Do you have any closer pictures of your wastegate setup? From the pictures, it looks like you are keeping the up-pipes divided into the flange and running a merge in to the wastegate flange. Any issues with that setup? I'm thinking of doing something similar, but can't decide. Thanks.
I don’t have any other pics handy but your description is how it’s run. I have to say the WG works very accurate this way. It has a 7lb spring in it and when I disable the boost controller, it builds boost to right around 7psi. With the boost controller enabled, every 10% of duty cycle adds 1 psi of boost so it makes setting and knowing the total boost very predictable.
 
Awesome, thanks for answering. I have both a divided and undivided flange on hand but can't make up my mind on which to use.
 
Little closer. Everything is tight around the gas tank, but clears. I’m pretty confident I can get the rear 2-3” lower than it was before and have plenty of room for compression. I have a good idea how I will position the shocks but am running out of space for an anti rollbar. That’s gonna take some thought and mocking up a few ideas.

That is looking great. Build a crossmember that goes through the floor and put the roll bar in the trunk.

I'm not a chassis fabricator by any means, so this may be a dumb question. Shouldn't the adjustment holes on the lower bracket be completely vertical? I've never seen any on an angle like this. Maybe it's the angle of the photo?

With that style of bracket and as many adjustment locations as he has it makes really no difference what angle the bracket is mounted. He can realistically put the bar wherever he wants it.

The holes themselves are placed with a very slight radius and the bracket is mounted about 5 degrees back. It’s weird but per the vendor this should allow movement of the bar up and down within the sweep of the holes without having to adjust the bars too much. Plus the car is jacked up in the back making the angle look exaggerated.

Makes sense....
 
Played around with ride height today. Don’t think I can get it as low as in these pics (gas tank is suddenly an issue) but I think I can tuck the tire up there a bit.

Does your pinion snubber not touch when it’s that low?
 
That’s looking great! Do you already have the new shocks and springs?

That’s the next step. I need to rehang the rear, figure out where I want the upper part of the shocks mounted and then place an order. I’m trying to get as long of a shock on there as possible.
 
I’m about to throw in the towel on retaining the factory gas tank. Everything is just so tight that I’m afraid if the rear gets into any weird angles like turning up the grade into my neighborhood, there might be contact. It pains me to think about cutting up the trunk area any further and installing a fuel cell, but that might be the only path forward.

I’ve moved the shock height adjustment to the upper mounts. I’ve probably done 20 different things backwards just to keep the gas tank.

I meant an actual cutting at say, the curve part of the tank and making the front a flat piece of metal. I could draw a picture better than I can describe it.
How about this way, cut three inches off the front of the tank and put in a flat sheet of metal. Not sure where that messes with the sending unit if it's being used.
 
Just dent the tank like a set of headers. Piece of pipe the same diameter as the shock and a BFH. Might look like poo but you could probably make some clearance
