I bought the car which is G35 Coupe few days ago and the previous owner pretty much tune up everything. he run the car on 17 Sedan wheels . I then bought the 18 oem wheels today and put on the car by myself. I drove a little bit but feel the brake and suspension not the same as before. Do i need to bring to mechanic shop to re-check the suspension system and brake??

 

Probably needs an alignment

 

awesome I go get it done now. thanks alot

 

Let us know how it feels!

 

Brand new tires or used tires? If used tires, it's possible also if they're not staggered and all the same size, that the tires are worn in a direction that is counter to the direction of your car and tires are in.
