Those of you with wheel spacers on, how long have you had it on and did you or now having some sort of wheel problem because of it?
I've heard it puts stress on the wheel bearings and studs resulting premature wear. Im thinking of putting 25mm all 4 and will keep it on till i have the car.

 

I've had them on my car for nearly 2 years - 0 issues. We have hundreds of customers with them on Z's as well, without incident

 

I do believe the myth (not sure if true or false) is that spacers on mostly track cars is bad, for the reasons mentioned.

 

I prefer the spacer that includes longer studs vs the type that bolt onto the existing studs - these are all I have ever used personally. Porsche includes spacers on both GT3 and GT3 RS from the factory (and I think one of the Boxster models too IIRC)

 

so it shouldnt be a problem for daily driving use

 

No sir, lots of people use them. It`ll only be a problem if you use them and youre wheels still suck offsetwise haha

 

i have the project kics, hit 100+ mph without any vibration or shaking

 

Not a fan of hub centric spacers? I have to get some relatively large spacers to fit over the stop techs and the rpf1's. They wheels are of a scca t2 car i know for a fact he runs 22mm on front and 8mm on the rear. If spacers are good enough for national level t2 race team.......they will put up to the stress I will put into it quite easily. From what I could get out of him though.....they are custom milled with arp studs.

 

Agreed. If T2 cars choose to run them and do-so without issue, that's enough "real proof" for me that they can be used without issue. BTW, I don't believe you'll need one in the back. I think they chose to run the 8mm spacer to get a slightly wider track, but the 18x9 +35 rear should clear without issue otherwise. I have mounted 18x10.5 +43 without issue on the rear, though I chose to run a 25mm spacer to get a wider rear track.

 

The rear isn't really the worry as you said, but I am going to have to do some finagling to see what I need to fit over the front stoptechs. I'll probably add a spacer in the rear.......perhaps 10mm.....haven't decided. I'll just play it by a year when I get them on sat.

 

Wheel spacers come standard on lots of high end sports cars. Take for instance the... well I cant think of any right now.

 

The spacers I use are hubcentric (66.1mm inner bore, specific to Nissans), they just use a longer stud that replaces the factory ones. I prefer that type over the spacers that bolt to the hub. Reason is that with the ones I use, the wheel is still bolted to the car. With the other type, the wheel is only bolted to the spacer. I feel more comfortable the other way. They both work, it's just my personal preference. People use the bolt on type because they are far easier to install (no worrying about removing the stock stud and installing the new ones). I just feel better knowing the wheel is bolted to the car the way Nissan intended it to be

 

GT2's and GT3's come with spacers from the factory on the rear wheels.

 

thats interesting,..do you know why they did that?

 

95k miles on 25mm spacers front and rear. No issues.

 

Does it add stress to the bearing, YES. Some bearing, hub assemblies are very durable and can handle it easily, some can't.

I run spacers on my car, daily driven, and beat at the track. As long as quality parts are used, spacers arn't a problem.

All mine are slip on style, and i run 60mm studs.

 

I have the Ichiba hub centrics as well and I love them. I just recently installed them and so far zero problems. I have the 25mm on the rear and 20mm on the front, almost perfect flushness for my current set up, only reason why I'm not hella flush is b/c I'm super lowered and have a pretty large neg camber, so I didn't want to rub/roll my fenders.

 

I tried to find some pictures of the interior of RPF1s to see if they had space for the lugs of the bolt-on spacers. It looked like there was some room, but I couldn't tell how much. I'll likely get longer studs all around and run the slip-on spacers. I'm not going to buy anything until I have them and can take some measurements to compare to my calculations.
