I have an 04 350z and i wanted to see what size spacers i should run in the front i have some 10mm spacers in my garage but i feel like that to big i do have my fenders rolled in anything helps thank you

 

Welcome- but to gain any kind of advice, you need to post wheel/tire model, size and offset.

 

245/40/18 there esr i think the offset is 20

 

^^^ So much this.

ESR wheels for Z are either going to be +22 or +30 depending on which model and exact size.

What is your objective with spacers? I assume flush fit. If they're +22, you should already be fine if you're running the standard/correct stagger configuration 245/40F and 275/40R. But again, this is just speculation until we know exactly what size and offset they are. Just pull the wheels, they "should be" marked on backside of the hub pad or spoke (if applicable) somewhere.

 

Im running 245/40/18 square but i put 11/2 spacers in the rear and it sits pretty flush
i just wanted to see if 10mm spacers are a good chiose im have 1in of space frome the tier to the fender

 

If you want the wheels to sit flush with the OEM fenders, around +12 to +15 offset will be pretty flush fitment for the front, and around +12 for the rear.

However, this depends on your suspension (how low the car is), how much camber you are running, as well as the width of the wheels.

A 245 tire will be pretty stretched on anything more than a 9" wide wheel. This means you may be able to go lower offset, depending on how far you want the wheel to stick out, and not rub the tires on the fender. Keep in mind, the lower your offset is, the more likely you will need to roll/ pull fenders.

Also, anything over a 5mm spacer should be the hub-centric, bolt on style, for saftey reasons.

 

So 10mm spacers are good?? Im only -4 camber all around

 

 

Okay thanks
