Remove two of the four wheels that are driven and see what happens.
Off into the boonies at great speed.
I repair TT's S3's RS4/6's Porsche's etc and they are great fun to drive (legally
) and some are turbo'd and they can be driven off silly amounts of boost with variable vane technology but they weigh as much as a small bus,put large amounts of power into a 6/700kg car and you have the big brother of Frankenstiens monster,great for the track but if you want to spend your time in a field or ditch buy a tractor,you will spoil not only hours of hard work but also a fantastic sports car you have built.
Just my humble opinion.
