Pre-LCI and LCI diffuser compatibility

I've been making my eyes bleed looking at photos of both pre-LCI and LCI M Sport diffusers trying to figure out why they're listed as incompatible between them. Is there actually something physically different between them that would not allow you to use them interchangeably? The G30 LCI doesn't seem to be listed on realoem yet so I can't confirm there if the part numbers are the same

Anyone have a definite answer on this?

Not sure if this is definitive, but the aftermarket M Performance Style diffuser I have is listed as compatible with 2017-2023 cars. It would make sense that any Pre-LCI diffuser would fit an LCI and vice versa.

Thanks, that's what I was seeing on some products. I may just buy a cheap one and see before pulling the trigger on the Karbel one I'm looking at. I asked them and didn't get a real answer either

I assume you are looking at this one since it is the only diffuser they have listed for the G30. It is listed as 2020 on and references LCI. The 2020 is not an LCI, so if it fits the 2020, it will fit the 2018-2019 as it is the exact same bumper, slots and tabs. On a side note, I did look over the RW Carbon offerings, and they have specific diffusers for 2017-2020 and 2021-2023 cars listed that do not cross over. So maybe there is some type of difference? I know the diffuser I have has been installed successfully across all model years, so I don't know what the difference could be?

Maybe hit up RW. They are very responsive.

Yeah I was thinking because Karbels front end G30 stuff is LCI specific, they just kept that phrasing through the other listings. The spoiler is listed as 2017 on though so I second guessed that logic. I'll reach out to RW, I'd already been bugging them about other stuff the I'd ordered from them lol

LOL! Yeah, I bought a few bits from RW. I am probably tagged as a pain in the ass in their system.
