Ok, I went to bed last night realizing I spoke a bit hastily in regards to the two sets of lower control arms that Steve posted above here.
I erred when I said they are the same. That comes from the fact that when I was shopping for these in 2011, there was only one model offered in the line that looked like these. They were the BMR part # TCA019, the second pair posted by Steve above. These are the ones I have.
Upon closer scrutiny today, I discovered the first pair posted by Steve above are BMR part # TCA032, which are a new addition to the line since I was shopping some years ago.
The difference between the two is that the TCA019 are TIG welded 1.25" X 2" diameter tubing and are the stronger, sturdier of the two.
The TCA032 are MIG welded 1" X 2" diameter tubing. This makes them slightly lighter than the TCA019 but not quite as strong or heavy duty, although they should still be an improvement over stock.
On AM today, the TCA019 are listed at $139.95 us, same price Steve had on LMR, and the TCA032 are priced $89;95 us. This would explain why the TCA032 can be offered for the $142.47 Canadian price Steve found above. But they are not the same product. Buyer beware.
I realized last night I could have also included a few pics as well of the other parts I mentioned.
Theses are the Caster Camber plates I run.

It is the heavier duty TIG welded arms included in this kit.

SEE DETAILS
As for the K-member brace and A-arm support I use, they both use existing factory attachment points and require no drilling, cutting or welding.
The K-member brace was actually added from the factory by Ford starting on 2007 GT500's and from there slowly started finding its way onto regular GT's at random. Then in 2011 with the introduction of the 5.0 liter Coyote, all GT's got this brace from the factory along with the GT500's.
So you might want to investigate your car before considering this piece as you may already have one.
The K-member brace is a tubular piece of metal that ties the two sides of the rear of the K-member together to reduce deflection of the K-member under hard braking and cornering.
The A-arm support or front control arm brace does the same at the front end of the K-member by tying both sides of the front of the K-member to the radiator support, again to reduce deflection of the K-member under hard braking and cornering. Here too Ford engineers saw a need to brace this part on 2011 and up S-197's. They did it with two pieces of tubing tying the two sides of the front of the K-member to the center of the radiator support in a "V" shape. The Boss definitely has this bracing and I think all 5.0's with the optional track pack, as well as GT500's.
The Whiteline piece, to me, is a much sturdier piece and although the rear K-member brace is available from Ford as an aftermarket piece, the front braces are not. And, if memory serves me right, even if one could source the front braces from the factory, the older radiator supports such as pre 2011, don't have the required anchor holes to fit them. The Whiteline piece uses the existing tie points of the front sway bar with a cleverly designed bracket.
If you plan on auto crossing, you may want to consider these parts to stiffen up your K-member for those quick turns and hard braking.
These and the caster/camber plates, along with a strut tower brace really stiffen up the front end and make the steering response razor sharp.
This is the K-member brace I have.

BMR A-Arm Support Brace - Hammertone (05-14 All) $49.95
This is the factory piece available from Ford by comparison. It's stamped steel only. They use different pickup points. The MBR is tied directly to the control arm attachment point for linear energy absorption, whereas the Ford piece ties offset from that axis, leaving it more vulnerable to deflection in my opinion.
