You have to be careful when using spacers, and be absolutely sure to get a high quality piece. The spacers you linked to are H&R spacers, which are very nice from what I've read. Check out H&R's website for more info.

Also, keep in mind a 25mm spacer is a very wide spacer. You're going to be putting a lot of stress on the lugs, so be sure to get high quality lugs, too. (I think Nismo sells longer stud sets for our cars. Maybe H&R does, too.)

All that aside, there's a fellow on this forum from Australia who put some 25mm spacers on his car with oem Track rims. It looked very nice, and brough the wheels out flush with the fenders. Very good looking.

 

Now that I think of it, Sports Compact Car magazine recently (current issue?) did an article on improving the handling of their Z. One of the things they had to do was use a spacer on the front rims they chose. They discussed some of the pros and cons of spacers, I believe. You might check it out.

 

thanks for the reply
so as long as i get high quality of stud and the nuts...the wheel won't come off from my car while i drive??

 

I would guess that's about right. The lugs breaking is the real downside to big spacers, so you definitely want high quality stuff. I've never owned any, so I can't comment too much other than what I've read.

I just dug up the SCC magazine where they modified their 350Z suspension to do 1.0g on the skidpad. They had to use a 12mm spacer on their front rim, and they stressed how important it was to do it right since they considered this a very large spacer. Anyway, they had BBS rims, so they found that BBS made a hub-centric spacer that is perfect Nissan fit on the hub side, and perfect BBS wheel fitment on the wheel side. This allowed everything to be absolutely centered perfectly.

So, make sure that the spacers you get are designed specifically for the 350Z to ensure perfect centering and fitment.
