Wow thats some strong carbon fiber right there!

Really? The 4 bolt one actually had two machined socket head cap screws that acted as alignment dowels on the under side of the flange and then the 4 bolts you could see. That one was bought late last year from modern driveline.The 4 bolt flange is likely a early production piece. All the qa1 carbon ds I've had and seen all had the 6 bolt. U joint failure is a real thing as I have suffered that at one point. It's Def something you want to keep an eye on. With a one piece ds, the angle on each side needs to be equal and minimal. If not, a certain level of vibration occurs as the shaft or pinion yoke oscillates in speed as one of the yoke/flange angles increase. The u joints usually take a beating.
Interesting on the 4bolt flange. I'm sure it is plenty strong. Just be sure to split the angle differences equally on both ends if possible. You can also shim the rear cradle downward if needed.Really?

As far as I understand the only way to adjust pinion angle on these cars would be to shim the trans up or down. Presently it has less than 1* of difference between the pinion and the back of the trans. Same as before, and zero vibration.
Watching it like a hawk. All the plugs looked great after this incident. Once I put everything back together it fired right up and drove like it never happened. Iām thinking I could have possibly over-serviced the cooling system when I first fired the car. Looked like it puked maybe 1/4-1/2 gallon of fluid, I only added a cup full back to top it off. I would think it would have done the same thing during any of the previous pulls. Very odd.Good power. Keep an eye on that coolant issue. If it's hard to start, have more water vapor coming from one exhaust pipe or have a odd looking spark plug or two you got a head lifting. I've been through it a bunch.
