SO i put on my TEIN 350z S-Techs the other night and have been driving for a lil bit, and last night it was dead silent on teh roads and not all that bumpy and i had the window down, and I have a 03 6mt coupe but when acellerating slowly and steadly (only when lightly on the throttle) at aroun 25MPH+ this squeaking noise becomes present, when i let off throttle it seems to stop when i get on it kinda hard it stops, only when cruising on steady throttle. Its really annoying and it just goes squeak, squeak squeak squeak squeak as im rollin down the road. ANY idea what it might be? my camber is terrible and im puttin on the SPC adjustments today so im hopeing it was that but its only the rear left that seems to squeak. anyone no what it might be? thanks!

 

my wheel bearing was shot and i had a grindig noise, but i doubt thats what your problem is since you just lowered it. check maybe the dust shield on the rotors maybe it got a little bent and is rubbing the rotor a little
