And it definitely looks like you have more drop then me...since I need an alignment anyway, I think I'll start with that instead of wasting my time with other stuff...

Let me know how that comes out. I'm debating CC plates. Would be nice if they could adjust enough to where I don't need them. I think you got the same Dub springs I got.

If I had to guess on your vib.. It's probably the same vibration I had when I drove my car off the lot. Pull the driveshaft down and put it back up. Vibration gone. Started at 60mph. Was strongest around 65. Faded away after that.

What do you mean pull the driveshaft down and put it back up? Uninstall and reinstall?

Subbing, I'm battling a vib at 75-up right now. I just had my tires re-balanced and it's not that.

I just put on non-adjustable LCA's so if it ends up being pinion angle then I'm going with a UCA.

Im out of town for a bit but when I get back, this is my first project after unpacking

That's what they did at the dealership the 4th time I took it in for vibration. Actually you may not even need to take it down. Just unbolt from the pinion and turn it a 1/4 turn. I've had this issue on a couple of my stangs and that always seems to fix it. If it makes it worse turn it the other way a half turn. I usually end up replacing the factory shaft for something aftermarket and the problem goes away completely. But considering these run nearly $1k I'm on hold.

I might try taking mine to a driveshaft shop here in town and see if he an re-balance my stocker.

Or see how much he will get me for a custom one-piece

I got back late last night and installed the new 19" wheels and pirelli neros tonight when I got home from work. I drove around for about an hour tonight and didnt have any vibration whatsoever. Of course, I was driving around like an idiot too because I've been trapped on a cruise ship for over a week and felt the need for speed. I'll drive more normally tomorrow and try harder to duplicate it, but so far, looks like an unbalanced wheel or something was the cause.

I'm starting to think mine is tire related too. Glad you seem to have gotten yours straightened out.

I had a very mild bent strut that caused vibrations between 60-80, ended up dropping 3k on suspension to replace it all, and it went away
