Ok so i'm putting 3 10'in jl audio speakers in a box in my trunk. I would guess that it weighs about 50 to 80 pounds...roughly..And I was just wondering what rear suspension setup I can use so my car doesn't sit different due to the excess weight in the trunk..I've seen it before on other cars. Right now i'm using the eibach prokit and kyb agx's. One of my kyb's in the back it shot so i will be replacing it soon. So while changing it i was gonna try and kill two birds with one shot..I looking for the same ride height i have now with the prokit.I was wondering using stock springs with the kyb's.Some one suggested coilovers but i don't really like those..any suggestions will be helpfull thanks...
