I did the CHF front and rear, SafeTsteer and the Koni's all at the same time so it's hard to narrow down to just the shocks BUT it really made the ride so much smoother than the Bilstiens. We have a mountain pass close to our house with a very rough road surface expansion joints and pot holes and the ride was vastly improved. We can still feel the bumps but not like the old shocks. Koni's have a completely different valving system than the Bilsteins, Monroe and Sachs so you pay more for it. I fortunately have the income to be able to afford the better technology in shocks.
