If you don't have any aftermarket wheels then don't even think about spacers. If you want aftermarket wheels then go ahead and do a 5 lug conversion and know what exact size you're looking for by searching through the bazillion pics of wheels on zilvia. Follow these simple rules so your future self doesn't hop in a time machine just to slap you for buying spacers. I speak from experience on this matter so don't for one second think I'm pulling this shit out my ass eventhough I sometimes do.

i know that i shouldnt buy rims if i have to buy spacers but some rims dont have the offsets that are on the threads. i mean some rims dont have a lot of offsets to choose from.so i was jsut wondering, if its ok, nd would it snap

I'm just anal about people that don't know how to spell, or are just lazy. If you have a high school diploma or are working towards one then you should be able to spell words like "weaker" and "AND" not "weeker" and "nd". Unless your "A" key is gone.....sorry if I'm a little harsh. Just out of curiosity what rims are you planning on running?

Guys...what's the issue with good, hub centric spacers on a daily driven car...NOTHING.
Spacers are almost a "BPU" thing for VWs, and they don't evert have stories of wheels falling off. If you use a proper spacer - Hub centric and wheel-centric - Like H&R...with new, longer studs...there is NO PROBLEM. My S14 used to be my daily driver...it still sees a lot of street use (~8,000 miles year at least)...plus track time. And I've never had an issue with my 15mm H&R spacers... Now, if you use some generic 1/4" spacers from PepBoys with a universal hole pattern and stock lugs...YES, they may fail and casue a wheel to fall off or something. But high quality spacers are no less safe than no spacer at all. - Brian

i totally agree with you. But he's talking about using the generic spacers from Pepboys. Obviously from his post. If you go the route of longer studs and some serious spacers like 15-30mm, then i'm sure there's no problems (I have previous threads to thank for this revelation). But it just sounds like he's asking about the small 5mm spacers that most people get as a quick fix for fitment issues. i went that route with my old rims that didn't fit once I did my front brake upgrade, really just a band aid for fitment issues, not recommended for a permant fix.
Good point orion....

I don't care what spacers they are. Pepboys, HR etc...
I personally would not run a loose spacer of any thickness for any reason. Loose spacers on the studs are just a problem waiting to happen, IMNSHO, and I just woudn't go there. In the immortal words of Carroll Smith: "Bolts must be used to clamp, _not_ to locate". They greatly increase the likelyhood of breaking a wheelstud because the spacer allows relative movement between the wheel and the hub face, which puts a bending load on the studs. And the thicker the spacer is, the worse the bending loads are. Trying to make simple studs exhibit a decent fatigue life in an environment of bending loads coming from everywhichway (non-hubcentric) is damned hard. Adding in spacers, which increase the leverage and therefore the addded stress from bending, makes it even harder. Sure, there are lots of people out there who run those with great success, may never have any problems, and more power to 'em. But never believe that such a setup exhibits the best possible fatigue life: the studs *are going to fail*, and fail sooner than they should. A setup that worked fine with 200hp and 9" wide tires may well have a lifetime measured in minutes when you drop in a 400hp lump and bolt on the 12" slicks! if you are spending hub centric then why not buy the right wheel? Boyd C can makes wheels, Konigs can make wheels, Works can make different offsets. I wouldn't volunteer to open track a car with spacers. Goodluck. |

^^^ The reason why I run a set (again, centered on the hub and the wheel, so the load is still in the right place, not on the studs) is b/c when I got my coilovers, I needed more room, and was happy with the 7.5" wheels I had.
Later, when turbo power came along, I needed more width...and the spacers actually allowed me to get wheels no one else runs on a 240SX b/c they are 17X9, +40...with my 15mm spacer, they are just right...at +25 effective offset. But all that's not the point... This thread says that spacers are necessarily a bad thing. Not true. If the wheel's load is centered on the hub like with hubcentric wheels (OEM S14 wheels, for example), and you use spacers that are hub and wheel 'centric', then the load is still on the hub...NOT the studs. So it's as if you have no spacer...just as safe. - - - - - Your argument is like saying that plastic hubcentric rings are unsafe b/c they *may* allow movement of the wheel on the hub under load...but no one has ever contributed a wheel failure to plastic hubcentric rings. Now, if the extra leverage on the stud is your argument...that shouldn't be the issue, b/c the load is on the hub, not the studs. - - - - - I follow what you're saying, but it doesn't apply to properly designed hubcentric spacers. - Brian

