Why is My Rear Suspension So High Up?

Over the past couple months I have parted out all the high performance stuff off my 2000 T/A and put everything back to stock (mostly). For some reason my rear suspension is making the car a lot higher up back there than it seems like it should. It's a complete WS6 suspension off an 80k mile car. I had previously cut off the original LCA mounts to install bolt-on LCA relocation brackets and I'm wondering if maybe I have them positioned wrong for a stock ride height or if that's even the problem here. I'm trying to fit on some 17x11 ZR1 wheels with 315's and I need the bump stop to move down to where it's inside the lip of the rim (which it SHOULD do) so that everything will clear. Even when I tried jacking the car up by the rear end with the parking brake off, I didn't get much upward travel before it started to lift the whole car. When I push down on the decklid, it seems like the suspension bottoms out on something before going much further down (in relation to the rear end). Here are some pics of the rear suspension:

This is where I thought the LCA's were supposed to go for stock ride height (correct me if this is the issue):

I got the LCA's put back in the original position, but it didn't help much at all. Still no where near as low as it needs to be for my wheels to clear the bump stops. What now?

That's what I was thinking, but there is a guy with ZR1's just like mine (same backspacing) who claims that he got his to fit by jacking the read end up until the bump stops were on the inside of the inner wheel lip so they would clear. He didn't say anything about his car being lowered or doing any mods like the "heater hose", but I'm thinking that he must have done something different for his to clear. Do my bump stops look like there are in the correct spot for stock ride height to you guys? If so, do you think 1/4" spacers would make enough difference to get the wheels to clear (I really don't feel like putting in all new longer studs at the moment)?

This is no surprise, these cars sit really high stock, and if you keep jacking the car up your only making it worse because the stock springs take some time to settle back down. Grind the side of the bump stops if you can, run a spacer and maybe do the heater hose mod.
Why did you go back to stock anyway?

But it's rubbing to the point that I'm tightening the wheel onto the bumpstop so that it never has a chance to free up and drop down. I already had the car on jack stands working on the transmission cable. I figured I would just go ahead and jack the rear up and put all the weight of the car on it (for a few days), but its just not sinking down enough. I guess the front tires need to be on the ground for the pinion angle to allow them to clear cause I'm telling you guys, when I push the decklid down, something is making it bottom out way too early and it won't go too far. Like I said, it must be the pinion angle. Either way, I guess I'm gonna grab some cheap 1/4" spacers and maybe even grind on the bump stops a bit this won't even be an issue anymore.

I had some major issues after my twin turbo setup and had to part the car out to get the majority of my money back out of it. I was gonna just sell the car as a roller, but it's such a nice car and I got some good deals on parts and since the used car market seems to be coming back up strong (especially for fairly low mile T/A's), I decided to put the car back together to sell for someone else to enjoy.

When and grabbed a cheap set of 5/16" spacers today and grinded on the bump stops a little. Everything clears and maybe after sitting on the ground for a while, the car will settle down to where it needs to be.
