Dont kid yourself bro,
the stock bushings may wear out but the factory arms are extremely strong. even after 15 years you are not likely to find many people who have broken a factory control arm.
however, they simply dont provide the adjustability required for cars lowered like ours are.
^^ I was going to say this as well. The stock arms on our cars are really nice. I’d like to see some aftermarket arms stand up to 15 years worth of canadian winters and sometimes 400,000+ kilometers of driving with zero maintenance. If it weren’t for the bushings, they’d probably last a lot longer too 
Oh, and Bing I wasn’t trying to bash your multi-link or whatever, so far I’m extremely happy. And maybe in some cases the hate comes from jealousy but in most of the cases of me getting slack for buying your multi-link people refer to your old chinese multi-link breaking, or the exhausts breaking, etc. which are completely different products altogether so as far as I’m concerned I have no reason to believe there is a single thing wrong with the set(s) I bought. <3
