Just purchased '05 G35 AWD (clean CARFAX, dealer I trust). Drove it for about 10 days and 500+ highway miles and generally happy with car. Tires were going to need replacing soon so bought 4 new at local NTB store (Yokohama AS530). Wheel balancing and 4 wheel alignment done with install of new tires.

Car felt different on local streets and definite vibration at highway speeds. Took it back to NTB and they said that the 2 front tires were out of balance and the alignment was out of spec (after about 50 miles???)

It seems better, but still not right. I plan on taking it back to them again, but any ideas?

 

if the car is lowered, it'll never be back to oem specs.
MAybe last owner had it lowered...

 

Man you need to take your car to a better shop

 

I'm pretty sure it hasn't been lowered but I guess it's possible - it would seems like if someone wanted to lower it, they would lower it enough to be noticeable?

The quality of that shop is definitely a question.

 

yea try a different shop, Most of the new Hi-tek places have people that work with what they learned in books.
Sometimes a small shop, thats been in business does a better job, cause he actually performed such jobs before.
Like in Brooklyn, Ny Most of the lowered g35s end up going to a small russian shop, just because one of the mechanics knowns and has experience with lowered g35s...
