Stock is as the vehicle ships. Calculated is worked from the stock figures on this page rather than stored beside them, so the two cannot drift apart. Derived is worked out from gear tooth counts the maker publishes rather than printed as a ratio; the notes below say how. Not applicable means the vehicle does not come with it, like the motor on a roller or the tires on a race kit, or does not have one, like a KV rating on a brushed motor. Not published means it exists but no source we could find prints it.
Gearing parts

| Pinion | 15T | 48P | Not recorded | 148015P |
| Spur | 75T | 48P | Not applicable | 230108 |
Tooth counts are the ones in the specifications above. Pitch is given as metric module (Mod 1, Mod 0.8) or diametral pitch (32P, 48P). They are different standards and are not interchangeable, even where the numbers look close. Bore is the pinion’s hole, listed separately from the motor shaft.
How these numbers were settled
Front-motor front-wheel drive touring car that converts to mid- or rear-motor rear drive, with a 15T 48P pinion driving a 75T 48P spur that forms the ball differential, 5.00 overall.
- The manual's parts pages list one 15T pinion (148015P, p. 7) and the 75T differential spur (230108, p. 9), and the exploded view (p. 3) shows the spur carried on the differential with no reduction after it; MST prints no gear chart for this car, so the 5.00 is worked out from those tooth counts.
- The motor is the M54-35T brushed motor (brushed motors have no KV rating), and the XB60 brushed ESC is rated by MST for 2-3S LiPo or 5-9 NiMH cells.
- The stock tires are MST AD Realistic 50 degree (831001), whose outer diameter is not published.
- The manual rates the tray for a pack up to 140 x 48 x 27mm, or a shorty up to 96 x 47 x 25.5mm, and gives the wheelbase as 245, 251 or 257mm with 257mm marked.
- AMain hosts this manual under the 531811 number; its cover reads TCR RTR, FF drive.
