Baja Ron's Ultra Bar With End Links first and then tires. I saw the biggest improvement with the swaybar and some with the tires.
Here in Southern California, (I should say Calif in general) we have some of the crappiest

roads in the country; this setup really made a difference in handling and ride. On my Ultra Classic Limited; I completely went throught the suspension on it and it just glides the the road. It's a very smooth ride, but the Spyder has it beat. Rode a friends with shocks, and thought it was a little better than mine, but not worth dropping $750 - $1200 on shocks right now if you know what I mean. Still new to the Spyder and getting used to the handling in Canyons. I am an agressive rider and I ride both like I stole them, of course when the wife isn't on it
