By memory supercheap dont stock the bushes, but they can order them in for you.

Dom EK yes the energy suspension hyperflex master kit comes with everything. with the civic kits they replace just about every bush in the front and the rear (spring mount bushes, control arms, end links, sway bars etc) I think the only thing it doesnt come with is motor mount inserts (which can be had for around $15-20 USD)

Have a look on www.energysuspension.com and search your application and you should be able to find what is included in the master kit for your civic.

Another popular bushing kit is the prothane kit www.prothanesuspension.com (I have a rear master kit on order for my accord) that are made out of nolathane, whereas the energy suspension kits are polyurethane.

Kenshin, no a new suspension setup with springs shocks wont replace all of your bushes, and dont kid yourself thinking its an easy DIY job.

You need to press some bushes in/out, which i doubt most ppl will be able to do at home, its a job for the pros in my opinion....
