Rim sizw with a static drop

I am planning to static drop a '87 yota.
Want to go as low as I can.
How many inches can I drop it and what size rim should I use for this static drop?
Some people tell me 17"/7. Will the truck look low with this rim size?

I AM RUNNING 17 7.5 LOOKS GOOD.
IF YOU WANT 17'S GETEM IF YOU DON'T GO BIGER YOU ONLY WANT 2 BUY RIMS ONCE.

you only want to buy rims once, but when you get tired of them you will want something different. but yea 17s or 18s will work

go with 18's...i bought 17's and now im kickin myself in the ass because i didnt go with 18's.

I used to have an 86 with 18" Enkei Spiders. It was low as piss static dropped, I loved the way it sat. I had 4x4 fenders so I cant say if they wouldve rubbed on 2wd's.

thanks for all the info.
