Thanks for post. That is my next step. Have booked car in to p/beater next Monday to fit noise to wheel arch's. My panel shop man took the car for a drive and could not believe the road noise.

Good to know that the wheel arch did the trick. At least I know that I am on the right track. As a matter of interest how long did it take him and what material did he use? Will post results.

I purchased 2012 Aurion ATX at 21000ks. Very disapointed with road noise. Fitted a new set Michelin Premacy at 5ks. Very little improvement. Decision get rid of car and loose a small fortune or spend a few dollars chasing the noise. Great car, good on fuel, plenty of power and great boot. Made decision to chase noise.

Purchased a noise insulation kit from Tru-fit for $150.00.

Step 1 Fit noise insulation ( per a local panel beater @ $300.00 ) to the inside of each door. Noticeable improvement to the point that we have been able to isolate noise intrusion to area around wheel intrusion into footwell.

Step 2 Fit insulation under trim and floor mat on both driver and pass. sides. Will advise results.

Very disapointing that a world leader in the automotive industry can manufacture a car with so little insulation against road noise. A friend recently purchased a 2015 Corolla and here I am complaining about my Aurion. Its quiet compared to the Corolla.

I also have a 2014 Ford Ranger 3.2 diesel 4 x 4. Road noise is substanially lower that the Aurion ( before noise reduction ).

Recently hired a 2015 Commodore whilst interstate. Boy! what a quiet car.
