Official Replica of the Iconic Quintessential
Sports Car

First released in 1982, the BMW E30 won plaudits from motoring magazines and fans of small, well-built European saloons around the world. The factory-upgraded M3 version, released in 1986, featured distinctive bulged wheel arches to accommodate larger tires and a wider track, spawning decades of lookalike custom cars.

On the racing circuit, the M3 came to dominate the late 1980s, securing the title of the most successful touring and  grand touring car to ever have participated in racing, including victories at the prestigious 24 Hours Nurburgring and the Spa 24 Hours and WRC Tour de Corse.
One-Piece Molded Chassis

The main chassis is formed from a single piece of reinforced plastic and features the drivetrain tunnel molded right down the middle, just like a real car. It's a step beyond any plastic tub chassis car available today.
 
Low Profile Layout Design

One of the ways we gave the RS4 Sport 3 the best possible handling was to make sure all the components fit as low as possible in the chassis. This gives the car an amazingly low center of gravity for enhanced cornering capabilities.
 
2S LiPo CAPABLE

The RS4 Sport 3 features a versatile electronic speed controller that can be used with modern lithium-polymer (LiPo) or nickel-metal hydride (NiMH) batteries. Please note a LiPo adapter plug is not included, your model shop will be able to provide one.
Fits a Wide Variety of Batteries

The RS4 Sport 3 chassis can fit lithium-polymer and nickel-cadmium packs of various sizes, including the extra-long 7-cell Ni-MH packs. Whatever your power requirements, it can hold it all! A thick hook-and-loop strap holds the pack securely in place, and a simple battery block screws into place to allow you to adjust the weight distribution forward or backward for extra steering or acceleration.
Full-Time Four-Wheel Drive

The RS4 Sport 3 features full-time four-wheel drive to give you the most control and precision on the road or track. All four wheels are driven by heavy duty gear differentials at the front and rear, just like a real car. The extra traction gives you increased acceleration and cornering control for maximum confidence and fun.
Sealed Shaft Drivetrain

The drivetrain of all the RS4 Sport 3 models features the motor mounted longitudinally in the molded chassis, next to the long driveshaft that goes down the center of the car. The entire drivetrain, including the central driveshaft and gear diffs, is completely sealed to prevent dirt, rocks and debris from damaging or binding the drivetrain. The driveshaft, diffs and axles spin on ball bearings to maximize drivetrain efficiency.
Bottom-Access Driveshaft

The central driveshaft that connects the front and rear differentials is easily accessed from underneath the chassis. This allows the drivetrain to be completely sealed to protect it from rocks and debris no matter where you may want to drive your car.
Option: Carbon Fiber Driveshaft Cover

You can easily replace the stock driveshaft cover on the bottom of the chassis with a carbon fiber cover that provides extra stiffness and extra-cool looks.
Easy Access Differentials

Getting to the differentials for quick adjustments is a matter of removing just 4 screws - this allows you to pop out the diff and change the grease, check the gears or just give it a general service.
4-Gear Metal Diffs

Bevel gear differentials at each end of the car transfer power from the driveshaft to the dogbones and axles that drive each wheel. The all-metal construction allows the drivetrain to withstand powerful brushless motors for easy upgrading in the future. Rubber-sealed ball bearings support the differentials and each diff can be tuned independently by changing the diff grease.

Option: Diff Spool

The optional diff spool removes all diff action for direct traction and braking action from your trigger finger straight to the wheels.
Double-Wishbone Fully Adjustable Suspension

The suspension of the RS4 Sport 3 uses the race-proven double-wishbone suspension design, similar to a full scale modern race car. You’ll be able to control the anti-squat and anti-dive of the front and rear arms using the standard pivot blocks, and the option parts allow you to adjust the sweep and toe angles. You'll also be able to easily change the roll center front and rear with the racing-style vertical ballstud mounting on both the inner and outer camber link mounts. Multiple shock mounting positions provide a full range of shock suspension angle adjustment to suit different road conditions.
MULTIPLE SHOCK POSITIONS
 
Option: Carbon Fiber Shock Towers

The option pair of carbon fiber shock towers not only look amazing, but also adds extra stiffness to the suspension for optimal performance. The carbon fiber material is extra-lightweight which lowers the center of gravity on the RS4 Sport 3 as well.
Oil-Filled Threaded Shocks

The RS4 Sport 3 is fitted with a set composite coilover-style oil-filled shocks, just like what you'd see on a real race car. The fully adjustable shocks are fully tunable to provide the optimum chassis performance on a wide variety of road surfaces. The ride height is quickly adjustable by using the threaded shock collars. Further tuning adjustments are also possible by changing the springs and shock oil weight.

