it mounts on top of the gold bracket using the same two outer bolts that attach to the chassis
there's not enough room from the trunk floor to the MS bar/mount for the battery to be mounted standing up against the sidewall where the repair kit was located, already looked at that
Mines done except for mounting the battery. I went to put it on the trunk floor behind the right rear passenger seat and several of the mounting holes were lining up with ribbed valleys on the trunk floor. I'll probably use a piece of wood to attach to the trunk floor where needed and then mount the battery holddown on top of it
another consecutive night of only 3 hrs sleep, ugh ...

I sure hope you are smart enough to setup your spanky new coilovers while you have the car on a set of scales. However I think I already know the answer to that, you will just set it to a magical trim height number rather than actually worry about having the corner weights correct.
On top of this you do not even know which battery you have. btw do you still have you washer bottle full of fluid, you car could turn so much better if you drained it. Still have your AC out in front of the car?

Of course I’ve drained it of fluid.
AC will be out in time for Nats $ permitting.
I said its the 37lb replacement one.... if you want me to into why I was unsure there was recently an issue with my main 120V fuse, due to one of those portable jumping units, while trying to diagnose the dealer replaced the battery yet again, don't know which he used this time, pretty sure its still the replacement, talk about a waste of keystrokes.
As for not knowing anything about suspension setups, I already told you that "any additional gain" seen from moving that lighter battery to the back is going to be minimal, and even a toss-up but here is my logic behind it.
Why would I want more load on the tires doing the turning? More load = less efficient = i.e. less grip. Under the same logic by moving it to the rear will decrease the grip on the rear wheels; however, it will be proportionally less because the battery will be closer to the center of the car. Further, the car will have a tendency to rotate easier with more weight on the rear end under this same theory, while I want to retain as much grip as possible on the rear end I also want it rotate easier than it does now.
Like I said we could argue day and night keep it going if you want.

Grasshopper has much to learn, about patience.
As for the grip theory, i'm sure there is 2 schools of thought, but i maintain that tires operate more efficently with LESS load on them. Think about the types of cars that have the highest "g" rattings, are they heavy or light? Do you think a 300lbs lotus driver will generate a higher 'g' then a 150lb driver in the same lotus?
I've always heard (in FWD cars) that unless your wheels are spinning you cannot make the front end light enough.

KW Variant3s are in without issue, ride height is set to 26'' all around; RacingBrake BBK made for Enkei offset wheels is on with a slight rubbing issue (ball joint) to be fixed later this week; and 18x9.5 +38 and 265 AD07 are on with rubbing in the rear end at 26'' this was cured today with one of these.
DIYs to follow tomorrow.

changing direction is a whole different ballgame, of course...

uh, no, the physics are pretty clear: the force of static friction = coefficient of static friction * the downward force (ie, mg), with the relationship tailing off as the force increases due to tire construction and physical constraints of the surface, i imagine. similarly, centripetal force for a turn of radius r = mv^2 / r. if you had enough tire under a tank, so to speak, then it should corner just fine, as both the force required and the force provided are directly proportional to m. :D

and why would changing the mass of the vehicle affect this effect one way or another?

Because in the example scenario I just gave, due to the way suspension works less of the mass of a battery sitting in the rear vs. a battery sitting over the front wheels would be transfered to the front wheels doing the braking/turning.
