Unsprung weight
Exactly.... see how suspension tuning is just about the springs or any other single part? Mike was probably running those pressures all along, but the additional weight of the 12-bolt and TA changed the dynamics of the car and what was ok before is now likely too much. No tire compliance, and a lot of weight.... kind of like driving a steamroller.

I dropped the pressure to 30lbs all around last night and drove around a little. Ride is better, but now they're rubbing more, since the sidewalls are a little "fatter".
Sam, I tried to call you yesterday, but I missed you. Do you sell 10mm spacers? I saw H&R listed on your site as a vendor, so I'm assuming you can get them. I know you don't list everything you sell on your site. My only concern with spacers is the tires are pretty much dead even with the fender skin now. If I move them out any more, I'm likely to bounce the fenders off the tires.
I know, I know. I'm running tires that are bigger than the engineers ever designed these cars to fit. If I can't make it work, I'll start saving up for 17x9.5's and get drag radials mounted on the 17x11's.

You can get a thin pair of spacers down at autozone. Just use one and adjust the bar to compensate. Even though the tires may look like there sticking out too far that will only matter in dips. Under cornering the outside tire will get pulled in as the car body rotates and it should miss touching the fender lip. Ride height also plays a huge factor in this.
Here is some info on lightweight rearends if you haven't already bought one.
