I was looking at the overboost website and found the follwing and was wonderin if these products are worth to get:

Energy Suspension Tie-Rod Boots
Energy Suspension Front Ball Joint Boot

would these even benefit or do any type of handling improvement on my 97 Civic?

 

A boot won't do anything for handling, it's a protective cover. Bushings on the other hand are a good thing for handling.

 

I used the tie rod boots when mine ripped. My tie rods began rusting and failed quickly afterwards......

 

A polyurethane boot might last longer than rubber, and be stronger. It won't help handling. Polurethane bushing set will help handling by making various suspension parts deflect less when turning.

 

you should have regreased the joints. i've had prothane tie rod and ball joint boots for a few years now. no problems.
