E30 5 Stud Front Hubs, see last post- mods please lock

[turk]

Hi all,

We have just started the production of our long awaited 5 stud hubs for standard E30 front legs!!!



These are brand new and use oem quality ball bearings and are a great solution to the 5 stud swap 5 x 120 stud pattern.

These will press straight onto your e30 spindle and bolt up as per standard.

If ABS is present on your car the sensor will be repositioned slightly with a spacer included!

Nice and simple and MUCH cheaper then the e30/e36 M3 Leg options!!! There are no sleeves or anything, a simple Bearing & Hub combination, with an oem lock nut and dust shield.

A set of 2 complete hub/bearing assemblies ready to bolt up
will be £449

Now loads of people keep asking about spacing and brakes. So here the low down

The hub has been custom designed to offer identical geometry to the e30 as standard!!! There fore you have a wider choice of wheels an callipers that will work.

You can use standard Callipers if you wish, but an appropriate brake disc may be required.

The same goes for the calliper, You can bolt up most BMW callipers and discs with little work.

We also offer various Calliper mount brackets for the E36 m3, e46 330i, and the e34 540i callipers. BMW being the way they are, many other callipers are likely to bolt straight up too!

Our favourite so far is the 315mm E36 M3 disc and E38 4 Pot Brembos

If you are using e36 compact, E30 M3 or Z3m trailing arms your standard e30 abs rings will press straight onto our hub. If however you are running a different rear/abs setup we can make an ABS ring to match the tooth count you need.

The product will be supplied with a 12 month warranty!

Soon to follow, Complete Hub/Bearing kit for the E30 5 stud REAR Wheels.

These will be applicable to both standard E30's AND E30 M3's

We are currently going through the TUV Approval process hoping for approval making sales in Europe possible, and hopefully offering UK customers a bit of piece of mind!

Saw this on Facebook earlier, surprised it hasn't been done before. Not something I'm looking into but something I thought about was, are the bearings replacable or would you need to buy a new hub?

[jmc330i]

Is there a change in the front track width or do the hubs sit in the same place as the originals?

[turk]

The bearings are integral to the hub like standard. There are 2 rows of balls held by the hardened inner walls of the hub. The hub will sit 2 - 3mm further out compared to standard.

But in special cases we can remake the the hub 'face' to sit further back/forward. These would be one offs, but possible.

[harry_p]

Does sound like a superb idea, and surprised its not been done sooner.

What about disks? Do you get standard ones or is there an off the shelf 5x120 disk which will work with the standard callipers?

Also, are you planing a rear hub? I know m3 ones were available and I believe press into standard bearings, but not sure how much they are, or how many BMW have left.

A straight swap front hub and 318ti compact rear end is going to end up with a wider rear track, which is fine for looks but more likely to give fitment issues.

[jmc330i]

The hub will sit 2 - 3mm further out compared to standard.

Will the standard brakes (obviously redrilled discs) fit ok with the hub sitting further out or will the caliper need spacing as well?

[turk]

So far I have been mainly working with e36 & e46 m3 discs. I have always had big brakes kits in our mock ups so far, like readily available brembos.

A very good question re the callipers. Based on the spacing if the calliper cannot accommodate the slight difference with the piston then the calliper may need spacing.

I will look into it ASAP and feed back here.

Thanks for the comments and questions.

It was looked into, but a decent/safe design was difficult to find. Be good to see the solution turk has found

A straight swap front hub and 318ti compact rear end is going to end up with a wider rear track, which is fine for looks but more likely to give fitment issues.

I think E36 offset wheels are needed with the ti rear end, so maybe they could be used on the front depending on the final offset these hubs give.

Using the E30 M3 rear hubs also gives a slightly wider rear track - M3 track width.

[DanThe]

Looking forward to seeing how this goes together

Only other solution I know of it the e30.de sleeve and bearing

[turk]

No sleeving ! I would never want a sleeved hub on my own car so couldn't justify selling one to a customer.

We are basically remaking a 5 stud hub to fit straight to the e30 leg.

Cheers.

I'll be watching this myself as it's something i'd like to do in the new year,

as someone said before just waiting to see/find out the rear hubs as it's a bit daft to have 5 stud front & 4 stud rear as I kit similar to the front would make more sense & be easier than trying to track down e36 Ti trailing arms or m3 rear hubs.

waiting for the updates.

[steve_k]

Just had a look & it appears that m3 rear hub's & bearings are still available, but couldn't find a price.

[jmc330i]

I never liked the sleeve idea, although has it been approved by the bods in Germany so e30.de can sell them? Either way, as above its not something I'd want on my car.

This could be the solution I'm looking for though for my touring, providing (as daft as it sounds) I can keep the standard brakes.

[jmc330i]

Just had a look & it appears that m3 rear hub's & bearings are still available, but couldn't find a price.

I had a quote from Cotswolds on here - £280 for the pair.

Not sure what rear brake solution could be used though, other than E30 M3.

thats not to bad suppose,

thing is, would e36 Ti (compact) rear hubs fit straight on to an E30? As the prices i've seen are very cheap compared to e30 m3 item's.

