The OEM are mfgd' by Bilstein. I installed the Koni because at the time, they were the only ones available aside from Bilstein and I have had good performance in the past from Koni Sports. Now however, I want to try the KW Variant 2, But the spring perch needs to be modified to make them fully adjustable. I ran into a KW engineer at the track a few weeks ago and he said that he could probably modify the set-up to use the KW Variant 3, but that would take some serious cut & weld.
The Koni's have been really good on this car and made a huge difference from the OEM.
