To the best of my knowledge, the T1 sway bars only come with hard bushings. The front T1 a-arms come with bushings that are harder than stock, but not really what I would call hard. I don't think rear T1 a-arms exist. The rear a-arms use stock bushings.
For the sway bar, I don't think the bushings have anything to do with ride quality, they just provide support for the sway bar to rotate in without any other movement.
What you may be asking is what to use for the sway bar endlinks which are the part that attaches the sway bar to the a-arm. The T1 bars come with metal to metal heimlinks which work great, but are noisy. Some find this bothersome for a daily driver. I use them on the track. Others know of aftermarket endlinks which work but are lined so they are quieter. Hopefully one will chime in. If not, ask DJWORM. I'm confident he knows.
