VTT ultimate G8X ultimate rear brake conversion kit
VTT is happy to announce its new rear brake conversion kits for the G8X platforms. This is the FIRST and only kit currently on the market that will allow 17″ wheels and tires to be run on the rear. This kit replaces your rear brake rotors and calipers to fit 17″ wheels. It includes GENUINE BMW calipers that RETAIN full parking brake function. This means no downside, 17″ wheel fitment, parking brake functionality, no loss of braking power, 26.4LBS unsprung/rotating weight removed.
The kit consists of:
- 2 Wilwood Spec 37 HD rotors
- 2 Genuine BMW Calipers
- New HD brake pads
- All hardware required for the swap, including brackets. bolts, and adapter fittings
These kits will bolt directly onto the chassis specified, BUT many different 17” wheels in many different offsets exist, we cannot guarantee this will clear your wheel/tire combo without some clearance.
Please note – You must remove the rear brake dust shield. This is 100% reversible
