Ok I do not need to lower my car as alot of people would think but I do want to rise it up a little

.......Every single time I go over speed bumps I bottom out and scrap my undercarriage and I did have undercarriage lights on my hatch but not anymore for they broke when I went over the speed bump so now I am asking what can I do to rise it up a little maybe about an half an inch to an inch higher than what it is now and NO I am not a RICER...I had those lights on my car for show purposes...And I did not lower my hatch it came that way when I bought it last year from the GOSSETT Used Car Lot here in Memphis, TN....
