LF advice on wheel spacer.
Hi guys.
New owner of a 03 350z here so I'll be snooping around here trying to get some good info from experienced folks like you guys. I'm looking to get some wheel spacers to get a better wheel fitment and would like some tips and tricks beforehand. Some info you may need. Car has stock suspension from what I can tell from wheel gap. No plans on lowering it further. Front tire is 225/45/18 and rear is 245/45/18 |

Car has stock suspension from what I can tell from wheel gap. No plans on lowering it further. Front tire is 225/45/18 and rear is 245/45/18 With that "narrow" of a wheel, you could even go to 20mm spacers but 15 is adequate. Make sure you get hubcentric (66.1mm), 5x114.3 PCD, 12x1.25 thread pitch. |
If your going to use spacers change out the studs for some arp's and get a slip on hubconcentric.
Z1 sells a kit for like $120 for 2 spacers and 10 studs. So $240 and then some open ended lug nuts so say $300 and your good... Then again you could put that $300 towards a set of wheels that fit without spacers. |
I agree smart decision would be put that towards a nice set of wide wheels, but I'm looking at a hefty investment with wheels/tires.
I have fairly new tires on the wheels now so maybe once the tires are worn out it would be time to entertain that option. I would really like a nice set of deep dish wheels obviously but $$$ lol. I spoke to the previous owner and here's what he said about the wheels that are on the car. He believes that wheels are 8" front and 9" back and 35mm offset. So he claims Would there be a way for me to verify this information? Currently I'm looking at buying 4 66.1 Hubcentric 5 x 114.3 20MM wheel spacers. 12x1.25 studs and new lug nuts. Now as far as price / quality of these spacers. Does it matter? Are more expensive ones better? Previous owner said he had fit 1.5" spacers front and back (how he got that to fit beats me) and he said that over 100mph there was a vibration in the car. Something I obviously don't want. Currently I've hit 230km/hr and there was absolutely no vibration or rattling nothing so I'm happy with how solid it is. I would like to be able to maintain this as much as possible. Although I do wish to have a better stance also. I appreciate the comments and suggestions. As always I'm here to learn how to do things right, and who better than you guys to look for advice ! |

If they're not OE Z wheels, here's how to measure width and offset:
https://my350z.com/forum/wheels-and-...t-novices.html Thanks for the info! So lets say for theoretical purposes. Lets say the previous owner is right the wheels are indeed 35mm offset or close too. What would the recommended spacer size be front/back? Just for proper wheel fitment nothing too extreme that will throw rocks at the side of my car. |
If they are 9 inches wide with a 35mm offset 20or 25 mm spacers would work fine.
Their is a tire and wheel calculator in the tools section on top of the forum. Post a picture of your car we will have a better idea about what wheels you are talking about. It's amazing how many people have no idea what their wheels specs are and if the previous owner didn't have a confident reply when you asked about the wheels chances are he was guessing. |

But it doesn't appear that that mishap was from spacer failure (unless the threads stripped). Looks like a simple case of "We don't need no steenkin' torque wrench!" :icon17: |

Ew.

Looks like a simple case of "We don't need no steenkin' torque wrench!" :icon17: But it also had slip on spacers with stock sized studs so who knows, a dude I work with sent me the picture. He said it wasn't fun loading into the truck. |

I think it was a matter of 370 wheels with tuner style small lug nuts.

If you do it right, you will be fine. In my opinion, I do not like slip on spacers unless they are under 5mm. I would go with bolt-on spacers. I have had my Z1 spacers for about 6-7 years now with 0 issues. 20mm front and 25mm rear. Just make sure they are torqued properly and you are using the correct lugs. I went with Gorilla lugs and they have been perfect. |

Just the opposite here, I like slip on spacers up to 20mm paired with ARP studs.
My Jeep on the other hand has 25mm bolt on spacers My only experience with spacers is my bolt-on Z1 and they have been perfect for me. Super easy to install and virtually no maintenance. |

I see your point. I am not opposed to slip on spacers, as long as longer studs are installed. Only problem is that many people do not install longer studs, and then you have something happen like in the picture posted.
My only experience with spacers is my bolt-on Z1 and they have been perfect for me. Super easy to install and virtually no maintenance. Happened 30 feet after I got home from a 900 mile trip running a chase crew for Vegas to Reno off-road race. My wife took the Jeep to the gym and it failed right out of the driveway. All 5 studs snapped, none were cross threaded. I removed the snapped parts out of the lugs, removed the spacer , bolted the wheel back on without the spacer. Moved it back to the driveway and removed the other spacers in the morning. |
I have had garage-line spacers on my daily for 25k miles. I have had garage-line spacers on my Z for 15k miles. I might be lucky or they're built well.
|
get hub centric and torque them down with locktite.. also anti seize where they touch the rotors. Re torque after a few hundred miles and check periodically.
I've had 25mm spacers on for years and no issues. |
