Wheel spacers
Anyone know much about them, any long term side effects, install problems, etc? I just bought a set of 25mm, now I'm wondering if everything is going to be hip. Any help or suggestion would be appreciated, thanks!

99% of wheel spacers are a BAD IDEA.
On Hyundai's, the weight of the car is NOT carried on the 4 lugs. The 4 lugs just hold the wheel on. The weight of the car is carried by the HUB. That means our cars/wheels are "hubcentric".
Because our cars carry the weight on the hubs. If you install wheel spacers you trasfer the weight of the car from the hub, to the lugs. Our Lugs were not designed to carry the weight of the car. In normal driving on smooth roads in perfect conditions...this will not cause MUCH of a problem. However if you hit a big pot hole or bump at speed, check a curb, or corner to agressivly, you can stress the lugs beyond their ability to cope...and they snap. If they snap...there goes your wheel. Also...just over time. After 1-3 years...the stress on the lugs will weaken them. You go to remove a wheel...and "snap"...the lug comes off with the lug nut.
This is also the reason why Hub Adapters(adapters...not spacers) are needed with most aftermarket wheels. Unless the inside hub of the aftermarket wheel fits the hub on our rotors, all the lugs are carrying the weight.
In Theory, you could buy Hub Spacers that fit our hubs, and that fit your aftermarket wheels, (keeping everything hubcentric), but since you are moving the wheel out from the hub, a significant portion of the wheel's weight is being transfered from the hub to the lug bolts.
25 MM is a fairly significant amount. 25MM spacers move the wheel out by almost an inch. This is going to put quite a load on your lug bolts durring cornering, and severe bump loads.
They would be fine for a car show, curising for a night....but I would not put them on a daily driver...and I would REMOVE THEM for any kind of drag racing or autocrossing or spirited driving.

From what I understand they screw onto your current hub with new bolts of their own. These (H&R?) spacers say they are hubcentric and "say" they improve safty and handling. How could they improve safety if it puts you at more risk? Let me know if you think these are ok.

EDIT:
they actually call it a "Wheel Spacer/Adapter"

I used to have 20mm spacers on my rear stock alloy. no problem at all. had them for about 6 months before I move up to 17" rims with +40 offset. I remember the stock rims had +46 offset. adding the 20mm spacers changed them to +26 offset. Mine had individual bolts, and separate ones for the rims. But because of that, can only fit those rims with captive rotor capable housing, like the stock alloy rims.

Cringe-
That is the correct bolt pattern and hub size for the tibby, so that will keep the wheels semi-hub centric, but since you are moving the wheels nearly an inch out, you will still be stressing the lugs.
H&R does make good products, and those do apear to be quality units. I would put them in the 1% (Remember I said 99% are a bad idea). I would take them off for autocrossing, race track use, or drag racing though.
Uh...those are $150 a PAIR!!!! So you are looking at $300 for all 4 wheels! You might as well buy the correct offset wheels in the first place and save $300!!!!
In regards to the increase saftey....they are refering to moving the offset back out for snow tires or special use tires...not for normal road tires. and I would still buy the proper offset wheels for snow tires rather than spend $300 on spacers.

Spend the $300 on aftermarket wheels and better tires than the stockers.
Well darn it i shouldnt have read this...
I just bought some Motegi MR12 from my Hyundai dealer and he said i would need some spacers but he said i would never feel a thing with them..now i feel screwed..
Im taking them back tomorrow first thing..but can you tell me which wheels have the right offset for a 1998 Hyundai Tiburon? so i dont have to deal with this? sad.gif
thanks

"right" offset?? Stock offset is +42. So if they are +42, they are the "right" offset. However, you will have some room between the wheel and the outside of the fender. (for stock 6" wheels)
If you mean the "Right" offset in that the wheels sit flush with the outside of the fender, then they should be quite a bit lower than +42.
