I want to use Wilwood hubs in a car design I have and I was wondering what uprights can you use for this (want upper and lower wishbones). Anything off the shelf?

Have you looked at the Raceleda alloy uprights? Not cheap, but may be compatible, modifiy-able!

see here Rally Design website

a very good idea Nick205!!

Would be very easy to turn/get turned, some different spindles for those uprights to suit your hubs.

If I did by the upright package from raceleda I guess I would need new stub axles??? Would I need anything else?
What about rear uprights?

Might help us to help you more if we new what layout the car is ? what its for ? , what drive train/donor ? and if it is for road or track ?

I got a colleague to design a car and I am now looking at suspension and chassis design - car is for track and road use and will use a 9.2 litre V8 and a Porsche transaxle (mid-engined), no traction control only power steering. Looking at using a spaceframe with upper and lower wishbones front and rear. I am a little stuck on what hubs and uprights to use, I was looking at Wilwood as I was going to use their brakes but was a bit confused as to the bits required for the set up as I couldn't find any info. I think I may use what people are putting into a GT40 replica, have been in touch with raceleda and they have front and rear alloy uprights which are used by the GT40 crowd and so they seem most likely now.

Was it designed or styled? If it was designed, the suspension should be part of it.

How about Porsche 928 rear uprights? That way bearing fit is guaranteed, the axles can be used as-is... there's a lot less work to do if they can be used.


NS Dev - 3/2/06 at 04:00 PM

Interesting point KB, do you know if 928 driveshafts have the same inner end flanges as 911 ones??

If they do then what you say may indeed be a very easy option!! (I assume he's using a 911 transaxle turned upside down and back to front)


kb58 - 3/2/06 at 07:32 PM

No I don't know about them being the same, it just seemed more efficient to start with that. If one end of the driveshaft assembly had to be modified, it's still easier then starting from scratch. That's assuming the 928 rear upright isn't some huge heavy monster.

Now that you mention it, I wonder if they do indeed plug right together.

The Porsche hubs will be for wheels with a 65mm offset and a PCD of 5 studs/130mm. That's a wierd wheel spec that will restrict you to Porshe designs unless you have a new hub made up to fit your uprights.

Raceleda are direct copies, in terms of geometry, of old ford designs. That's great if you want to replace an old Ford bit and is also great if you want to have a big choice of wheels and brake bits but it restricts you to very large scrub radii. The Escort Raceleda design, assuming I've got the geometry from their drawings right, has 84mm from the tyre contact pivot point to the wheel flange face. So with a 38mm offset you'll get 46mm scrub.

For Comparison the Porsche 928 has negative scrub of 10mm or 16mm depending on the model, the Elise has 10.5mm positive, the MX5 has zero and most BMWs have a small positive scrub (one model being quoted at 7mm positive).

9 litres is a lot of engine --- I think I would be look at Jaguar XJ front uprights -- bespoke Jag brake setups are available.


bertquock - 4/2/06 at 11:51 AM

Got any links to sites with the Jag bits?
I wanted to use the front and rear assemblies used in the oval track cars as they are using large high torque egines


britishtrident - 4/2/06 at 02:08 PM

For Jag specialists usually a scan through the up market classic car mags will turn up something with a web address, I don't have one handy --- not sure what pcd jag wheel hubs are, I suspect it might be 5 on 4.5".

Use pinto/mustang.II uprights (dirt cheap on ebay *all* the time), w/ the wilwood 2129 hub and brake kit. The only issue is that the book bones need to be changed a bit to match the uprights. There is a thread on it somewhere on here.

The wilwood 2129 can be got for $652...here is an example:

Also, when you talk large scrub, i assume you are talking the raceleda cortina stuff. That is because the cortina uprights have a 4.8deg kpi. But, raceleda also have a granada based upright, which has 7-8deg kpi. That combined w/ the escort hubs gives a pretty good scrub.


smdl - 10/3/06 at 03:46 AM

I see on the Raceleda website that they have hubs in Cortina, Escort and Granada, but they only show "Universal" uprights. I can see how the different hubs might impact scrub, but the KPI must be controlled by the upright, correct?

If they only have one upright, then I would think that the KPI will always be the same.

Sorry if this seems daft - I'm still learning and may be missing something.
