How hard is it to do this and is there a site on how to do it and is it worth it?

 

not worth it if you ask me. for the cost & effort your braking abilities will not increase significantly. Now, if you are worried about looks then go for it.

Just rebuild your drums. New cylinders, spring kit, shoes, and get the drums resurfaced.

 

For the sake of maintence I hate drums. All you need is the rear trailing arms complete with rotors and calipiers off a 90-93 teg or 90-91 crx Si. They bolt up like stock and work great. I just really hate drums personally. I got the complete setup off a 91 teg for 150+shipping.

 

maintanance wise drums are more difficult, but you have to change them 1/2 as much.

 

I got a free rear disk conversion so I am doing it asap, I hate the way my drum brakes squeak. No matter what I do they squeak a few weeks later!

 

I've still got drums on my 89 si, but i plan to do a front big brake kit so i'll switch to rear discs mainly for looks as they do not help braking much / really marginal
