welcome to nico...there can be a list of problems that can probably create that problem. 1) tire balance2) toe angle/ maybe needing an alignment3) warped rotors?

i'm thinking either 1 or 2...

[evildky]

most likely just the tires out of ballance

Bent wheels perhaps?

Wow. I just purchased a Z that does the same thing, only at 50mph and is fine after about 60. The e-brake is also screwed, as I just posted a new topic screaming for help. So it could be the alignment? Or the wheels? I'm very new to cars, in general, but someone pointing me in the right direction (getting it fixed, telling me how bad the problem really is) would be awesome. I've learned previously that people on these forums are very helpful. I hope that proves true as I need it now VERY bad.

I'd say its either tire balance, alignment, or driveshaft out of balance.

i had the same problem after i bought new wheels, i guarantee that a good balance and maybe rotate will fix it.

welcome and congrats on the Z! good luck fixing the prob

could also be a bad carrier bearing, but hard to diagnose without riding in the car

im 99% sure its tire out of balance, i myslef need a wheel alignment and my car doesnt virbate or anythign at any speed up to around 100mph (havent gone past that) thats usually a comon thing so get that checked out

Old Used Cars that cost $30k+ brand new [Q45 and 300z] all need $3,000 worth of repairs when sold, why sold to bring back to near new performance and operation.

Very few people spend the thousands then turn around and sell at a loss.

New buyers take a while to discover the problems. That's the fun finding out how much you over paid!

Everyone's standards are different and few spend the money to get everything perfect.

Always PAY a Nissan Tech to do a 2-3 hour prebuy inspection/tests to use the outcome in bargaining the final price!
