I'm a newbie to anything that has to do with suspension.
So my big question is, if i get the tein-s springs for my 04 6MT sedan, do i need the shocks, any camber kit or anything with it?

Front ~ 1.9 and rear ~ 1.3 drop.

 

Technically you don't need to.... but some people like to do it all at once to save money in the long run. Factors to consider are tire wear, and costs of installation for each time if you're having the work done.
