Got the new tires put on yesterday and took the car in for an alignment today. The asian dude who speaks bad English came out and showed me this printout and my camber is -2.3* and -2.1*, he said it'd be an extra $40 to have them go under the hood and adjust from the top , so I said don't bother with that.. -2 degrees seems pretty bad, I believe it was -1.5 when I had the car aligned with the 275s, and it was lower than this.

The other measurements are:

Caster: 4.4* 4.5*
Toe: .12* .21*

Don't really know the science of caster/toe, but the car doesn't pull in any direction and the steering wheel is straight (it wasn't with the other tires), but I'm still worried about some loss of useful tire from the camber. Is it fine how it is..or.......

I have 4 bolt MM CC plates
H&R Super springs / no isos
Bilstein HD struts

There is still some room to pull the camber out on the MM CC plates, trying to find some information on how to measure it yourself.

 

There is a tool that MM sells to adjust camber yourself. Mine was at -1.8* a week after I lowered it and the stock plates are maxed. It caused noticeable wear to the inner edge of the tires and I just had to pay Tire Kingdom to "Flip" the tires so the fresh edge in now on the inside.

Mine has also settled more since then so I'm probably close to your specs now. If you still have room, I'd recommend you get some of that camber dialed out so your tires last longer.
