Mazdaspeed Reinforced A-Arms?

I'm rebuilding suspension and steering components and I was reading the article in the second Forever MX-5 magazine. They were rebuilding their suspension and steering on their high mileage project car. The article mentions they used reinforced upper a-arms from Mazdaspeed.

What did they change and what are the advantages?

Cost over OEM upper a-arms?

Part number for the Mazdaspeed a-arms?

Reinforced?

I've never heard of anyone damaging an upper one (other than in a fender bender).... Lower one, yes...

Never heard of them.
+1 They don't break or bend, the long bolt turns into an "S".

The upper A arm must be pretty beefy then. Those bolts are no joke. 100 ft/lbs TQ'd right?
