(from RDSport Press
Release) Over 25 years of experience in building the most
performing motors for BMW are the legacy that RDSport infused in its
latest M3 program.
RDSportís range of performance parts is as exclusive as it gets, and
will allow you to custom build your M3 to match your preferred
All of RDSportís products are engineered to work together, so you
donít have to worry about compatibility or fitting. We engineer and
design it all in-house; therefore we can stand behind our products
100%. If that is not enough, we have many of our products tested by
the German T‹V, so you can rest assured that we have done our
homework beforehand, and you are getting a product that is approved
for use on the M3 by the same authority that certifies the car in
the first place.
It has always been BMW's trademark to produce the best, most
sophisticated, naturally aspirated motors in the world, and these
power plants have been winning Engine of the Year awards for the
At RDSport we have always believed that our engines should match the
configuration of the BMW motor that we set out to modify, as this is
the only way to retain the true character of the car, and provide a
product that matches the reliability of the original motor.
The RS46 is truly the motor that BMW should have installed in the M3
in the first place: massive torque, blistering acceleration, and
performance that puts many sports cars to shame.
Its engine internals are made from the highest quality materials,
and could easily withstand the rigors of Formula One. In fact, if
you were to compare the piston of an RS46 to that of an F1 motor of
only a few seasons past, you would notice how close the two really
New engine internals
include larger, forged, light-weight, aluminum pistons, forged,
billet connecting rods and new billet crankshaft with a longer
stroke. All of these parts equate to a larger displacement 4.6 liter
motor, up from the factory 4.0 liter.
Also included in the build is a complete exhaust including; race,
tubular headers with F1-style merge collectors, metal-matrix, sport,
catalytic converters, X-Flow downpipe and sport silencers all built
from stainless steel. Options for the motor include carbon air box,
larger-displacement, carbon plenum chamber, power pulley,
lightweight clutch and flywheel. The result is an amazing 524 bhp
and an increase of 115 ft-lbs of torque over stock!
The RDSport front bumper is available in Stradale (Street - shown)
or Corsa (Race) versions. Each is a complete bumper replacement made
of carbon/Kevlar and contains larger ducting for brake and engine
The RDSport rear bumper features a carbon fiber/meshed diffuser
section that allows for more weight saving and gives the aggressive
rear that the RS46 deserves. The unit is a full replacement fascia
of the original. Again to match the front and save weight the piece
is constructed entirely carbon/Kevlar mat, which is extremely light
and impact resistant. RDSport aero parts can also be fitted with the
factory PDC sensors.
Also available are trunk and roof spoilers to smooth the airflow
leaving the vehicle and aid in stability.
The RS46 is equipped with the RDSport Chassis kit consisting of
specially valved Bilstein shocks and RDSport Springs. The set up
leaves the vehicle with a 30 mm drop in the front and 25 mm lower in
the rear. The shocks and springs are designed to work together
beautifully and provide an extremely stable ride without any
harshness. This optimized set-up was made available only after
thousands of testing and development miles.
The RDSport RS Brake
System consists of 6-piston, aluminum monoblock calipers on the
front and 4-piston monoblock calipers in the rear. Customers have
the option of ordering either cross-drilled or slotted rotors.
The RS2 Forged is the
most classic and recognizable Racing Dynamics wheel design and it
represents the latest iteration of a line of wheels that started
back in 1986 with the first HSM wheel.
The center flange is machined out of a heat-treated 6061-T6 forging.
Each one goes through 6 different machining operations totaling no
less than 8 hours on our CNC equipment. The result is a stunning
sculpture of incredible strength and lightness, with design details
that are unique to this product and cannot be found on any other
forged wheel in the market today. Due to the custom build of each
wheel there is an endless selection of color options and finishes.
offers the RC8 Forged Monobloc wheel that offers the ultimate in
light weight performance. RDSport recommends Pirelli tires.
Several interior options are available from a simple shift knob or
pedal set to a complete Alcantara interior conversion.
