The transmission has now been in for ~4,000 miles, and everything has been running very well.
I removed the optima lightweight battery in favor of an OEM sized unit, which has been so much more reliable and worth the added weight.
Pic of my super scientific measuring method. I had to replace the negative terminal because it had become fused to the battery. Much better now.
I also had a fun night at the local test and tune. Unfortunately, a combination of street tires and my bad driving led me to another round of 13.XX passes, but no broken transmissions this time, hooray!
From the racetrack to singletrack- I also took the GTI on a short camping trip, and it was awesome! What a practical racecar

.
Unfortunately, my recently installed dogbone mount suffered a failure after ~1800 miles. I'll chalk this one up to launches on the drag strip and weakening from the transmission fluid leakage.
Verkline was awesome and sent a replacement set out. I haven't installed them yet, as it requires removal of the subframe again. Fun times!
At least I was able to install a DBV2 inlet pipe, which flows noticeably more than the APR piece that was previously fitted. Looks nice in the engine bay as well!
As temperatures in AZ rise north of 110 degrees I dont plan on doing much street driving, but will continue working on small projects around the car!
