This allows the piston to 'deform' and better absorb combustion forces before a catastrophic failure. These pistons will be softer and more ductile than a piston with more silicon content. The 2618 is a low silicon and high expansion material with better tolerances and higher resistance to detonation. This is a material usually reserved for racing and other 'heavy duty' applications. Mahle uses their high-performance 2618 alloy for their S54 pistons.

This piston set matches all of the factory piston specs for bore and compression. Forged pistons are inherently a stronger material and more robust in these extreme conditions. These types of combustion forces can make it brittle or even deform the piston shape or size. The strength of cast parts is susceptible to heat, detonation/knock, and other timing or fuel issues. But increase the performance and the cast aluminum becomes a weak link at some point. Factory BMW pistons are cast aluminum, which is fine for the intended power output and durability. The E46 3 Series Coupe model is a car manufactured by BMW, sold new from year 2003 until 2006, and available after that as a used car.Mahle Motorsports S54 pistons are forged for strength, light weight, and low drag to be a more specialized application than stock BMW pistons. For stopping power, the E46 3 Series Coupe M3 braking system includes Vented Discs at the front and Vented Discs at the rear.

Stock tire sizes are 225 / 45 on 18 inch rims at the front, and 255 / 40 on 18 inch rims at the rear.

anti-roll bar front suspension and Multilink. On the topic of chassis details responsible for road holding, handling behavior and ride comfort, the E46 3 Series Coupe has Independent. The power is transmitted to the road by the rear wheel drive (RWD) with a 6 speed Manual gearbox. This engine produces a maximum power of 343 PS (338 bhp - 252 kW) at 7900 rpm and a maximum torque of 365 Nm (269 lb.ft) at 4900 rpm. With a fuel consumption of 11.9 litres/100km - 24 mpg UK - 20 mpg US (Average), 0 to 100 km/h (62mph) in 5.2 seconds, a maximum top speed of 155 mph (250 km/h), a curb weight of 3241 lbs (1470 kgs), the E46 3 Series Coupe M3 has a naturally-aspirated Inline 6 cylinder engine, Petrol motor, with the engine code 32 6S 4.
