I finally got my 99 t bird on the road enough to find some things needing upgraded. One is replacing the too soft foam in the seat. I know a local person that can do that for me. Next thing is suspension, I see Hyperpro has a street box that has fork springs/oil and rear shock for a reasonable price. I'm looking to get input from the forum on other options. Thanks!

The Hyperpro kit is good but you could probably achieve about 80% of the upgrade with a service, pre-load spacers, and one step heavier oil. The rear shock is only pre-load adjustable so a replacement after-market unit is the way to go.
I put in a YSS shock and with the riding I do on the 'bird (mostly cruising, unless on a narrow twisty road) I am well pleased. If the Hyperpro is within your budget, I'd go for that. Have one on my Ducati Desert Sled (ridden much harder) and I'm really happy with it.
I put a YSS on a Versys I had, it made a big difference, much better than stock. Thanks for the suggestions.
I have a 1996 Thunderbird. OEM triumph rear shock was HORRIBLE!! I have a thread on this site about swapping in a Kawasaki ZX9 rear shock that has a remote nitrogen reservoir with BOTH compression and rebound adjustments. If I remember correctly- the shock was from a '97(?) ZX9- you'll want the one with the hose that goes to a remote reservoir- the shock was a used $40 Ebay find, the "dog bones" were nice, polished alloy used items with 3 different holes to adjust ride height, (the ZX9 shock is longer and raises the rear end) -$20 or so, a bladder rebuild kit for the reservoir and a $20 "tip" to the local dirtbike shop for a nitrogen refill while the tech was on his lunch break. Since Kaw and Thunderbird weigh about the same, I used ZX9 spring. ETTING "SAG" IS ESSENTIAL!!, but easy to do. Total investment about $125- WORKS LIKE A CHARM!!! For front- springs from RaceTech calibrated to my weight and some slightly higher viscosity fork oil did the trick.
That should be "SETTING "SAG" IS ESSENTIAL"
