After 20+ years of road abuse my front fender liners and airducts were too broken to be usable. So I decided to have them changed with new genuine stuff plus close the bumper gap a bit. To do the latter one, I ordered some 3D printed bumper guides from trinitygraphicsnc.com that offer bigger adjustment and are beefier too. Also replaced the plastic cable ties with some new stainless steel ones.
Before:
Gap reduced from 15mm to 5mm, I think it’s just about as close it will get..
