Another BTW, on your photos I can see that your Plus 4 is hanging a bit backwards. If you are using lowering blocks I would think about removing them or use thinner ones to get the view straight. You have more suspension travel and a straighter line. In addition, the rear axle is "in" the spring and not "above" the spring. This eliminates or reduce the negative leverage effect on the spring in the event of lateral forces when cornering. Even if ghe rear comes a bit higher the ride feels more controlled. At least this is my experience.
In case you would make the lowering blocks thinner or remove them completely (depending on how thick they are at the moment) half of the sandwich rubber has to be removed over the axle to still allow the car to swing out properly.
I wonder if that enormous suit case and camping equipment on the luggage rack is responsible in some way?
