back tires rubbing on civic

[krz2fer]

92 civic lx...

I used to run on 205/40/16 tires but the treadlife was too short for my budget, so I upgraded to some BFG 205/50/16 that had a nice warrenty with them. And of course TireRack said they'd fit fine despite some hesitation on my end, so I got them. Anyway now with 2-3 people in the back seat the back tires rub on the wheel well lip on the outer edge of the tire. It's not a big deal right now but it's not something I can keep letting happen because I don't want to blow out a tire eventually.

I'm headed on a fairly long trip in about a week and I need a fix here since I'll be taking 3 people along. I've heard from a lot of people about those spring spacers you can jam in there to minimize give, so I got some today at autozone and found out that they cant be put in unless the springs are removed and uncompressed a bit - something id take to a shop to do since I dont have that kind of experience.

I've also had suggestions to get stiffer springs with minimal drop like H&R OEs or Sports or something, but I know new springs on stock struts can be bad. So any suggestions here.. ?
