I just put the 18x7.5 6th gen 18"s on my wifes car and as expected the rear sits in alittle to much. What spacer do I need to get it closer to the front fitment? Thanks for the help

 

Measure how far out you would like them to go (in millimeters) and then buy the appropriate spacer. If you need 10mm, for example, then buy 10mm spacers, and probably extended wheel studs would be a good idea. It's fairly straightforward.

 

What's the offset on those wheels? I think a 15mm bolt on spacer would be perfect.

 

Iirc a (custom) 12.5 mm spacer would make the front and rear the same. Anything from 15-20mm will do the trick. I'm running a 20mm spacer in the rear, looks great.

 

They are +40

 

whats the most you can do without lugs?

 

10 mm spacer to match front.

Rears sit in 10mm more than front.

 

eh? you mean the biggest spacer size without replacing studs?

I would say 8mm-10mm MAX because you want to make sure your lugs complete the necessary amount of turns for safety,etc. Anything more than 10mm would either be replacing studs for longer ones, or get bolt on spacer.

 

Last question, what should I look for when buying. Do they need to be hub centric or do anything

 

IMO H&R Spacers are the way to go, IMO. They have a variety of types. (DRA/DRM, etc)

My 5mm spacers came with extended wheel studs.

 

They don't need to be hub-centric but if you can find hub-centric in your price range I recommend that you get them. Keep in mind Nissan hub is 66.1 if you opt for hub-centric.

I have used both bolt-on and slip on spacers. From off-brand, custom, to eibach. H&R are popular, as well as Ichiba. The Ichiba V2 (Version 2) are the bolt on type.

That varies depending on the wheel. I had 5/16" or 8mm cheapies spacers with stock wheels and there was a good amount of threads left. Once I got new wheels, enkei rp02, they did not seem enough. I've read seven turns on the lugs is safe. Still I would not recommend sandwich spacers of any size with out the matching extended studs. I also recommend hub centric for safety and vibration free install. Hub centric are only available on the thicker, bolt on style.

 

It's happened to me before...not enough threads for the lugs. Believe me, get as much as possible.

2 lugs came off, 2 lug studs broke off at the same time and wheel came off driving very slowly trying to limp into a parking lot off a busy street. No damage thankfully, but lesson WELL learned.

 

Do it right the second time and get bolt on spacers and re-torque at least 3x.


Or do it right the first time and get the size and offset wheel you want.
