Hi and welcome! Its good to see a new build up coming through. A couple of comments that I have:
Front end:
Those Empi adjustable struts are DREADFUL. They rely on a thin wire retaining collar that IMO won't last long with potentially lethal results. Where the grooves are cut for the wire seat they reduce the wall thickness of the struts by about 50%. These struts are not an engineered solution and I sent mine back after seeing the items in the flesh. If you are after the adjustability then a threaded collar with 2 1/4" springs is the only way to go. Iif you do lower then you will need to flip the trackrod over as it will hit the AR bar at -2" that will also have to be flipped to give a better angle of operation.
Don't bother moving the battery up front because at present it's sited on the neutral axis of the chassis so it has little effect on the handling traits in that position. Moving it up front adds little to the axle load but increases the polar moment of inertia measurably that may dull the chassis reactions. Also there is the penalty of running a starter cable the length of the cabin.
You may not be able to achieve 3" lowering with adjustable struts as the track rods will cause allsorts of interference problems. 2"-2 1/2" is the normal max lowering that will be beneficial but at that the chassis may hit on some of the bumpier sections.
Have you considered what springs/dampers you require?
Apart from that the front end will be well nailed.
Rear Suspension
All that looks fine but I assume that you will be running standard TBs? If so the standard 22.5mm TBs will be a bit soft for a quick/fine handling car. They ideally need uprating to 23.5mm for fast road/occasional track use or 25.5mm for a more competitive car. You can instead add coilovers in lieu of using the uprated TBs but the top mount of the coilover needs triangulating with something like a 5 point kafer cup brace.
What's the brake spec? I would be very cautious of some of the aftermarket rear disc conversions as they don't balance well with what's available for the front.
I assume that by 4 point rear bar you mean a rear hoop only with two rear struts. It would be well worth looking at a full cage as this provides extra torsional rigidity to the shell.
Keep us all posted on progress
