Yes I was aware. I have a large file on Koni products from the 60's and 70's. Since my race car only weighs about 2100 lbs, the valving for the rear of the Camaro is about perfect for the Stinger. The 67 HiPo Dodge Dart I am restoring has Koni on it since new and I will be returning them to Lee Grimes at Koni in Kentucky for restoration soon. Logan Dernoshek ( Warren's son ) has driven my car at Mid Ohio, Watkins Glen and several other Vintage events and compliments my setup as very predictable ( and fast )
