I'm still out on the Dynabeads thing.
Too little and they won't work. Too much and it may be the same. No?
Seems you need to be pretty close on how much of them you'll need to add.
I did the liquid sealant thing in my car tires and it hammered bad on the road at 40 mph. These were already balanced (with lead weight) tires. It did get better at 70 miles since the add (they say 50 miles), but there are times it just shakes still - other times not so bad.
The beads may congregate at some point and not move, like an internal molding junction of the rubber.
I don't know. Just some thoughts.
Regarding the jack, I ended up getting both front and rear PitBulls. When I use the front only, the thing begins to fold off the centerstand if I don't let the stands wheels roll towards the rear. Seems I forget this every time I use the stand until I see the centerstand begin to fold. Now I use the rear stand as well.
The GT costs big dollars no matter how it falls, worse on the right with the cases off (muffler and more front cowling area damage).
