Prothane bushes need lube and may become noisy after a while, unlike the stock rubber ones.
Twos'rus kits are ok to fit, but get the right swaybar bushes for your model.
The hardest to replace would be the lower control arm bushes.
Some people press the old ones out, others burn them out.
For more info, ask google.
If you you are ordering from twos'rus, and haven't already done them, also consider getting ball joints and front tie rod ends, both inner and outer depending on the condition of your old ones.
Also, how good are your swaybar endlinks?
