to install? Any installation tips that will help others?
Yes. Except for bottom rear bolts needed a 5 ft long cheater pipe.
Once you've had a chance to use the product, did it meet your expectations?
Great performance without sacrifice of comfort.
