I'll give that a try. I had to order the rears, so when they come in I'll give this one another go. I considered lowering the subframe but everything is so tight in the engine bay, I wasn't sure if it was a good idea. I think if I gain another inch or so, it should be good enough.
I know the feeling. As long as you don't pull the bolts out completely and you have something to support that side of the subframe you should be ok. There won't be subframe re-alignment issues when you go to re-torque them up since you didn't pull them out completely.
Hopefully it will be worth it in the end. After both sway bars I'm going to look into replacing the rear trailing arm bushings. I'm hoping they're similar size to the cts-v. Ours cross reference with srx, but that's not exactly a good lead for aftermarket.
