WEIGHT: 1190* KGs

295 BHP Per Tonne

Weight is reduced to 1,190 kg dry, 1,220 kg wet, down from the original 1,370 kg of a standard 993 Carrera 2.

With 270 bhp per tonne, it has the same power-to-weight ratio as a 996 GT3 with its current engine. However, the spicier 360 bhp option, offers 295 bhp per tonne versus 293 bhp per tonne of the 997 GT3.

*Dry Weight

Seam Welded  Body

Integral Roll Cage

5-Way Adjustable,

Active Suspension

Like the original Autoart 300R created some 20 years ago, the 993R delivers a more focused driving experience than the original car it was based on. With a seam welded body, integral roll cage combined with five-way adjustable, active suspension and Porsche Motorsport components the 993 chassis delivers a visceral driving experience.

Hand Crafted Lightweight Interior

While performance is important, the 993R also features a level of driver comfort that would be expected today. Our hand crafted lightweight minimalist interior is trimmed in the finest materials, whilst aluminium is used for all the vehicle controls to make the 993R feel very special.

Bespoke Luggage Compartment

No Paul Stephens Autoart car is complete without its signature luggage compartment. Our remotely operated aluminium bonnet reveals a beautifully trimmed space for personal belongings and additional items in the lower storage area.

3.8 Litre Engine

Producing 360 BHP

At 8500 RPM

The 993R 3.8-litre engine, features a 997 GT3 crankshaft, RSR pistons, and camshafts machined to Paul Stephens’ own design. Peak power of 330 bhp is achieved at 7,400 rpm as opposed to the original 272 bhp at 6,100 rpm. In this configuration, the team were focusing on daily driveability with good torque and power. For those wanting more power, a 360 bhp version is also available with a visceral 8,500 rpm redline.
