It's the tires I'm tired of on mine. I upgraded the suspension with 300# t-bars upfront, five leaf springs in back and factory cop car front and rear sway bars. When I had 15" Radial T/A tires on all four corners it handled good and rode great. I swapped out to 18" Nitto 555 in preparation for a giant brake swap that never materialized and while handling improved even more, the ride quality went straight into the can. Not that I was surprised by it, but after a few years with it and dealing with Michigan roads I think I'm going to step back down to 17" or 16" wheels to get some sidewall back. Whatever accommodates the four piston brake setup I'm planning with 11.75" rotors.

Looking at cats for the exhaust too. While fuel injecting it helped immensely with the smell, it's still there and can become bothersome on long trips.
