I just purchased a s5 gtus with a depowered rack(depowered correctly). I decided to drive it today to work and while in the parking lot, while moving, and when I turn the wheel either way to full lock( I Assuming anyways, I didn't keep going to make sure :P) it makes a horrible almost grinding sound. I also tried it a bit later with the car stopped, push the wheels to full lock and no noise, so only when im moving.

Any ideas to what would cause the noise?

Thanks.

 

tires rubbing on the sway bar most likely, non stock wheel offset or tire width.

 

They are stock 16x6 gtus wheels, lowered a bit on racing beat springs, with racing beat sway bar. Thanks for the advice, I'll check it out friday when I can lift it up!

 

i'd still guess it's a tire rubbing issue, somehow depowering the rack may have given it more angle.

 

Yeah that could very well explain no noise when the car is not moving. I'll have access to a lift this weekend and ill put it up there and turn the wheels. Thanks for the suggestion
