TRAXXAS GT4 TEC 2.0 +1mm 8mm Aluminium Wheel Hex with Brake Disk - GT010D+1MM by GPM  [GT010D+1MM]

8mm aluminium +1mm hex with integrated brake disk

The GT010D+1MM hex set is an aluminium +1mm wheel hex upgrade that ships with brake disks for TRAXXAS GT4 TEC 2.0 4WD cars. It extends wheeltrack and improves the wheel mounting interface to produce steadier turn-in and more repeatable chassis behaviour during setup and track work.

Included items and reference: brake disk - 2 pcs, 2x10 pin - 2 pcs, Manual number: 8356. The hex plays the mechanical role of joining wheel to axle and adds a machined swirl ring for a refined visual finish.

Design notes: the outer ring has a swirl engraving for a contemporary look and the hub body is 8mm thick rather than the usual 7mm, increasing lateral track and altering roll couple and stability. The larger overall diameter is not compatible with the stock brake caliper so measure clearances before installation.

Installation advice: these hexes change offset and track width, so small handling shifts are normal; confirm axle pin retention, check thread engagement, inspect wheel runout after fitting, and use the offset as a tuning variable to improve chassis balance.
