A period 1993 built and raced Mamerow 3.8 RSR with chassis number MAGT93001 and up-to-date Wagenpass.

Fast forward 20 years, the car had been in storage at Mamerow Engineering (ME). Peter and his son (now a works driver for Audi) decided to rebuild the car ready to race it together.  This was a ‘budget no object’ exercise, as ME had a substantial sponsor behind them.

This brought the car upto it’s current condition, where every aspect of the car was rebuilt or bought new from Porsche.  The list is extensive but to shortlist a few points; New RSR heads from Porsche, new BBS wheels, Fully rebuilt bespoke gearbox, new FIA bag tank, new AP air jack system, new drive shafts, new LSD.
A detailed photographic record accompanies the rebuild.

The car was loved by the sponsor so much that he refused to let the car be raced, and infact bought it out of ME for personal road use.  Since the car was rebuilt, ME ran the car in at the Nurburgring (500KM), and then the new owner covered 600km on the road before deciding that it is a bit too ‘much’ for the road and decided to sell it.

We inspected the car along side industry specialist Neil Bainbridge of BS Motorsport.  He regarded the car to be of the highest standard, and one that was “built to win”.

Neil is available to discuss any technical aspect of the car should you have any very detailed questions.  He is available at: neil@bsmotorsport.co.uk




Peter Mamerow created this car to compete in the 1993 ADAC GT Cup series against the factory RSR teams.  He raced with a good level of success, so much so that Porsche refused to sell him the latest RSR rear spoiler.  You can see this in the Wagenpass, and in the photos from the ADAC Championship.
A number of race result sheets are present in the file.
