My U295 has 6 new Koni's and 2 forward front Bilsteins. Seems fine. Any opinions? Previous owner did this
If you like the ride, why change anything?
My choice would be replace the 2 front with Konis,the 2 front/rear konis will wear out faster with the 2 old bilstiens,weather you like the ride is irrelavent,it will ride better with all the same koni shocks.
