I've wanted to swap out the body color slat grill with the Aero grill and it looks like I may have missed the boat. https://www.detroittuned.com/mini-gen-1-aero-grilles/ I ordered a knock off from Amazon, but I believe the honeycomb holes are larger than the factory version. https://www.amazon.com/gp/product/B0042FS18M/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&psc=1
I thought it was the bigger upper grille that was discontinued. I've seen couple of lower grills on FB for sale. Sent from my iPhone using Tapatalk Pro
Not sure if the honeycomb is larger but you will have to pant the front hood bracing under the grill black.
Did you mean eeuroparts.com? No luck on that site either. I'll report back in a couple of weeks when I get it installed.
I may have jumped the gun and missed this: https://www.waymotorworks.com/aero-grill-kit-r50-r52-r53.html
The aero grill is sold out at the dealership but you can find them at other places if you look hard enough.
