Owner reviews for shock absorbers

I have the entry level E46 Ground Control setup that includes Koni shocks. It's a vastly superior ride to the bilstein PSS kit I had before this but the kit is not perfect

Koni yellows are adjustable to suit your preferences. Bilsteins are not. Both are high quality and arguably an improvement over the stock (Sachs probably) dampers. I run my Koni yellows on full soft and they’re very comfortable.

I love my Koni yellows but I do drive them on their softest setting.

I struggled with the same decision for my 2002 325i, We've used Bilstein sports for many years but always for sportier cars +/or track use. On the E46 decided to go with Koni Sports (yellow) which are adjustable. Ride is less harsh the Bilsteins, more comfortable and well controlled - no regrets. I also installed H&R sport springs FYI.

I love my Koni active reds, swapped to them from bilstein b8s and won’t look back, smoother ride and 4 years on them they haven’t sagged or blown. I run them on my daily e92.

Both great, sounds like you’d do well with boosting B6. Sporty and an upgrade without being harsh. We have them on my wife’s c5 Vett and she likes them

Some people say Bilstein 5100 remove nose dive, but I disagree - the 5100 help, but you still nose dive.

My 325 ix was lowered by the previous owner on Bilstein and h and r sport, but it is a harsh ride.

I had Bilstein, but they broke after just 2 months.

Dont go Bilstein 5100. They rode nice at first, but then rough and didnt last long.
