Just measured it, M18 x 2.5mm Pitch.
You'll need a 15.5mm drill to tap it.

I would find the tap for you as well, but I'm not sure if your doing a blind hole or through hole.
For the price of the material, and the drill and tap you will only use once, I'd find a local metric machine shop . I'd get it done for you but we are primarily imperial due to having American customers, we do have some metric taps, but nothing "exotic".
And Cal's big dirty Bora lol
wicked "see through and slow pic" car is real smart, really like it!!
dont think you will get that jet engine noise you want. I have had mine on since august i think same as what your getting turbo back with 100 cell has a nice note but not agressive i dont think although havent been outside to hear. Maybe louder with a remap though as mine is standard. Love the wheels by the way had thought about spraying mine yellow or something lol but shall wait and see. (not the lambo as they shall be off).
liking the tow hoop aswell i want.please
