Law of levers.

Where the formula is force times distance from fulcrum / pivot.

The original wheel with no spacer is say 1mm from the fulcrum times force (one quarter of car weight or 250kg, for example)
The moment force is thus 250kg/mm (in reality the distance is a lot smaller than 1mm but lets just run with this)

Move this out a further 13mm and you get 13 x 250 = 3250kg/mm of moment force (if this is the correct term - my physics is rusty from high school, but I remember the formulae)

This is the static load on the hub and studs alone. You must also incorporate force from the engine, cornering force and braking force.

The bearings are only manufactured to OEM tolerances of force (movement), which would be only tolerant of slightly higher limits. Thus increasing the likelihood of bearing and stud failure.

They're illegal for a reason.


But I don't expect you to understand this Jovan.

So on trucks with a double rim that pivot almost 5cm each way from the hub bearings and studs fail?

Have you ever seen a failed stud or a wheel bearing Alex? and changed one your self packed it in tightened it and reassembled the hub to OEM specs?

A whole lot of people talk and research the internet....

And a lot of people didn't do Physics at high school and uni

Trucks with a double rims are on leaf springs and solid axles, so the law of levers is different, and therefore, does not apply.

Subarus aren't leaf sprung or have solid axles, last time I checked... But are MacPherson strut (Gen3 onwards have multilink rear) which all apply to the laws of leverage.




Failed wheel stud? Personally myself? No. On someone else's car? Yes. That Subaru MY series to the left of the photo had snapped a few, as he was running Landcruiser rims, which again, had a much bigger offset (and width) of wheels... And snapped a couple whilst offroading. (Sheer lateral forces)

Failed bearings? Plenty, with my old Subaru, with incorrect offset wheels. In fact, it's a common problem with the older Subarus (MY and L series) running the Sunraysier rims with big tyres. The rims run a massively different offset, and they stick out beyond the front and rear guards, as they were originally designed for the Peugeot 504, and not the early Subaru, but ended up being popular with the Suby modders, as it allowed a more significant stance, and because they were the only readily available 14 inch rim with a 4x140 stud pattern, they allowed a much better tyre choice (mostly offroading tyre treads).


Yeah, that's mine, to the right.

And before you even ask... They were sealed bearings. The elements had little to do with the failure, rather than, incorrect offset (which wheel spacers inevitably cause) and significantly increased wheel mass.

I know... Because I changed them myself. Actually I used to change the front ones every 12 months. The rears lasted a little longer but were also prone to failing.

Would there be anything else? Any more negative comments? Sulking? Poorly veiled statements with hidden meanings?

Because we're not getting any logical or any mutually beneficial discussion from you.

[Jovi]

Sealed to a degree, now the other flips side Alex is where did you take that car 4WDing? So the elements did stuff them up. Nothing is 100% sealed. And wheel bearings can fail for many different reasons common is over tighten, elements and people like you thinking they can dump them into mud and think nothing will happen.(thats why you changed them every 12 months not because the offset of the wheels) And yes your L series is just a car not bullet proof 4wd, even the l'cruisers, land rovers etc. That are meant to, be dumped into mud and other crap still fail like any ordinary passenger car.

Now when you do it everyday and see it all (and before you say you seen it) trust me you haven't seen ****. Because most of what you and 90% of the forum users consider changing wheels a sway bars and oil (things like that) is working on a car, i'm sorry but you and them don't know a single thing. There is a few guys on here that do know what they are talking about and i take my hat of to them and (you Alex are not one of those people....You can say you modded cars done this seen that at the end of the day you paid someone else to do everything to your car....

You're an auto electrician, aren't you?

So tell me, how is it that you see this every day?


Your arrogance is truly amazing. Especially for someone like you.

[Jovi]

I am also a Mechanic and have a pink slip licence and working to get a blue one too.Also 8 years working on cars everyday. So yes Alex my arrogance is truly amazing. So run along and be a Nurse

When are you putting the new springs in dale?

Haha shutdown, yeah Dale sorry thought you were talking Buddyclub not BC Racing, sounds good anyway, and looking forward to seeing them go in.

[2003rx]

Well im hopefully getting them this friday, and it will probobly take me most of the weeekend so hopefully ill update this thread within about a week !!

Make sure you buy spring compressors, and should take you about an hour to change the springs over. But all up half a day to do all for if your not using air tools.

[Alex]

Congratulations.

[SAV84C]

Here we go again! *sits back with some popcorn*

[2003rx]

Hahahahah, yeah ive been told a few times about the spring compressors, where abouts do you get them and are they easy to use ??

[BigWillieStyles]

Good mods. Can we have some pics of how the car sits with the spacers?.

Repco, Scott's auto one, you can borrow my set. just compress them equally and don't rush..

Yeah, these are prob the best i can really get out of my camera

No idea mate, are the bolt for the mounts tightened properly? Did you use the grease etc supplied? After installing mine, it had Sweet F all movement and didn't make any noise..

So i FINALLY found the problem. Under hard right cornering the sway bar would actually move just far enough that it scraped the side of the exhaust shield. This was found after a lot of inspection and a noticable dent was in the shield. So i cut out about a 3cm by 2cm section of the shield, and problem solved !!

Just did a resonectomy with some parts i ordered from the USA.

2 x Black Silicone Elbow Joints
1 x 2ft Aluminium Pipe
Total Cost $60..oh yeah

Firstly, i removed all the crap that was already in there.

I then went to town on the parts as they had to be cut to size in order to get a straight flow

Lastly i put it all together and tightened the hose clamps

I think it looks great and the parts are soooo cheap for the US

That looks awesome mate. Did it make any difference, i.e. noise, power?

Thats the price all intake pipes should be. I cant understand how companies can charge 300 dollars for a CAI like the Hyperflow ones.
