Another one of my which on threads

They offer a tighter turning radius compared to the stockers.

They move the front wheels out about 3/8"; not a big deal but make them almost even with the fenders.

They might be lighter than the stock ones, but not sure.
 
Another thing to consider...sometimes with aftermarket control arms or suspension pieces you need to use the company's k-member.

I noticed the a-arms were from AJE Racing. I am not saying they will not work with the stock k-member, but it might be worth checking into.
