The TuffAnt Alloy ET27's fit all model D5's up to and including MY20. The below information pertains only to the TuffAnt Steelies (offset ET27).
If you have an MY19 model or later SD6 (HiPo) version you will not be able to fit TuffAnt Steelies without modification. The good news is that at this point the new Generation 2 Steel wheel will fit every other Discovery 5.
As always, if you are not sure, please drop us a line or give us a call during business hours and we would love to help you out. Checkout the Fitment table also for detailed information about what wheels will and wont fit.
