Looking for a verification that my Pinion angle is good/acceptable. As the title says, I’ve got a Mk4, with a Gen3 Coyote mated with a TKX, three 1/4” spacers between the transmission and the FFR trans mount and an IRS. Below are my angle measurements, which I believe are well within the range they should be. I have a digital angle finder that I zeroed on the DS 4” frame tube and made the other measurements with.
Transmission is: -1-3
Drive shaft is: 0.0 (level)
IRS is: +0.6

My beer math says that’s within 2 degrees, so acceptable.

Any differing opinions? I know there is a lot of guidance out there in this site, which I’ve read and re-read.
Thanks,
-Bryan

My 20th Anniversary Roadster with the same setup (TKO vs TKX, same difference) measured nearly the with a 3/4-inch spacer under transmission mount. 6,000+ miles later when I sold it, still working perfectly. You're good.
