I am learning more here every day. Some of the handling and cornering knowledge that I have began with my interest in Camaro/Firebird models back in 1986. Those cars are vastly different, but some principles do apply.
Regarding the K member and it's role, some members here, but not all, believe that some very simple modifications can be made to it to improve the car's handling. Some areas of the K member need to be better supported with better welds and more bracing. These mods are thought to increase durability and steering response.
