Default Its HERE!!! And now the questions!

Just picked up my first C5...(99 FRC, only 14k miles).
Car is awesome! Love everything about it. Had to drive it 6 hours home. Now.....it seems to me when up above the 40 mph mark I hear either rear end or rear wheel bearing noise? Is this possible with such low mileage? Or is this road noise? runflat noise? Maybe just normal and I am panicing?Yea...thats it....I'm panicng right?

The run flats are rather noisy. After I put non-run flats on, the noise dramatically decreased. I wouldn't think there's enough miles yet for bad bearings. Congrats on your car!!!!

It's probably just road and runflat noise as Vetts have no sound dampening. Mine's a bit that way - not even close to being as quiet as my Acura. We did this thread a couple of weeks ago and it was very interesting.

Keep in mind the FRC has less insulation than other models.

As a result, you will hear more noise and feel more heat than the other models.

My car seemed very quite (relatively) after going to non runflats, but after some miles, tire noise has returned.

I'm convinced that wide tires are going to make noise with age, so don't count on tire replacement as a cure.

If it turns out to be road noise, do a search on various threads about sound deadening, and the different kinds of materials you can use for this. Ensolite, dynamaxx, and even good old Frost King foam from Lowe's works for this. Check it out, and welcome to the forum.

The noice you are probably hearing is the torque tube (it sits in the hump between the seats.

Lack of insulation and runflats don't help any. I doubt you have whell bearing other problems.

Other noise solution is to install a partition.
