I got that crap alot with some of my friends. I'd meet up with them and we'd decide to go somewhere and everyone will be like "we're goin int the cobra!!" i'm like no guys im not stuffing all four of us in there and they'd just overule me and we'd all shove ourselves in there like we were in a clown car. Since the car is lowered on Sportlines, it made my tires rub and my stock shocks could not handle that kind of weight so it felt like i was riding only on springs. I felt like i was damaging something in the car so later that day i just took out the whole rear seat. It wieghs about 25 pounds; no big deal but things add up. A little here, a little there and it all adds up. I took out the rear seat; didnt put a cover on or anything cuz i dont really care. Took out the rear trunk cover, the jack, spare tire, etc, and the AC so far. So thats 100 pounds for the AC, 25 for the rear seat, and around 25 for the jack and spare. So little by little i saved 150 pounds and thats significant. I say do it.
