im kinda new to offroading and zuki's but im looking at a 87 sammi with a 2inch reverse shackle lift and 31's they look like they could scrape a little if i tried to flex on most stuff. If i was to wheel it should i go back to the stock tires or not? also if i was to get a rear locker should i try to save money on a detroit e-z or should i just get a regualr one

Welcome to the BBS  

The EZ lockers are as cheap
as a locker gets, I don't know of
a clutch type locker for a Suzuki,
but there are air lockers out there,
about $600-700
