Hey northerner ,
I went from KYB’s to Koni’s . I went with Koni’s with my ST springs hoping I could soften the ride for around town and be able to adjust up for auto cross . The Koni’s seem to be as stiff as the KYBS - at their lowest setting. Now - that being said - it could be my ST springs . Also, your car is probably heavier and with progressive springs you might be able to have a greater adjustability in ride .
