Thinking about putting some wheel spacers on to make my rims "pop" a little more, I don't want them sticking out and looking stupid. Which ones should I select? I know most go front smaller, back bigger is this correct? Will the OEM 19 g37 rims rub? Which is the best brand for the price?

 

Does this look right? Looking at the ones from : http://www.motorsport-tech.com/4DCGI/a_diameter.html

Also looking at these: http://www.trakplus.com/

But don't know the wheel gap or which ones to order on the page after it.

 

Not sure about the quality, but the price is very nice Anyone out there try these??

I have 20/25 on my 03 coupe running stock 18"s as my winter set up. In my opinion it is the best set up.

The the classifieds.

 

I never cared for using spacers, but if you absolutely have to, then those hub centric, one piece, bolt-on, wheel adapter type shown in your first link are the only ones I'd ever consider. IIRC, Motorsport-Tech used to be located in socal, so they must have moved to Nevada in just the last few years. Properly installed, that type of spacer is far superior to any "dummy" spacer. Likewise, if you go with the HR spacers, then the DRM is the only type you'd want.

btw, Motorsports-Tech allows you to select differences in sizing between front and rear to your exact custom specs, not just 5 or 10mm increments.

 

No, but off the top of my head, it bothers me that they don't list any hubcentric measurements for their fitment to your hub, they don't replicate any hub lip for aligning your wheels to them, they are no-names of unknown origin and quality, and my life is worth more to me that saving a few bucks. Other than that, who knows . . . maybe they're just fine.

 

You seem to know your spacers, they kind of scare me too. In your opinion what type is safest, the ones that just use longer studs or the kind that you use stock studs and then the spacer has new studs for the wheels ( so 10 studs per wheel). Seems like the longer studs would be better (although longer studs may be weaker) since you could easily check the tightness of the wheel rather than having 5 concealed bolts underneath that may be getting loose. What do you think??

 

The best way to determine the right spacer for your needs is to measure the distance you have between the wheel and the fender/quarter panels.



I think if you're planning on getting something pretty large though, you should get the bolt on type spacer, rather than get longer studs. If you torque the nuts down properly they should not come loose.

 

Isn't the trackplus ones bolt on and good quality? I had thought I had seen a few guys with them. Also, will I be rubbing with the 19"s?

 

I have the H&R Trak+ and think they are great spacers--much better than generic Ebay spacers or even Ichiba V2 spacers. Got my set from FRSport.com. The 19" G37 offset is more aggressive than the 18" sport rims to which people are running 15-25mm spacers (stock to dropped suspensions). Unless someone with 19" G37 rims chimes in, your best bet is to mount the rims and see what thickness spacer you should get.

Best way to accurately determine the right spacer size. No guessing games there!

I don't plan to drop it, would 20mm all around look good?

I'm looking at making them custom since they don't show them for infiniti and it's asking for the "center bore" size, is that the "hub diameter'?

Pulled this from motorsports website for my car.

The hub of your car has a diameter of 66.1mm. To make them wheel centric you need to get the bore of the wheels (diameter of the opening that rests on the hub). If you're using stock wheels it should be 66.1mm.

 

I'm not exactly sure what the measurement is for the center bore of our stock wheels. If our hubs are indeed 66.1mm, and our wheels are able to "slip" on them w/o a press fit, then I figure there MUST be some extra clearance there. SO, I suspect that the center bore measurement is something SLIGHTLY larger than the hub, but I could be wrong. Rather than try to spec out the center bore for a particular wheel though, I think I'd approach it by asking them to just replicate onto their adapter the exact same size lip that the hub has (ie 66.1mm or whatever). That way, your wheels should fit identically to the adapter as they would if the were mounted directly to the hub. Doesn't that make sense?

Better yet though, I'd suggest contacting the manufacturer and getting their input; no sense risking an error on a custom built part.
