GRCR Racing Classes

Super Tourers


TCR Rules with retro bodies!

Before TCR there were Super Tourers - the original FWD Touring Cars!
So grab a pre-2000 BTCC style body and fit it to your TCR chassis and come racing in Super Tourers!


Any front-wheel drive chassis is allowed. Chassis must have independent suspension on all four wheels. Each driven wheel must have a flexible joint, eg: dog bone/s or universal joint/s in its driveshaft. Drive train and suspension design is free from restriction. Flat Pan (1/12th and 1/10th Track Style) chassis are not allowed.


The Chassis must not be shaped to gain an aerodynamic advantage. In principle the underside of the chassis must be flat and parallel to the ground along the entire length of the body-shell. Aerodynamic shaped parts (splitters/diffusers/tunnels/etc) may not be fitted to the chassis.

Motor & ESC Combo

  • Hobbywing XR10 Justock 13.5 combo.

  • Motor: Justock 3650 G2.1 13.5 (legacy G2 variant also legal)

  • ESC: Xerun XR10 Justock G3 (legacy non-G3 variant also legal)

Body Shell

Eligible bodies are reasonable scale representations of any pre-2000 Sedan/Hatchback/Wagon that competed in 2L Super Touring Championships - BTCC, JTCC, ASTC etc. This is a fun category so we encourage scale accuracy of bodies and paintwork!

  • No solid flat disc faced rims.

  • Tyres are rubber only, open compound, open inserts.
