Ultimate 4x8 utility trailer, 2,700lb capacity with brakes

This is what I have been moving toward with the odd questions I was asking.

Pretty much a ground up rebuild.
This trailer started out as a bolt together motorcycle trailer with about a 900lb capacity in 2004. I got it in 2008 and rewired it, put a new hitch on it along with better tires, axles and springs.
Last time this trailer went under the torch was 2012. I converted it from bolt together fold up to ridged welded frame. On top of a 2,000lb idler axle and about 1,800lb worth of tires.
On my road trip last year I could feel the deficiency in the tongue design on very rough roads, roads in NY are worse than I have seen in war zones, WTF is up with that. And the mild 800lb gross trailer weight was pushing the car around a lot more than I would have liked when I tried to stop.
So it's getting a brake axle and new tongue design.
The spindles are ez-lube brake hub ready spindles rated 1,350lb each using 1-1/16'' inside and outside bearings. The axle is a schedule 80 steam pipe measures 1.5 inch inside diameter.
Ez-lube means that the spindle has been rifle drilled with a small hole from the spindle nut to between the grease seal and inner bearing. They should probably call it lazy lube. The only reason I want it is so when I get a surprise long distance trip I can hit the bearings with some grease with out taking the spindle apart.
It's still a good idea to clean and really pack the bearings every 2 or 3 years.
The axle and spindle are at the machine shop being machined down to fit together, I weld them.
The spindle bases are bigger than 1.5 inches, so they don't fit into my choice of axle tube.

Looks like the tires I will be going with will be load range E 145/80R12 rated for 1,600lb each.

Total cost of the brake axle up grade is going to be around $550.
The brake drums, brake set and spindles were all about $270.
The tires and rims will run about $200 for the pair.
Heavier springs are $25 each at the local trailer supply.
6 foot of schedule 80 steam pipe was $24.
I didn't ask how much the machine shop was going to charge.
And I need to find some U bolts.
I should have all the nuts bolts, hangers and shackles.
If you wanted to do one your self you could definitely save some $ by going with cheaper tires if you don't need load range E and if you stuck with cheap steel rims or even better, used steel rims. I want new aluminum trailer wheels.

You may think 2,700lb gross and around 2,400lb capacity is way too much for a car. IMO a 800lb gross weight no brake trailer is too much for most cars. but I also have the suburban and the over powered big brake firebird.
