This is my first time posting so I apologize for posting in general chat.. But hello, I'm Sarah and I have 2007 Versa.

I got my car put on TEIN S Techs last Wednesday when I started to notice this very subtle humming noise. You wouldn't hear if you weren't paranoid like me haha. It's coming from the passenger side and I feel like it's the rear but I could be wrong. Might I add that I'm riding on the tread bars but the only time I can produce the noise is at around 40mph or higher. The car hasn't been aligned yet and I don't think it's a wheel bearing problem as it's not loud enough.. anyway please share you thoughts on this. Thank you in advance!
