AT LAST! The GKTECH 5x114.3 conversion hubs are now available - a bolt on solution for converting your FR-S / BRZ or GR86 from 5x100 to 5x114.3 stud pattern.

It's common knowledge the 5x100 stud pattern leads to some less desirable wheel choices, a serious lack of availability, poor sizing and unable to run the classic favourites we've all grown to love over the years of modifying cars. With this conversion, we've made it possible to simply remove the old 5x100 hubs and install our 5x114.3 hubs.

- Heat treated structural steel body and flange
- Grade 10.9 studs pre installed using OEM ID of 14.3mm
- Compatible in both 5x100 and 5x114.3 configurations
- Compatible with OEM ABS systems
- OEM Hub offsets
- OEM quality bearings, seals and quality SHELL grease pre installed
- Optional HFM slotted front rotor for Non-Brembo models.
- Included 5x114.3 template for easy DIY rotor re-drilling

Both front and rear hubs come ready to install, with bearings and studs pre installed - making it easier than ever. For those using the non-Brembo calipers we're providing a ready to go front disc option, those using Brembo (PP) calipers simply re-drill the rotors to the desired 5x114.3 pattern using the template provided.

For Brembo brakes please check the inside of the rotor is flat for the hub to mount to, some rotors have an internal lip that is not compatible. Alternatively you could use aftermarket rotors that do not have this internal lip.

Installing the rear hubs couldn't be easier, using the template provided you can re-drill the OEM disc and install with all model calipers your car has installed. What makes it even better? It's completely reversible as the hubs are compatible in both 5x100 and 5x114.3 configurations!

Due to the rise and fall of other brands' conversion hubs, we have to be meticulous in testing and confident in the product before offering it to the public. To start with, choosing the right wheel bearing that is both affordable for the customer and meets the level of performance we require can be a little difficult. We made SURE these were ready for motorsport and daily driving needs, with testing including: Cyclical loading through a range of real world load cases including extreme high loads to simulate impacts, up to 800kg of load (equivalent to a total car weight of 3200kg). Over 900hrs of total loaded running time, 70+ days @ 12hrs a day whilst monitored for temperature and vibration throughout the testing and MORE!

FRS / GT86 / BRZ 5X114.3 CONVERSION HUB UPDATE!

NOTE: For those not willing to re-drill their OEM rear discs, there is a DBA rotor available off the shelf in 5x114.3 configuration - Part # DBA42663S-10

NOTE #2: If your vehicle is not a US delivered vehicle, note that our front hubs will NOT work with the 277 x 24mm front rotor setup. These hubs can only work with the Brembo and 292 x 24mm rotor variants.

NOTE #3: If you are running aftermarket brakes, your front rotor must have a minimum inside diameter of 140mm to clear the conversion hubs (allowing for 1.0mm clearance)
