I noticed that the 4-way adjustable headrest were an option on the 03-04 GTs and standard on the Mach1, Cobra seats. Since I'm rather tall for my 04's seats and concerned about neck protection, maybe I could get the needed neck protection by just swapping headrests instead of doing the S197 seat swap?

Can the 4-way headrests be adjusted in different forward positions or is there just one adjustment?
