I'm looking to buy a crew cab and sell my single cab and my daily beater s10 so I can buy a crew cab, wanna lower it 4/6 or 5/7 on some Sierra reps, gunna do a 20 with a 275/45 tire, what kinds of issues or things do I need to watch out for goin that low? I ideally want to do 5/7 cause the roads here in Missouri are pretty smooth and I love that low static drop look, but just want to know what things I could encounter and what I may need to cut or modify to make it fit
