TLR® engineering has turned the drastically improved 22™ 4.0 buggy kit forwards and backwards. The result is a dominant 17.5-class SPEC racer that’s under ROAR weight, right out of the box with the options and tunability you need.
Features
The 17.5 buggy spec-class is the biggest class in electric off-road racing and perhaps all of RC today. A fully optimized buggy with a specific focus on stock racing is required to be competitive at the top end of the category, and the TLR ®22™ 4.0 SPEC-Racer delivers such a buggy, right out of the box.
The 22 4.0 SPEC-Racer kit takes the drastic improvements made in the on-track performance of the new 22 4.0 and maximized the drivetrain for spec racing. Sounds simple, right? NO! That’s because our goal was to turn the weight loss requirement into a performance gain opportunity. For starters, the car has shed weight by replacing carefully chosen stock 22 4.0 parts. The transmission boast the biggest gains where a Direct Drive System with a shortened top shaft, an aluminum diff with composite outdrives and aluminum CVA driveshafts with lightened steel axles has minimized overall weight and rotating mass.
In true TLR fashion, handling was a particular focus. A laydown transmission moves the motor forward by 20mm+ to a central motor location and provides two diff heights—standard 3.0mm and +3.5mm for carpet and Astroturf. This creates a chassis that drives much flatter, more consistent and corners quicker, especially on throttle which is critical for spec racing.
All told, the 22 4.0 SPEC-Racer weighs in under the ROAR minimum weight of 1499g, with no modification. But it’s the moment you hit the track when the advantages becomes clear. Front to back, the 22 4.0 SPEC-Racer is more capable of competing for wins right out of the box than any other stock 1/10 2WD buggy in its class.
Weighs in Under 1499g
There’s no need for titanium hardware to make minimum ROAR weight. The 22 4.0 SPEC-Racer, when built with the kit hardware and the recommended Orion® and Spektrum™ electronics weighs under 1499g when ready to hit the track.
Laydown Configuration
The 3-gear laydown transmission moves the motor forward by 20mm+ to a central motor location, providing a chassis that drives much flatter, more consistent and corners quicker—a crucial advantage in the 17.5 spec buggy race class.
Lightweight Drivetrain
To maximize the top speed and performance of a stock motor, the drive train has been lightened with a Direct Drive System including a shortened top shaft, narrower idler and diff gears, aluminum diff hubs with composite outdrives and aluminum CVA driveshafts.
Stiffezel Suspension Components
The higher glass content of Stiffezel molded composite is strategically used on suspension components to provide more consistent and stable driving. This includes the front and r
