With the help from Altian, I finally have the Koni installed on my 99 Sport. Compares to my OEM Bilstein, the Koni rides more "luxury" and more controlled. I tried both full soft on all 4 corners, and half stiff in front and full soft in the rear. I like both! Now I understand why the Koni cost more and is worth it. I am not sure if it is just in my head (after spending $$$), I think it helps with the traction in the rear.
Thanks Altian for his help!!!
