The wheel housings, side sills as well as the front- and rear bumper were remodeled and improved at the so-called „dp11 Red Evolution“ body which is coated in Porsche guards red (80K). The windows of the lightweight doors consist of hardened plexiglass. Even the water drains were removed. All body parts are made of carbon or glass fiber reinforced plastic (GFRP).

The vehicle inhabits a H&R suspension coil over system and adjustable dp-stabilizers type RSR. The front axle strut bearings as well as the turbo rear axle guides are Unibal-mounted and the front axle PU guide sockets are supplied by Superpro. The welded strut brace as well as the brake system of a 911-3.3-Turbo deserve special mention. The wheel-tire-combination with Fuchs rims in the dimensions 9 x 15 are assembled with Michelin semi slicks TB in 225/55-15 on the front axle and in 13 x 15 with 335/35-15 on the rear axle.

The 3.500 cm³ (213,5831 cubic inch) capacity engine is equipped with a mechanical fuel injection system with individual throttle valves, a dual ignition system as well as 911-RSR camshafts. The results are mighty 374 hp (275 kW). Edelweiß Motorsport coordinated the mechanical fuel injection pump on a dynamometer. The transmission type 915 with limited slip differential, steel synchroniser rings and oil cooling received an elevated shifter and shortened shift travels.

Even the interior endured an extensive upgrade. While enjoying the Lollipop race seats in the 935 style, the driver is looking through a 350-mm Momo steering wheel on a carbon dash board with carbon knee rails. The coated tin in the interior is furnished with a 964 RS style light-weight velor carpet. Ultimate protection for the passenger is provided by a welded, red coated safety cell as well as 4-point professional harness by Schroth.

Also the bonded windshield type 993, a light motorsport battery, a custom-made racing wiring harness and a carbon clubsport tank with 80 liters capacity are worthy special attention. The result of 940 kg (2072 lb) unladen weight (without fuel) is remarkable!

The denoted price is negotiable.
