Shock absorbers KONI or GABRIEL

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.

I installed it on my RF and there are no issues.

I upgraded to Gabriel Strider shocks, best I could afford at the time, and bought Radial T/As to go on the Keystones. Big front and rear sway bars too. So even if my car didn't accelerate like a boss it did corner pretty well.

Got Gabriel on both my gen3s Self installed. They're as good as ya gonna get for these cars

I'd consider the KONI STRT if available for the 2012.

Bilsteins are probably best, unless you want to cough up a lot for fox. I have Gabriel premium right now. Pretty good, but not as good as Bilsteins.

If you want your car to float and drive like a boat, go with gabriel.
