Front control arms

Are the front control arms steel or aluminum on the facelift models?
I am removing the kmacs bushings, they squeak and chatter to much for me.
My concern is pressing the original bushings back into the arms, if the kmacs made the hole too big the originals won't seat well. If the arms are steel we can heat and shrink the hole to make a tighter fit.
Guess well see what happens

Had the same issue as you with the Kmacs till I found the right grease for it. No more squeaks. As for the arm, it felt light when I installed it so probably alum.

No issues going back to stock
Anyone looking for a set of used (5k miles) front kmac's bushes? Can ship'em for cheap. PM if interested

Front control arms are aluminum.
