Default Aggressive offset and bearings

Can we get a thread going and sticky it regarding flush/aggressive offset wheels and bearings? I tried to search this subject but most of the threads that come up are just people asking if they can use a certain offset and yada yada yada.

I'm not going to lie, I used to be on the bandwagon about running low offset wheels and ruining your bearings but after seeing so many people running this set-up, I have yet to actually read bearings getting damaged.

So for you owners that have low offset/aggressive wheels fitment, can you chime in with the dimensions of the wheels, how long you've been running them and if you are STi or WRX (to see if there is a difference between the bearings) and how your bearings are performing to date?

Chimes in about what? If you've seen information on this subject please show me as I've tried to look it up but come up with only what I've already mentioned.

This low offset craze has only been running around for what a year? Unless they're putting 20k on the odometer it's gonna be a bit before the bearing failures start popping up. Plus, what's the chances that they're going to post that they had a bearing failure

Understandable but the fact is when the craze first started, everyone was adamant that the bearings would fail and to an extent made it sound like it wouldn't take long. Even so, people who may not drive the cars as often must be driving at least in some what metropolitan areas where factors such as potholes and what not affect the wear with that type of set-up no?

Well that's why I started this thread. So that we can have a consolidated thread of actual facts from people that run this. Because we have such a divided opinion about this and I think eliminating bandwagon with actual facts is better then having people spew just things that they read or hear.

You want statistics to disprove facts of physics. If wheel bearings last 100k+ for many people is 50k failures something you would expect? How many of these people are going to keep the car with low offsets for 50k? How many do you expect to say "yup, my bearings died". Nobody said they were going to fail within a few months, or a few thousand miles, but they WILL fail faster than a car running a stock offset.

Yes I understand that but I just think that having real life accounts of how this set-up holds up is beneficial to our community. If you don't agree then obviously that's your opinion and you're entitled to it.

But the point is right now we don't know how long this type of setup lasts before one might start to experience issues. I just started this thread to keep an account of it. If the mods decide that it's pointless then let them delete this thread, it's fine with me.

I can just as easily go and pm members of this setup and ask them how their car(s) are fairing. I just assumed that there were others like me that in their heads asked the same question but were too afraid to ask because of the fear of getting ridiculed on a public forum.

The bottom line is that wheel bearings are "wear" items. Like some others have said, chances are you won't get the life out of a bearing on a +30 offset than you would with a +52. That said, it's not going to be as drastic as 50% less lifespan. I guarantee that a track car with stock offset will put more pressure on their bearings than a daily driven hellaflush. A lot of it falls down to one's driving style. Take lot of fast turns? You're putting added pressure on the bearing regardless of offset. One also needs to consider that today's wheel bearings are built well, and in the case of our cars, overbuilt. They can take a few more mm's.

When I had my 02' WRX wagon, I rolled +48 for years. Fast forward to around 30,000 miles, and the car was at the dealer getting warranty work done on the bearings. Sometimes it's the luck of the draw. Like WRX trannies, some blow after a few launches, while others last 100,000 miles on a GT30 turbo.

I think thats the best answer Ive heard for a while^

Im running 18x9.5 +40 et with a 10mm front spacer
Ive been on this setup since march, on 06 sti hubs. No problems yet. I havent tracked on them yet, and the hubs are used.

me...

04 STI

been rolling around on 25mm adapters for over a year (making most of my wheels +21-23)

then switched off to random low offset wheels in the +30-35 range

I drive my car hard, and I do road trips to Vegas and SF from LA often.

I have 54k+ miles right now. The bearings are a wear item as stated. I know some people only get 80k on them. Some people get more or less. Mine show no signs or wear or anything right now. If I get another 10-20k on them I will be happy. If the tradeoff is only 10k miles or so I think that's a very fair tradeoff for being able to have a clean looking car.

It goes the same for the motor. If you are producing 400whp and drive it equally as hard as a stock setup it will go out faster with 400whp.

same as for a clutch, brakes, struts, etc etc

modding is fun... and wearing out items just gives you the opportunity to upgrade and make it better.

hypa - 05+ STi bearings are designed well, but all WRX models and 04 STi models have much less stout bearings. These will fail sooner and with less stress than the 05+ design even on stock offset wheels.

As for track vehicles, the question then becomes is it a heat related increase in failure rates or offset related. I would hazard a guess to point more towards the former rather than later.

I personally don't care about the life of the wheel bearings, or the physics involved (newton). The completely overlooked issue with the wide wheel and the offset that makes it "flush" is found in Geometry. You simply reach a point where the scrub radius can no longer be corrected because the camber adjustments needed to alter the steering axis angle are so ridiculous that the tires cannot perform. Thus the car cannot perform. I am glad that it gets overlooked because that gives folks like me an edge. A properly sorted suspension (calculated, diagramed, and corrected) with components that actually perform in harmony will turn the same lap times with considerably less power. It is simple math, but the " I want it to look like that" crowd obviously don't utilize it. I am not against people doing what they want, just pointing out that for so much talk about performance it seems odd to act to the contrary. You wouldn't need to worry about that extra 100+ whp if you actually sorted out your car. Truth be told most people aren't experienced enough with performance driving (need for speed doesn't count) to actually know the difference. It is more than two cents and wanted or not I tossed it into the pot like everyone else.

which is why it is SO ****ING IMPORTANT TO FILTER WHAT IS POSTED

so that the poor stupid bastards that are reading this **** dont get to far ahead of themselves

It is irresponsible to recommend 'excessive' options based on "I do it so it must be ok for everybody to do it".
This mentality(or lack of ) is responsible for MUCH of the that happens on this board and
we all can see that LESS ****ING CONFUSION WOULD BE A GREAT THING

UFO - excellent point about the scrub radius and camber issues that come about from making these wheels fit. It's a difference between function and form...unfortunately most now only care about the form

FWIW, I run 17x7 47 offset with 225x17 semi slicks and15mm spacers (to clear the front Brembos). Camber -3 deg track setting on front, -2 deg Road on front. Rears stay on -2 deg.

I would have run 20 odd track sessions so far over the last 2 years at 15 laps per session - 3.5km tight track - so about 1000km to date.

Bearings just starting to make a low wrrrrrrr now but no big deal. Will probaly change out early 2009.

For me, I went this way to get more front grip and consequent less understeer. The bigger rollbar on the rear also helps. I love the way this car works on the track for me. Yes bearing are maintenance items and replacement every 2-3 yrs is ok by me.

Love this thread.
