The Golf RS1 project car started in 1998 with an empty Golf IV body in the workshop. The brand new body was completely stripped with a new floor, new front and rear subframes and a roll cage. Everything was built from chrome-molybden pipes. The wide kit-car flares from VW Motorsport in Hannover provided enough space for big rims and tyres.
The rear subframe and suspension is a mix of Audi RS2 and Sport Quattro with titanium swaybars and magnesium suspension struts. The front subframe is custom built, also with titanium swaybars and magnesium suspension struts. The exhaust is built from 4.5" stainless steel pipes all the way from the turbo and back with a single muffler under the car. The transmission stems from an Audi IMSA car with a custom built final drive.
To further reduce weight, many of the stock parts were replaced by correspondning parts made from carbon fibre. For example, the instrument panel, door trims, hood and bumpers were all replaced by carbon fibre parts. The stock seats were removed in favor of Recaro carbon fibre sport seats with 6-point harness belts. All windows are made from lexan plastic.
The stock 1.8 litre engine was replaced by an inline five cylinder 2.1 litre Audi turbo engine with two large intercoolers. The engine develops about 600-900 hp depending on the choice of turbo and setup. To make room for the larger engine, the inner fenders had to be replaced by chrome-molybden pipes.
The larger engine did not leave any space for water or oil coolers in the front of the car so these had to be moved to the back with an air intake in the roof. The car is equipped with Alcon brakes with 375 mm front rotors and 355 mm rear rotors. Thanks to the wider kit-car flares, it is possible to use 10x19" rims with Bridgestone 265/30-19 or 12x20" rims with Bridgestone 285/30-20. The overall weight of the car is about 1440 kg.
