Vibration Problem
 

Hey guys i dont know if this is a dumb question or not but i just bought an RX8 and first time taking it on the highway. When im under 100km/h the car runs smooth, but once i pass 110km/h the car goes though this pulsing vibration. I dont know what it is so maybe someone can shine some light on this. Thanks guys

What tires are you running? Some tires have a significant 'thump' at higher speeds. But then, 110 km/h (68 mph) isn't very fast.

yep..sounds like suspension to me as well.

I've had my car to 137 MPH and it was tight to the rode.

Get your wheels balanced.

your tires need balancing.
