Custom 5 stud conversion hubs, 5x114.3PCD

**9000rpm** · 24-09-2007, 06:58 PM

I'm looking to get a batch of 5 stud conversion hubs made.

To fit onto the common Celica/Corona/Cressida stubs and use standard bearings.

I'm sure there would be a few interested but I need to know a few things first....

1. How should I set up the disc mounting? bolt on rear or slip over type?

2. What discs should it suit? AU? BA? R32? R33?

3. Should I make it 67mm where the wheel locates on the hub so it matches the F and G series axles?

4. What would be the best hub to copy as far as disc mounting offsets go?

Any other thoughts?

1. Slip over.
2. BA.
3. Yes.
4. MX83.

Disk over hat.

BA & R3x, both are 5x114.3, so I'd design around the one that has the smaller hat ID.

I'd be tempeted to make it make it to stock cressida/corona/etc ad supply spacer rings to suit depending on the persons application...or 68mm and the person can get it machined down to suit...(Keeps options open)

In regards to disk offset, BA is prbly better as it gives more caliper->wheel clearance. But this really isn't an important point I don't think, if you design around BA in this regard then there is no reason the person can't use R3x disks (Keeps options open

)

In regards to total wheel offset I'd go for something that allows 8" wide rims with ~ +35offset to fit

(taking into aacount the offset added by the disk over hub mounting

)

Tough call.

My thoughts.

1) Disc over

2) Skyline (BA will still fit if its made to suit Skyline, but not the opposite)

3) BA is 72.1mm from memory, Skyline is 68mm, Rest of Toyota is 60/60.1mm. As Wilbo said, make it the largest, and people can machine down to their requirements.

4) Tough tough call here. If you make it to suit FWD style offset like MX83, then those who put these on older cars will have to get severely mismatched offset rims to keep the car legal. Personally I think you need to make them to suit the same as the car they are going on.

That all said, I'm not ever going to buy any, so my point of view can be ignored

Do what i did and save yourself alot of money!

Go to the wreckers and get a pair of falcon hubs (i think they're all the same from early 90's to now, or just get au/ba ones to be safe). Have sleeves made up by a machine shop to be an interferance fit and heat shrunk onto the original stub axles. These act as axle stiffners also, with the added bonus of being able to utilise the HUGE bearings that come in these hubs. Then get BA rotors that fit straight on and you're half way there! Here's some pics of my sleeves and the thick washers i had made up also. The offset i ended up with is about a 38+ as i have a set of 16x8 wheels with 38+ offset and they sit perfectly in the gaurds, miss the strut by about 3mm!! I love it when shit works!!!

I have thought about something like that.

I thought the Falcon bearings werent that big thats why they always have problems with them?

Christ!!!

If the bearings were any bigger they'd also be able to be used in my old man's Kenworth!!!! I doubt they'd ever play havoc, they are HUGE!!! See the size of the washer i had made up?!? Thats the OD of the bearings, the shaft size on the sleeve is the ID.

Have you spoken to Hopper Stoppers?
I'm pretty sure they already have these off-the-shelf, already engineered, etc etc.

there's also a mob on eBay who sell a lot of ford/holden brake upgrade kits - i contacted them about hubs a while back and they said sell hubs only for a reasonable price (sorry, cant provide link, ebay blocked at work). Thy would use the stock bearings so if you wanted a more robust bearing then another stub axle/strut donor would be required and if you do that then the hub issue becomes academic.

medwin: your kit sounds interesting ... any idea on how much to make/fit the sleeves? and could you use a key to hold them in place rather than heat+schrunk.

The sleeves were about $250 i think, obviously in mass production the price per unit would come down. Yes there is about 2 inches worth of sleeve that the hub goes no where near and would be able to be used to thread some sort of locking bolt into the original stub axle.
