So I changed my springs back out and put the H&R Super Sport springs back on and ever since I put them on I have had a vibrating noise in the passenger front wheel area! I've checked everything and everything seems tight! it only does it at low speeds and when turning right but never at higher speeds(above 30mph) or when I turn left! Any reason why? Any help is greatly appreciated guys!Also I just put new brake pads on last week if that would have an effect!