Option: Anodized Aluminum Threaded Shocks

For optimum performance, you'll want a set of anodized aluminum threaded shocks that are machined to perfection. The full anodized aluminum threaded shock body, aluminum shock collar, aluminum top and bottom caps will allow you to make the most precise tuning adjustments.
Tough Front End Suspension

The RS4 Sport front end uses the strong C-hub style suspension seen on the latest RC touring cars, with a vertical ball stud camber mount that lets you change the front end roll center – which is a critical racing adjustment that allows the RS4 Sport 3 to be a step above other sport-level RC touring cars. The suspension arm also features multiple shock mounting holes for easy shock angle adjustment.
Option: PRECISION MACHINED ANODIZED ALUMINUM FRONT PIVOT BLOCK

The optional set of front precision machined anodized aluminum pivot blocks provide optimum rigidity and suspension performance. The extra rigidity and durability also provides for a more stable and consistent base setup for additional tuning options.
Tunable Rear Suspension

The rear hub is fitted with a vertical ball stud style adjustment that allows easy adjustment of the rear roll center. Moving the ball stud up or down with the optional spacers changes the traction characteristics of the rear end as the car goes through the turns. The suspension arm also features 3 different shock mounting holes for easy shock angle adjustment.
Option: PRECISION MACHINED ANODIZED ALUMINUM REAR PIVOT BLOCK

The optional set of rear precision machined anodized aluminum pivot blocks provide optimum rear end suspension rigidity and performance. The extra rigidity and durability also provides for a more stable and consistent base setup for additional tuning options.
Option: CVD Driveshafts

The optional all in one CVD drive shafts greatly increases the precision and efficiency of the entire driveline and steering for maximum driving performance.
Option: Adjustable Camber Link Turnbuckles

The option set of adjustable turnbuckles will allow you to quickly fine tune the camber setting of your RS4 Sport 3 for optimum performance.
Double Bellcrank Steering

The performance tested adjustable double bell crank system provides optimum steering precision at all speeds. A metal drag link plate connects the cranks for extra durability, the additional drag link mounting positions also allows for Ackermann angle adjustments.
Option: Anodized Aluminum Bellcrank Steering Set

For the ultimate steering performance, upgrade to the precision machined anodized aluminum bellcrank steering set. The included set of adjustable turnbuckles also allow you to change the front end toe angle to further fine tune your desired chassis steering performance.
Rugged Spring-Loaded Servo Saver

Fitted to the HPI SF10W waterproof servo is an adjustable multipiece servo saver, which protects the servo from crash damage. In the event of a crash or collision, the front wheels usually take a big portion of the blow and transmits the impact directly to the steering servo. The strong spring-loaded cam action of the servo saver is designed to absorb this force and protect the servo internals from the impact!
Aluminum Motor Mount

The cast aluminum cam-style motor mount holds the motor in place for a secure pinion/spur connection. Two screws hold the cam firmly in position on the mount, and cooling fins on the lateral support aid heat dissipation to keep the motor running as efficiently as possible.
Option: Machined Anodized Aluminum Motor Mount

The optional billet precision machined anodized aluminum motor mount will provide the most secure mount for your high powered competition motor.
 
Rear End Chassis Diffuser

The built in rear end chassis diffuser element smooths out the air flow underneath the chassis for maximum aero efficiency.
Rubber-Sealed Ball Bearings

The RS4 Sport 3 is fully fitted with a set of rubber-sealed ball bearings for maximum efficiency. The rubber seals keeps the dust away from the internals while the smooth precision bearings provides for optimum power delivery from the power source out into the driveline.
Rugged Front Bumper

To protect the front suspension, chassis and body from impacts big and small, an extra thick foam bumper is securely fastened to the front of the RS4 Sport 3.
