Default Offset Question.

This may have been covered before but I have tried searching. Anyways I am trying to figure out what happens if you run low offsets on the 04 STi Hubs and setup 5x100. I was talking to a friend who said running a 35 would shred my diff and cause countless problems. However I have seen people run +35 before.. Can someone explain or point me to the direction of what will happen if I put +35 wheels on my car. I am not tracking the car and am not planning to either so it won't be driven hard if that makes any sense.

A low offset, like +35, should not have any effect on the diffs. All 3 of them. It is harder on the wheel bearings. Just like you use a longer wrench for more torque on a nut the shalow offset puts more of an over turning moment on the bearings running straight down the road.

how long would you suspect the bearings to be able to handle the torque moment like this? It would obviously not be an instant thing. Is there anything you can do to beefy up or increase the strength of the bearings??

How long is the $64,000 question. Bearing life is based on statistics. They have something called the B10 life. That's number of revolutions when 10% of the population will fail at a give load. The different offset increases the load, did you get a low life B10 bearing, or a B90 that will live forever? This is why no one in their right mind recommends straying too far from the design specs and few have any sympathy if a bearing goes bad. At the track bearing are considered a wear item and while we complain it's not unexpected.

The only way to beef things up is to redesign the hub for different steel bearings. Subaru did that with the >05 STi. It's ~$1000 in parts from 6gunracing to convert not using the '05-'07 STi front struts.

Lot's of threads on this conversion, and there is a ceramic bearing thread kicking around right now, but those would be $$$$$. (You can get a little better life when installing the stock bearings with better grease. How much of an improvement?)

That is really helpful! Thanks for the help Web Foot. I am going to search on the 05 hub swap. Do you think it is worth the money to upgrade or would replacing bearings suffice?

If you are not tracking the car it isn't worth the money to upgrade it the >05 STi parts.

If you don't get a B10 bearing, or worse, there is such a thing as a B1 and it is statistics, you could get 100,000 miles out of your bearings, just don't be suprised if you don't.

I've got 52,000 miles on mine and have been around PIR a few times at speed. No problems yet, but I won't cry if a bearing does go bad. Curse yes, but not cry.

it really does make the car drive and feel different

id try to stay with a +40 or higher...fewer problems overall

putting the wrong wheels on a car just to look koo is dumb

I know a lot of people hate the "flush" look, but I honestly think it completes the whole look of the car. That is my opinion. Is there a way to achieve the look without offset? Or is that pretty much the only way?

I hate to admit it but, I have 160K on my stock bearings. I drive mostly freeway with a dose of twisty roads everyday for my commute to work. Now that I've said that, I'm expecting them to finally fail. The stickier the tire, the wider the wheel, the more loads are transferred to the car which increases wear. Keep that in mind if your car is your sole mode of transportation.

Properly wide wheels with a correct offset will fill the wheel. But, if you're doing this just for looks don't worry about your bearings. They'll fail faster but as long as you look cool

I am not only doing it to look cool. That is why I am asking all these questions. ...

I am looking for some help. I am not looking for some lame a** comments that you can LOL about, give yourself a pat on the back, and smile to yourself about how clever you are in front of your computer screen.

I am trying to figure out if offset is the only way to get this look.

i don't understand.. in any case, most ppl do this to look "cool" though

even with a 8 or 8.5in wheel, proper offset and correct sizing tires, that can make any subaru look pretty aggressive

Um, that look is not for anything but LOOKS unless you're running a meaty ass tire/wheel combo, can't properly clear suspension while maintaining correct camber levels etc... Are you interested in the looks of the car or the performance of the car? Because, as already stated they don't go hand and hand many times.

OP has said nothing about performance in this thread. He simply likes the look. Again, it seems as if he is not interested in the performance aspect (or the detraction) of running the wrong wheels.

You didn't bother to read the post I quoted BY the OP that it wasn't about the looks. It's also called calling him out

You guys love to have a pissing match!

Why not offer up some constructive suggestions instead?

Admission, a 18 X 8.5 wheel with +44 offset will pretty well fill out your wheel well.

I may have been given all the information I asked for, but he actually suggested something more suiting, or other options... Yeah I learned that +35 will affect bearings and is only for the "cool" look, yada yada.... but nobody else offered opinions or ideas that would achieve this look without sacrificing performance. Maybe I was a bit ambiguous on what I was asking, sorry that everyone doesn't know as much as you guys.

Well, nobody gave you specifics because it's going to be completely dependent on offset, wheel design, tire width, camber, suspension drop, whether you're willing to modify fenders etc...

It is not a simple answer.

before i forgot, a member by the name of timeless has some 18x8.5 for sale from his sti with 255s i believe.. you can ask him for offset info and whatever it took for his wheels to fit.. he's not part of the "flush" crowd.. he's smart, so mssg him if a wheel with those dimensions would suit your needs

If the offset is in the low 40's, they would be a great wheel to run, without making major modifications to the rear fenders. Plus they would fill the fenderwells quite nicely.

The guys running 18x9.5 really deserve some respect. That takes a hell of a lot of work to fit.
