from the owner:
So the car went to Werk 1 and started life as a Special Wishes order,with the most "common" mods of 330HP engine which needed the different front valance with front mounted oil cooler,Adjustable wastegate,Boxed Rockers and Rear Guard vents. It also got an 8/37 Ring and Pinion for quicker acceleration,an LSD,Bigger Torsion bars and stiffer shocks. It had full leather trim from new,but they cut the belt holes into the seats at the factory,a really rough job,too!
When the car was finished it was picked up from the factory by Kremer and taken back to their race shop where they fitted the intercooler and the kevlar spoiler. They may have put an exhaust on it as well,but i'm not positive about that.
It then went back to the factory where it was delivered to Bartels as a Tourist Delivery.
