I have the RCD Bilstein shocks on my '69 Convertible. It has stock R/T rear springs and sway bar, stock front end and sway bar, and a slightly larger 0.96" T-Bars. It rides good, not real stiff. I thought the shocks would be a bit stiffer like the KYBs on my Charger.
For my stock suspension, I should have just used the KYBs and saved $300.
