I was reading some posts about lowering e55 and e500 and I was wondering if using the washers was the same on the e63. Also I was reading for the rear you need to cut a little. Is the the same for the e63? Is there another way around that? My only problem is that my car is under warranty and with my luck if something goes wrong with my suspension and I put it back to stock and they see a cut or notch they won't cover it under warranty. I was also reading about brackets that this company (tws) made that was $150 but if was only for the front. Did they make one for he back or does anyone know any other way besides spending $1500 - $2000 on a lowering module
