I have a 2001 Chevy silverado ext. Cab 2wd. Ordering a lowering kit tomorrow night. Need to know if I should get a 3/5, 4/6 or 5/7 drop. I don't want to scrap going in parking lots or over speed bumps or mess up my front bumper or valance. I'm going to ride on stock rims and tires for now till I buy some 22s or 24s. Any good brands that yall recommend and advice on what size drop? I'm thinking about 3/5 DJM drop as of now but don't know. Thank you for yall help I'm new to this stuff