I believe they do, either that or complete arm with brakes, but it will mean running E36 offset wheels. Turks 5 stud hub should bring the front close to E30 M3 specs I think, so you would need around 20mm spacers up front to run E36 offset wheels - I think I've got that right! Or run mixed offset wheels

The hubs won't, but the whole arms complete with disks, callipers etc does, but then you run into issues with the abs as you'd be running e30 spec rings on the front and e36 on the rear.

Compact stuff is certainly a lot cheaper though, you can pick up complete running and mot'd 318tis for what a decent e30 m3 rear end would cost!

I did work out the difference in track a while ago, from memory it's 15 or 20mm per side extra using the e36 rear arms.

However, I don't think it would be that big an issue as standard e30s always look narrower at the back, but could cause clearance issues if the whole point of the conversion is to run a nice deep dish set of 5 series wheels.

[baboon5151]

hi would these be much difference to e30 m3 set up as i have everything to change the rear of my sport to m3 set up.for the front i will be using brembo 4pot big brake set up & coilovers all round.cheers

[staley_turbo]

I heard the 1 series rear hub fits?

Great idea with these kits. Would buy one if I thought there where any benefits.

[buster]

cant you just re drill the hubs for 5x100 (because that'll fit) , then put proper h+r or the like adapters from 5x100 to 5x120.

[oldroydsr4]

Good idea but if the only reason you want 5stud is for looks, by the time you have sorted the front hubs at £400, rear m3 hubs at £280 and then sorted brakes etc you are fast approach image split wheel money

Add to this the fact that the bearing can't be replaced separately, then you have a vry expensive repair.


I personally think it needs further thought or a whole package kit.

This was my first thought when I saw the title of the thread.
Most people go 5-stud as a requirement for getting bigger brakes, because nothing will fit (properly) to E30 Struts.

[Demlotcrew]

Looking forward to some photos, I won't be buying them but some sick deviants might.

This!

What if you clout a big pot hole? Another £400 to replace a fooked wheel bearing.

Sod that!

This and barrys comment is the issue with custom hubs, I did do some research and quickly abandoned custom hubs despite having a working design as the cost was simply not worth the time, you were either left making peanuts or selling them for silly money.

I don't know if I will make any kits or not but I do have a prototype "kit" which gives matched offsets, full locknut thread engagement and sufficient nut locking but I doubt I will sell too many as I don't want the risks (and insurance costs) involved with producing suspension components.
I do however have a fucking animal of a test driver for the current kit so I will do a post with how it goes, the guys a weapon, he could break a steel girder if left to it.

[Demlotcrew]

As pointed out by RedCar, five stud hubs have been available for quite a while from German suppliers. Not sure on their costs.

Andrew

is that the kit from 300mm.de? The one that uses a sleeve between the stub axle & the lock nut??

been around a while but has anybody used it??

[bss325i]

I dont see what the problem with using a sleeve is.

As long as its a tight fit and the nut has full thread engagement whats the problem?

[HairyScreech]

~1000 euros for a kit without brakes, so i doubt anyone has used them over here, again the costs just don't add up.
At that price your back into e30m3 bits price range which someone spending that kind of cash will go for over a conversion kit anyday of the week.

[jmc330i]

I've not seen the German kits, but the 'sleeve' kits that were looked at on here didn't have a full thread engagement, that's the reason they weren't developed any further as far as I remember.

[HairyScreech]

This is the big deal breaker, there is nothing wrong with a sleeve kit provided it is done right, a sleeved hub with the sleeve end in the correct place done in the right way will be as strong as the e30 hub/shaft combo, done wrong it could cause stress concentration issues.
However none of the kits currently available have solved the thread engagement and locking issue.
I think/hope i have and for about £10 per pair of locks but time and testing will tell.

Brakes are then the next issue......

[b12rlw]

I've often wondered about this one. Surely there are bearings out there sized to fit? I've still to have a look at the e30 spindle and an e36 hub to see what's needed though.

[Demlotcrew]

I don't see any sleeves with the 300mm kit and every product of his is TUV approved so no issues with safety.

[buster]

There's plenty of room on front and rear hubs to drill and tap the hub for 5x100. Then re drill the extra holes into the disks. Then you could still use 4 stud ( for track days etc ) and using a 5x100 to 5x120 adapter ( h+r make some ) bolt on e36/46 5 stud wheels. Even if you fitted the Audi tt brakes you' d only have to bore 1mm from the centre and fit it ( or drill the extra holes so you can use the 4 stud wheels).

[HairyScreech]

The bearings actually run on the metal of the hub, so the hub acts as the outer race for the two pairs of opposed angular contact bearings.
Been there done that, if only it were that simple.

I don't see any sleeves with the 300mm kit and every product of his is TUV approved so no issues with safety.

I could be wrong but i think they are already in the hubs in the pictures on the site.
Certainly looks to me like there is something inside the e36/46 hubs there.



Looks to me like a sleeve as the e36/46 bearing should be flat where the nut touches, that looks stepped?

The stock e30 hub is to small for the 5x120 pattern to fit in safely.
The outer of the e30 hub is only something like 130mm!
