I have a 350z base model n my front rim cracked they said I need a new one which its 800 at the dealer but they also said I could get it repair. I'm not sure what to do.

 

Used OEM wheels are dirt cheap here and on craigslist. You can buy a full set of 17s with tires for around $300-400, 18s with decent tires will be more. I have seen members part out a set and sold single wheels as well.

 

Also your title was horrendous so I fixed it OP

OEM wheels are a dime a dozen here on the forum or elsewhere

What year is your Z?

 

Just get the track V1 set.
