Our latest Micro RS4 release features an all-new Subaru Impreza WRX STI body, grippy rubber tires and is covered in the authentic PUMA racing livery of the factory-backed Subaru Global Rallycross (GRC)! Pro skateboarder and perennial X Games participant Bucky Lasek drives the #81 Subaru Impreza WRX STI sponsored by PUMA. Bucky has been skateboarding since the age of 12 and has been a car fanatic his entire life, earning several racing licenses on his way to getting on the Subaru PUMA Rallycross Team. 

Sverre Isachsen, Bucky's teammate, has taken 3 wins and 3 podiums with the Subaru PUMA Rallycross team in his 2 years of driving for the Subaru GRC team! The 43-year old Norwegian is in good company, as there are several Scandinavian drivers competing in Global Rallycross - but 'The Viking' has taken almost two dozen wins and 3 championships at the highest level of Rallycross in Europe, on top of 4 Norwegian titles!

The 4WD 1/18th scale Micro RS4 is the perfect car for burning laps inside and outside! It's packed with performance features like a high-powered motor for fast top speeds, direct drive for drivetrain efficiency, full-time 4WD, ball bearings for long runtime, high performance rubber tires and even coil-over shocks for excellent control!

The car is completely assembled and painted, and is equipped with a 2.4GHz radio system complete with radio batteries, electronic speed controller, 180-size motor, waterproof steering servo, 6-volt 1200mAh NiMH battery pack and charger. It's the perfect Ready To Run kit for anyone, young or old!


2.4Ghz Radio System


The Micro RS4 is super-easy to drive and get familiar with – all you have to do is install the batteries, plug it in and switch on the radio and car. It’s that easy! To drive the car, simply pick up the controller with your left hand, put your left index finger into the trigger area, and then put your right hand on the steering wheel – it’s as natural as driving a real car! Turn the wheel to go left and right, and gently pull on the trigger with your left index finger to go forwards. To stop the car, gently push away from you with your left index finger - hold it there to go into reverse. It takes only seconds to get used to this easy operation, and in no time at all you’ll be ripping off awesome GRC moves!


Both cars feature true-to-scale replica Method Race Wheels for an authentic scaled-down look, just like the real racing cars! Every wheel is wrapped with real rubber tires for fantastic performance on a variety of surfaces, from low-pile carpet to concrete and tarmac! The Method Race Wheels are exact replicas of the wheels used on the full-size Global RallyCross cars, and painted perfectly to match Bucky Lasek’s and Sverre Isachsen’s paint schemes!


Four Wheel Drive - Maximum traction on any surface

4WD System for Great Handling

The Micro RS4 features a smooth 4WD system to give you the best handling anywhere you drive. The belt drive runs down the length of the chassis from the direct-drive rear axle to the front differential for an efficient and elegant drive system that gives you the perfect amount of grip at the front and rear!.

Cantilever Front Shocks

Unique F1-style front shock absorbers provide a smooth steering response for great control. Independent front suspension is the ideal solution for a car this size, allowing your steering inputs to directly affect the direction and control of the car. You'll feel as if you're actually in the car, steering it around corners!



Easy Driving Anywhere

With its 4WD belt-drive system and grippy real rubber tires, the Micro RS4 is easy to drive on any smooth surface! Concrete, short carpet and even tarmac or asphalt are all ideal racing surfaces that were made for your car - you'll feel like a real racing driver with the Micro RS4!

Fun to Tune for Grip or Drift Driving

Tuning the car is simple with HPI option parts - not only can you change the body style and wheels for a whole new look, you can also change the tires and width of the car for different traction characteristics. If you want to get sideways, you can even install our #73419 drift-specific differentials for real Formula D style action!
