question, on my 01 grand prix SE, both of my rear trailing arms are bent/kinked. Ive never got hit or did anything to kink them. Im curious to why both sides, left and right rear trailing arms would be like this. are they that weak??

Factory shape is like a U persay, aftermarkets are tubular. should i stick with some factory ones or grab a set of aftermarket. This car has no mods what so ever, but id hate for them to bend again..

what kind would you recommend. thanks
would this even work??http://cgi.ebay.com/ebaymotors/Dorma...item51967344bb
