Body frame/suspension

Hi guys! Today I caught a deep road whole going at around 35km/h with right front wheel. It felt like right front body frame bent up and then slowly bent back. I have old 2005 Impreza 2.5RS. I bought this car used and believe this same right front frame was hit before as it looks like right front fender was changed before. Also when you look down under the hood, the frame on the right side seemed with a different welding marks then on the left side.

Any opinions guys? Otherwise car looks and drives great. I am thinking I should install struts bridge to re-enforce frame?..
