i was looking into getting new wheels for my Z , if i do , id have to get a new tire press system ? is that a must (dont want a light on all the time) ? can i just use the existing ones in the new rim ?? i didnt even realize the 370z had a pressure monitoring system

Yes you can use the one's in your rims now. You'd have to have your old wheels broke down an the TPMS switched to the new rims.
For me, I just didn't want to break down my stock wheels.
I am leaning more and more to just leaving them out of the new rims....

why wud u just leave them out tho ?

1) cost of breaking down the old set
2) cost of buying new TPSM 430.00
3) It's a weekend driver, so if I can't check the air before heading out somethings wrong.
4)**** happens if I get one I'll deal with it.

Bro your in luck! Look over in classified, someone is selling the TPMS from their 370 on the cheap:tup:
