5 stud adaptors do work!!! 4x100 to 5x120 pics up!!!

[harry_p]

most of the haters already use 5 studz innit

[Dezzy]

That's spot on mate. I am not running an ABS so I wouldn't need the ring anyway.

[Rav335uk]

Is this the way to redrill then??

Other than that I have thought again about custom hubs. All I need is a new one from somewhere so I can get the ABS ring dimensions correct and have a look at the bearing so I can spec a one which will work as they aren't available separate from the hub. I've thought about these before but dismissed them on the fact that there wouldn't be enough people to justify my time drawing and machining them up.

dont kid yourself Chris, i for one have been thinking for a long time that a direct replacement hub would open up loads of options for us non M3 guys and i would be one of the first on an order list thats for sure. i can see them being a popular item as an alternative to seeking the illusive and expensive M3 suspension.

does your pattern need to be new? i have a used strut with the parts on which i could dissmantle for you. also can we re-use the abs rings as i have had to do this in the past with certain manufacturers, we had to heat the ring to remove and refit but its not too difficult, might help to keep costs down.

Hi Mat, they don't need to be new, it just makes measuring them a much easier and more pleasant task than 10 year old rusty ones that you need to give a good going over with a wire wheel to get anywhere near the original metal.

then when you start to see odd sizes rather than round numbers you begin to wonder if it was by design or just where it has corroded

Dez doesn't need an ABS ring so if his donors don't have one, I'll still need one of those to measure at some point as I need to make sure they are correct for accurate ABS function.



I also had a mega brainfart....I thought I was a genius thinking about an Ali abs ring heated and pressed onto a steel hub, make it a nice tight fit and easy to machine....then slapped myself for realising it relies on a magnetic sensor

[beardymat]

ill have a look at what ive got tomorrow as i think the important surfaces should still be in good condition as they are interference fit so minimal corrosion occurs, obviously this isnt the case for the hub face and centre bore but im sure we can work round these.

i wonder if bmw realised that by making one hub for non abs and abs equipped cars would save them money as in they just pressed a ring onto the abs equipped cars?

Guys, I think it's only fair to let you know that I've been working on a 5 stud hub for quite a while, and it might make it into production.

Then again it might well not ( ), and I'm not doing anything at all with it at the moment as brake stuff is taking up all the R&D time/£ - especially as I didn't realise 300mm.de did those hubs so it's not an exclusive/new market.

I'm just giving you a heads-up as I don't want to suddenly tread on anyone's toes at some point in the future with no prior warning at all (even though what I have in mind is a total re-think).

For the moment/forseeable though it's all yours, I've got brakes on the brain!

[harry_p]

I have heard tha the abs rings come off m3 hubs fairly easily with a puller, hopefully non m3 ones will do the same!

They do.

The ABS trigger ring comes off the hub and the hub is the same as a non ABS one.

replied in the other thread rav but yes that way is the "correct" way of doing it. its not perfect but it applies force in mostly the right way.

its not very nice though and would certainly be somthing id want to hide.

5 stud adaptor hubs would be good but what would you do? base them on modified origionals (tricky) or new billet one offs (spendy).

whats the problem with using the e36 ones on an e30? i thought it was somthing to do with bearings, if so is a bearing not available from an aftermarket (ie non bmw, like skf ect.) suplier that will fit?

also what brakes would these new 5 stud hubs on 4 stud struts use? e36 compact ones? m3 ones?

not trying to be difficult just trying to make helpful sugesstions, as at some time in the future i would consider 16" wheels, 5 stud and bigger brakes.

Personally, if I had to buy a 5 stud wheel, i would use adaptors, as these would be the first choice, and maybe to correct the ET too.
But first choice, in regards to the BBS, there out there in a few guises of the RM's and RS's, but on the dear side of things.

[Dezzy]

For my wheels these would be perfect if they were 20mm not 30mm thick.

this way I could still use standard wheels when and if needed.

RE: The ABS rings:

Think the E30 rings are machined onto the hub aren't they?

Why not do what BMW did for the E36 (and probably other later models than the E30) and have a flat strip made up with the encoder pattern on it. You just wrap it around the hub and weld it in place then, nice and cheap

RE: Making 5 stud rear hubs:

They'd be easy enough if it weren't for the splines. The brooch to make those splines would cost an awful lot of money and when you consider that you can get hubs, bearings and all the little clips and locking bits brand new from BMW for less than £250 all in it's not really worth it I wouldn't have thought.

RE: Making 5 stud front hubs:

Be interested to see if you can find a bearing which slots directly onto the E30 stub axle. I had a breif look a while ago but didn't turn anything useful up and decided that making a giant bolt to hold E36 hubs on was easier and cheaper in the long run, although this does push the hub mounting face out a bit.

[Jozi]

I fitted a new bearing to the front of the car recently and the ABS ring came of the hub, it's just pressed on or left of if not needed. It's wasn't a genuine BMW hub but I doubt that matters. Just a heads up on that.

The ABS trigger ring comes off the hub and the hub is the same as a non ABS one.

[Turbo-Brown]

Will have to double check, but I remember being amazed that the encoder was machined onto the E30 hub I had, and also thinking it was far more logical for it to be made from a flat strip which was curved and then welded on.

Its definately a seperate part which is an interference fit.

[DanThe]

Id rather use this type of spacer than go to the expense of new custom made hubs, would be a fraction of the price IMO

http://forums.vwvortex.com/zerothread?id=4478632

Would be ideal for fitting of E36 type wheels also due to the offset difference

[Dezzy]

They are the ones I linked to Dan. I need them to be no more than 25mm thick though

[Turbo-Brown]

Be interested to see if the manufacturers of these adaptors perform any kind of calculations to see how much of a safety factor is built in.

Even I, with my meagre brain and resources, perform calcs on things like my caliper brackets (and my 5 stud front hub conversion!) to satisfy myself that I'm not definitely gonna die of brake failure or wheel loss

[Jozi]

If the hubs are still manufactured would it not be possible to get undrilled one from them and drill them yourself? Or is there more to it than just getting 5 holes?

[Geeman]

I've just had a set of hub adapters machined up for my Golf, complete with stainless heli-coils placed into the alloy adapters to stop any problems with losing the threads.

Cost me £135 for a set of 4 - 2x20mm and 2x25mm widths... 5x100 - 5x112 stud pattern.

I'm sure they can do 4x100 conversions too...

A small place in South Yorkshire (Driffield)

Will ask if he's up for doing some if there's any interest.

[bss325i]

I dont like the idea of adaptors. I would rather have a propper hub made or convert using propper parts.

More money but the correct way of doing it in my eyes, not a short cut.

[Geeman]

I too felt like that at the start, but having run 3 cars with adapters, I've got no problems with them. They are just the same as having bolt-on spacers...

[bss325i]

I'm not especially keen on spacers either, especially big ones like 10mm+.

I know they can work fine its just a niggly feeling i have about them.

[Baz666]

dont know if this helps
