From Eibach Pro Damper to Koni Street.t, same result... Good ride for 6 months and then the ride starts to deteriorate to riding on the springs at the end with no more than 12000 miles (ridiculuous). What s next? Maybe I ll try the Bilstein HD. I already tried Tokico, AGX, KYG... I learned my lesson, on my next car I won t mess with the suspension.

I purchased these from Tire Rack for my girlfriend s 330i sport sedan as a OE replacememnt. Partly because of the cost and mostly the brand. I have been nicely surprised on the ride quality and performance. Everday driveing is excellent and even ran the car at Friday night drags at Atlanta Motor Speedway. They do an 1/8 mile run pinks style on pit road. So squat was definitley reduced on those runs and dive while under hard braking. Also I was able to do the long course at Sebring while at a Porsche club event with a friend. They let you do some pace laps but everyone fades back so can see what their car has and these shocks were very good especially if you know Sebring, its bumby in many spots but these did a great job on both the smooth and the rough stuff. I just purchased a 2004 330i ZHP performance package and these are going on it. They are a great value and more than good for track. If you can afford to do alot of track and have a second car then you can opt for a more aggressive package.

Absolutely disappointed!!!

I installed these 2 yrs ago and the rear has already failed.

They are fully compressed and have zero return.

Even when they were functional, the slightest crack on the road was felt.

Spend the extra $10 and get a far better product.
