Default Ok so whats the problem with aluminum control arms?

I was reading in the NA forum where a lot of ppl were recommending against swaping out the front stock control arms with the Sti aluminum counterparts. Something about when you hit curbs and stuff it can cause more damage to adjacent structures. Ok I really don't get it, and is that the only problem?

Also how do these things improve peformance?

the aluminum control arms offer more "stiffness/rigidity" than the stocks... this is a good thing with regards to handling, but it means that the control arms will be less willing to absorb some of the abuse that the car might see - thus transfering the load to other parts of the suspension that may not be able to handle the increased abuse...

I'm guessing that is what they are refering to...

As a interesting side note, the aluminum arms can be had for ~ $330 for the pair (including STi bushings for the rear of the arm- normally ~ $70/pair) vs ~ $300 for the stock arm- that's for one! Ofcourse this only applies to the 02 rex sedan- much more more if GC, GG.

These arms by the way come stock on the STi version. I think it would be a no brainer if someone was unfortunate to damage a stock arm what it would be replaced with. My only reason for not considering the aluminum arm is class restriction in autox.
