i contacted Z1 a couple of weeks ago as a follow up to my August visit. my contact guy was an RX7 owner... in the middle of zillions of high dollar modded Nissan iron. he was quite helpful and i am on the contact list should they, or when they, receive another TwinZ diffuser shipment. apparently there are differing widths... my FD is 55/56 in width for the mounting holes. the remaining diffuser they had in Aug was 59. i will post when and if the ship comes in IMO, they are pretty nice.

hmm never would have guessed. Lucky for me mine fit correctly! I took the bumper off to install it. I'm not sure you could install it properly with the bumper on. I still have mine installed on my bumper in my garage. Ill be out there today. If I remember I'll get a few pictures.
as readers of this thread know there seems to be issues w the fit of the TwinZ diffuser. i measured the width of the mounting area behind my rear wheels and came up with 55/56. since the only Nor Amer Dist was an hour and change from me i visited, with my tape measure. and found the only one they had was 59. no go. i received an email from them last week... they just received 23 diffusers. 4 Type 1 and the remainder Type 2. Great. i gave them a call, told them i was a buyer of a Type 1 and asked them to verify that they were the proper width for my car.
no, they really didn't want to open a box. "they all fit."
no, i really don't want any further contact w them.
i revisited my options and found i really liked the Amemiya Street Diffuser better. (of course we all have differing tastes) i am swapping in the diffuser so i can swap out the OE drag inducer for the Texas Mile... so it is mainly for function.
i was happy to see Shine makes the diffuser, even an uprated V 2 which has a bit better reinforcement where the mount goes from inside to outside. i am no stranger to Shine as when i swapped in my 295s in the rear i needed another 5/8 lip and they had a really nice unobtrusive eyebrow piece. i do recall that Shine recently moved and there may have been (understandably) some delays. my move from Wisconsin to Georgia was a challenge. i would hate to imagine moving a biz.
i am happy to say they had one in stock. i paid them Tuesday and received an email from Ken today that it is on the way.
here's the diffuser:

Installed the spoiler and diffuser last month, both fit really well. Mine didn't line up with the 2 plastic nut things either but I am not sure it was supposed to with the front strapped to the gas tank it hangs very snug.
I installed the diffuser as well and I'm getting the same "too wide" issue. the two square holes on either side to bolt to the body are not lining up with the mount on the diffuser.
I think they just removed the inserts from this car when they painted it. That rear most insert is really far to the outside of the car.

IMO, they are pretty nice.
