Hamann HM3 EVO Edition M3 Convertible
You've got to question the logic of a 180-mph convertible. Why not simply remove the roof of a Cessna Turbo Skylane, a sleek, commuter aircraft that's almost as fast. Hamann GmbH doesn't tune planes, however. It tunes automobiles, primarily ones built by BMW. Although this convertible 2004 M3 has more than enough power to fly, Hamann's aerodynamic program ensures it stays well grounded. Hamann's carbon-fiber body kit is comprised of a Competition front spoiler, side skirts and adjustable rear wing. The aluminum hood was fabricated by Radenergie and features dual vents for additional cooling. Radenergie carbon-fiber side gills and Hamann brake cooling ducts ensure properly directed ventilation. The lighting system was modified with Hamann's new illuminated rings and utilizes "cold cathode" technology like that found in computer scanners.
The chassis sits nearly 2-in. lower via Radenergie's autobahn-spec coilover suspension, complemented with Hamann swaybars measuring 29mm in front and 25mm aft. Brakes are massive 4-piston Brembo units sized at 355mm fore and 320mm aft. Hamann running gear consists of its PG3 EVO Edition 3-piece wheels measuring 8.5x19 in front and 10x19 out back, shod with Pirelli P Zero Rossos sized at 245/35ZR-19 and 275/30ZR-19.
The engine was modified with Hamann's Sport EVO carbon-fiber airbox and Stage III computer upgrade. Hamann's Sport EVO stainless-steel exhaust manifold augments its full stainless-steel exhaust, including EVO Racing catalytic converters. The interior was fitted with Hamann's pedal set and EVO Edition foot rest with a Hamann shift knob for the SMG shifter.
APR 911 Twin Turbo
APR states that, with no other changes, its EMCS electronic enhancement will increase the output of the 911 Twin Turbo by more than 80 hp. It's not exactly free, but that is just the first hit. Your chain of addiction is liable to include APR's free-flowing, all stainless-steel exhaust, adjustable-height coilover suspension with a five-position adjustable front anti-roll bar and spherical-bearing end links, all tuned by Champion Motorsport, and Champion's 18-in., forged, magnesium wheels. Mix this in your bathroom sink with a set of Michelin Pilot Sport tires, and you have the car I drove at Michelin's Laurens Proving Grounds. The pavement was mostly dry, but cool everywhere and damp in patches. The car's power and 3600-lb curb weight meant sideways was the only dish on the menu, but dessert was a measured 12.4-sec. quarter mile with-119 mph trap speed. First-gear acceleration peaked at 1.04g on one run. APR's exhaust sounded just right, uncorking the German baritone. Since then, the car has received a 14-in. front and rear Brembo brake upgrade and larger K-24 turbos instead of the K-16s it came with. If this sounds interesting, go call APR.
