So I dropped my with 350z H-Techs

and now the road noise is pretty loud.

what should I do?

alignment? wheel balance?

 

Alignment would indefinitely be your first step. How worn down are your tires? Camber wear is definitely happening. You may want to consider getting front and rear camber kits.

 

yeah I think so too... I'll probably order a rear camber kit first and see if that works out...

should I wait for the order to come in and then go get an alignment or can i get an alignment and then add the rear camber kit on.

 

Get alignment 'after' kit put on....

 

i have the same issue as you do. although it wasnt as bad, or too my knowledge as bad as when i had my springs put on, but i had the front rotors and brakes installed. the rear, from what the tech said, didnt need to be replaced. after that my wife said the noise seemed to be louder but i honestly cant tell the difference.

 

HAHA, those of us that lowered our G35's and didn't install the adjustable a-arms are very familiar with the noise you're describing. We refer to it as ROOOAAARRRR, and is normally heard below 40 MPH. You can't turn up the tunes loud enough to hide it, and it's eating up those front tires. Get the toe kit for the back end and adjustable a-arms for the front....Oh and you'll need new rubber for the front along with an alignment after install! Our MARKETPLACE and vendors have what you need at a reasonable price. I bought everything from ARTrace, great guys!
