DIY ZSpeed NISMO 370Z Aluminum Under Pan Diffuser

Looks good, interesting about the rubbing with the SC kit, I still want to order this since I am getting the Nismo front but wondering about the vibration.
The zip tie fix does not seem that big of a deal if it can hold the under tray properly.

Thanks

If you look here, the right circle shows where the IC piping was on the OEM piece. The left circle had to be zip tied with the OEM piece because of the oil lines. Everything is just really tight with the SC kit.

It has been on a week now and no issues. The vibration is only on a cold start. I got on it Wednesday and today and nothing flew out from under the car

UPDATE

I purchased a Spectre silicon coupler ($7.99) from Autozone and split it down the middle. I then cut that into 2 pieces. I zip tied the pieces to the IC piping and that eliminated the cold start vibration.

This picture shows where the direct contact was made with the IC piping. This contact occurred with the plastic under tray and the ZSpeed diffuser. Again, this is NOT a fitment problem with the ZSpeed part. It is a fitment problem with the supercharger IC piping.

This picture shows the coupler zip tied to the IC piping to eliminate the metal on metal contact and cured the cold start vibration.
