GKTECH’s Conversion Hubs make it simple to upgrade your setup and open the door to a huge selection of performance and aftermarket wheels. Designed as a complete bolt-on solution, these hubs allow you to remove your OEM 5x100 hubs and install the new 5x114.3 / 5x100 units with no custom fabrication required.

Features:

• Direct Bolt-On Upgrade: Works with both 5x100 and 5x114.3 configurations.
• Durable Construction: Heat-treated structural steel body and flange for maximum strength.
• High-Quality Hardware: Pre-installed Grade 10.9 wheel studs using OEM ID (14.3mm).
  
• OEM Integration: Maintains factory hub offsets and ABS functionality.
• Pre-Assembled: Includes OEM-quality bearings, seals, and SHELL grease for easy installation.
• Hub Bore: Factory 56.1

When converting your FR-S / GR86 / BRZ to 5x114.3 using GKTECH conversion hubs, the OEM rotors will no longer fit due to the increase in hub size—unless you are running an OEM Brembo setup.

GKTECH partnered with HFM.Parts to develop these custom rotors specifically for the 5x114.3 conversion. Beyond simply serving as a replacement, the rotors feature curved indentations on the surface to enhance dust and debris clearance while improving ventilation. The black-coated rotor center not only protects against corrosion but also completes the rotor’s performance-oriented aesthetic.

Note: Can only be used to replace the OEM GTS 293x24mm rotors.

Rotor Fitment Notes:

• USDM Non Brembo Brakes
  • Rear: Re-drill your existing rotors to the 5x114.3 pattern, or DBA 42663S-10
• Non-USDM Delivered Vehicle: These front hubs will not work with the 277 x 24mm front rotor setup. These hubs can only work with the Brembo and (USDM) 292 x 24mm rotor variants. 
• Aftermarket Big Brake Kit front rotors must have a minimum inside diameter of 140mm to clear the conversion hubs (allowing for 1.0mm clearance)
