Milltek Sport exhaust

The Milltek Sport exhaust system gives the BMW 1 Series M Coupe a true sports car presence that’s worthy of the M nomenclature. Milltek’s exhaust is manufactured from anti-magnetic T304 aircraft-grade stainless steel and is available in a primary (eliminates the secondary catalytic converters) and secondary cat-back system. Both systems are manufactured out of 3-inch (73.2mm) mandrel-bent piping and finished in quad 80mm GT80 exhaust tips to add beauty and sound to the 1 Series. Company tests showed the reduced backpressure and optimized flow gained an average increase of 16 horsepower with the primary system and 5 horsepower with the secondary cat-back system.

CP-E Cast Stainless Downpipe

Custom Performance Engineering’s (cp-e) cast stainless downpipe for the BMW 3.0L N55 TwinPower turbo engine takes aftermarket performance parts to an entirely new level. Designed with a FARO Coordinate Measuring Machine (CMM), the cp-e 5-inch cast stainless downpipe flanges, sensor location and mounting points are within 0.010-inch of the stock locations. The bellmouth design minimizes backpressure and optimizes flow. The downpipe comes with a lifetime warranty and is available with or without a cp-e custom-designed high-flow catalytic converter. $759 (+ $200 for a Spun Metallic cat)

Vorshlag camber/caster

Vorshlag camber/caster plates are designed to fit the E90/E92/E93 M3 coupe and convertible, and the plates’ modular spring perch allows them to be used with coilover springs and virtually any strut type. The upper perch design allowed Vorshlag to add a sealed, double-row radial bearing to isolate the 19mm spherical bearing in the camber plate from radial turning loads of the strut shaft. In addition to being able to independently adjust camber and caster, they are designed for maximum suspension (bump) travel. Maximum camber adjustments of -2 to -3.5 degrees, depending on ride height, can be done easily with basic tools. Prices start at $439

Macht Schnell DCT Gauge Boss

In recent years BMWs have developed an annoying habit of going into limp mode whenever the fluid temperature goes beyond what BMW thinks is acceptable. A slight increase in horsepower, a weekend at the track, a spirited drive down Mulholland Dr. or a tour of Texas can sideline DCT-equipped M3s without warning. Unlike other critical fluids, the DCT gives the driver no indication of impending doom. The Macht Schnell DCT Gauge Boss dual 1/8-inch port design allows for the installation of temperature gauges to read DCT fluid temperatures both before and after the heat exchanger, giving you time to make the necessary adjustments to prevent the ECU from going into limp mode. $139

Dinan Stage 2 Performance Engine Software

Since 1979, Dinan has been developing and manufacturing high-performance parts for BMW. This long-term heritage lets them match the factory 4-year/50,000-mile warranty. So if you purchase Dinan Stage 2 performance engine software for the BMW 3.0L N55 turbo from one of their 130+ dealers (most of which are BMW dealerships) you will not have to fear your service appointments. The Stage 2 software utilizes full map rescaling, for improved drivability from idle to wide open throttle and everywhere in between, increased water pump speed and optimized fuel and boost calibrations. The result is a peak power increase to 355 at 5300 rpm and peak torque of 401 lb-ft at 3500 rpm. The Dinan software retains all BMW factory engine damage safeguards and offers lifetime upgrade and no additional charge. $1,999

AST 4100 Coilovers

AST 4100 coilovers for the BMW E82 1 Series/E90 3 Series (non-M) feature high-pressure nitrogen charged 12-way rebound adjustable monotube dampers with a load-bearing piston design. Durability and strength are the core principles behind AST dampers and that is why every steel body features a European KTL coating for total weather protection, and each is designed to withstand a 1-million cycle, 1,100-pound side load test. The AST 4100 system has been tuned for a comfortable yet aggressive ride that can transform easily from street to track use.
