The offsite difference is a little less. I am thinking about a compromise. I will replace the lower 3 washers (4.5mm) with a 3mm thick piece of alloy. On the top i will remove one washer. In addition i will remove the washer under the bolt head. This will result in 10mm space between the leaf springs and the bolts. I can only hope that in combination with the Panhard rod this will be enough.
