I've got a 1996 xjs conv with the 4.0 aj16 eng. I was wondering if anyone has upgraded their brake and or suspension systems on this model and if so how they did it, what parts they used etc. I've seen some suspension parts on the driven man website and i wanted to know if anyone had any experience with them. Also has anyone been able to install brake systems from a newer xk or maybe a db7, something with larger rotors and better calipers? Any help or input would be greatly appreciated.
