Morning,
Someone may need to confirm but I think that Facelift FR Bumpers fit all other Facelift Leons
Be careful for parking sensor and headlight washer holes that your car may not have currently
I'm pretty sure that to put a Pre facelift front FR bumper on you would need new headlights and grill so make sure you find a Facelift version.
Rear bumpers are the same for Pre and facelift I think...
I'm no pro so make sure someone else confirms this or go into a full search session to find someone else who has done this lol
This may not
help you now but someone who does know may just be able to say yes or no to what i've said haha
Cheers
