Hello from France,
it's a 1/8 scale that we call "classic car".
In US, you call it maybee Pan Car.
No suspension in the rear, adjustable chassis stifness, adjustable oscillation in the front, toe in and camber adjustable both rear and front.
It's an awesome categorie because it's so reliable.
You buy the chassis, you buy an engine, not a big one (RB S7C, JP Basic Line, OS VzR...) and you play a year without anyhing to change, only tyres...
Front tyres are in 45° shore, and rear 34/37°, very long lifespan..
The first 1/8 onroad category in RC history.
I love it.