Hmm.. This is what I understand.
Al is saying spacers will put more bending load and stress on the wheels. But you can also make the argument that running lower offset wheels would also act like installing a spacer. Take for example a stock S14 SE. It has those 16x7 (correct me if I'm wrong) +44 wheels. Then say for example you install a set of 17x9 +15 FN01s on it. Essentially what Al is saying is that, the 17x9 +15 FN01 wheels will put more stress on the wheel hub/spindle/bearings/whatever than the stock 16x7 +44 SE wheels. So by installing +30mm spacers on a 16x7 +44 SE wheel, you're practically installing 17x9 +15 FN01 wheels. The bottom line is? Don't install low offset wheels and keep it within factory specs? Don't install spacers because your car's wheels will fall off? |

This thread is funny. Everyone who has used spacers (correctly) and has had a wheel fall off raise your hand?
anyone? I made my own 17mm spacers out of stock aluminum disks on a drill press and I have run them for a year with no problem whatsoever. |

No one has brought up a defense for bolt on hubcentric/wheelcentris spacers yet, like H&R, or Kics, i really don't think you are going to have an issue there.

while were on the topic, what does everyone think about "kics" spacers?
http://optionimports.com/kiprwhsp.html instead of a loose spacer, it is a polt on spacer with attached studs... im thinking of going 15 in the rear, and 10 in the front..

10mm are not adaptors, just spacers so you'd need to replace stock studs. And if you use anything less then a 20mm adaptor your stock studs are going to protrude past the spacer and into your wheels if they have a full circular backpad.

Alright so today I mounted my 8mm spacers. The lip on the front wheels now sit flush with the fender. However, I'm not crazy like Scott (RBS14) and I'm not super slammed BH-status. I actually have to daily drive my car on some of the worse roads in So. Cal.
I noticed when I mounted 'em, the spacers were not hub or lug centric. SURPRISE SURPRISE! Not big deal right? I was thinking of using some tape and sticking them in place, but I thought the efforts would be futile. I mounted the spacers and reinstalled my wheels. I torqued down my lugs (cheap ass Kyokugens) to 86 lbs. Then I proceeded to drive around my neighborhood trying to notice any shimmying or unusual steering wheel vibrations. Didn't experience any so I went out and bought lunch. Came home, ate lunch and went back outside with my torque wrench to double check the lugs. I then noticed that some of the lugs were somewhat, slightly loose. So I torqued them down and went driving around again. I came back to my car with the torque wrench and tested all my lugs again. Every single lug clicked exactly 86 lbs. Now I just got home from watching Sin City. I drove about 25 miles (mostly freeway) on my wheels w/ the spacers. After I got home, I went ahead and tested my lug nuts. Everything was kosher. 86 lbs on every lug nut. Every couple of days I'm going to check my lug nuts just in case anything happens. I doubt anything should happen. 8mm isn't all that much. I'm also running stock studs and the lug nuts turns freely 5 spins before getting tight. Before torquing it down, it spins a few more times with the wrench. The only problem that makes me a little sketchy about the spacers is the fact that they're not hub centric. I think I should make some hub centric rings next week when I have time. I'll feel more comfortable knowing that my spacers are on straight. I doubt they'll move though, 86 lbs of pressure from 5 different points. The spacers are pretty squashed in there. |

I have heard also that the lug nuts have to be checked from time to time. But its no biggie, as checking air pressure every week and doing the lugnuts at the same time won't be a big deal.
I can't wait for mine to get here. ordered the 5mm ones.
