Are you running the stock suspension? I only ask because worn rear shocks/springs will allow the rear end to sag, lifting the front end to exagerate the gap up front. This is how my car sat before I did the sachs lowering thing. I believe this is why many (including myself) see a greater than 'advertised' lowering in the front end, and even a rise in the rear (which is why I post this for you). My ass saggedbefore the operation and was lifted noticabely after.
By firming up the suspension, it may even out your stance and solve the problem.
