Weight reduction

The ST185 is the heaviest GT-Four made - my Carlos Sainz weighs in at 1450 kg according to the chassis paperwork. Weight kills performance, hence I decided to take unnecessary weight out of my car. Below you find a list of parts and their weight. I'm not saying you can just remove these parts for better performance, but it might help you better understand your car's weight (distribution).
