bent control arm Audi A4 2013 Aftermarket replacement??
 

So I took my car to an alignment shop after sliding into a curb sideways. They said I bent my front left lower rear control arm. Apparently the rest of the car is fine. (It just started snowing after being completley clear and it was very slippery) Guy infront of my didnt signal or use his brakes just came to a rolling stop. I swerved around him sliding, tried to counter steer and hit a curb sliding sideways.

My question is would an aftermarket one be ok to replace it? I live in canada so if i do should I go with altram which is 450$, dorman for 250$ on sale from 430$. or should I just get these 2 for 367$ canadian + shipping . https://www.ecstuning.com/b-megan-ra...s-au-1911~mgr/ and replace both? The genuine audi one is 640 on some sites ~ 720$ at audi dealership.
