My honda civic

Hey guys,

I have a 94 honda civic couple. I'm thinking about geting 17's with 205/40 v rated tires (maybe z). How much shoudl I lower it?
Benefits? Anything I should watch for?

I'm thinking of getting the Eibech pro kit, or maybe sports line. Is a 1.3" drop enough to make it look good? I don't race with it, just street use.

THanks
