Recently I got my shocks (KYB-AGX) and springs (Vogtland) installed which dropped my 02 Honda Accord CPE about 1.6in. as stated but looks like the front is a lot lower than the rear..I'm guess 1.6in front and 1.25in rear. The problem I have is now I'm hearing "thumping" sound every time I go over bumps whether its small or large..The larger the bump, the car shakes even more....I have 17in rims on my car..Problem???
