The differential mounting bracket copper welding of this D8 is broken, caused by the forces released during firm acceleration. This is a known problem and the Donkervoort factory has an official reinforcement modification available without recall. If you own a high powered D8 (Cosworth, AGU and E-gas 210, 235, 270), the advise is to check on a regular maintenance basis if the brackets are not cracked on the copper weld. This can be done with a small mirror containing a led-bulb. In case of strange noises and /or vibrations; check this point on potential cracks.

The GTO has two struts mounted to prevent torsion in the diff bracket mounting points.
