I ordered it from RHD Japan. Took about 6 weeks to arrive. No issues. They were good about keeping you posted as to the status of the order.

Just got mines in from RHD Japan as well. Order date was the 13th, arrived today on the 20th. They apparently had the FRP version stocked.
RHD Japan is quite good on keeping you updated through their website like the above member just said.
There's various pics available already but it doesn't hurt to put more.

I ordered my carbon fiber one on the 18th. Curious to see when I get it. Just need it before April 3rd...

Depends on where you ordered from. I bought mine from japanparts and after checking my order status, I was given an estimated time of 2 months. It's been a month since I ordered. I think you should be ok and will receive yours before April for sure.

Ordered from RHDJapan. Says stock was confirmed

For anyone interested I have one brand new in box for sale with the 3M VHB tape. In case you don't want to wait for it to ship from Japan.

Damn... I should have ordered from here and not slow azzz japanparts :mad:

If it makes you feel better it still says stock confirmed

Unfortunately I already ordered mine from Japanparts, but had I known it was gonna take over 2 months to get it delivered, I would have ordered from RHD :shakes head:

Just ordered mine!
Is that the strongest tape to use?
And how hard was the install? (Any issues with placing it and it sticking incorrectly?)

Install is cake, The only advice I can really give is place the double sided tape lower then the lip and not so close to the edge so it's not visible when you attach the diffuser to the car.

Just how lgarcia posted that pic of the 3M placements righ?
