Vixen Uprights - Dimensions
Discussion
Hello all, think I know the answer but on the basis that if you don't ask then you don't get....
I'm looking to upgrade the rear end on my Vixen V8. I've seen the existing options & while I think either of the more commonly trodden paths would do the job I'm considering engjneering something to suit what I'm after.
Does anyone have an outline dimensioned drawing of the rear upright & hub as used on the Vixen S2?
Either that or does anyone have a spare that I could measure up?
To put a little context behind my thinking :
I'm looking at using something like sierra rear hubs, bearing carriers, stub axles & CV driveshafts. This would allow fitment of rear discs & also maybe even use the sierra diff.
The rear upright would be fabricated in the style of the later TVRs.
An alternative would be to use BMW hardware.
Can anyone help?
If not I'll strip a corner off mine & get measuring!
Thanks,
Stew.

What are you currently running on the car Differential wise I'm looking to upgrade the rear end on my Vixen V8. I've seen the existing options & while I think either of the mkre comminky trodden paths would do the job I'm considering engjneering something to suit what I'm after.

You could look to the kit car industry rather than re-invent the wheel?I'm looking to upgrade the rear end on my Vixen V8. I've seen the existing options & while I think either of the mkre comminky trodden paths would do the job I'm considering engjneering something to suit what I'm after.

Re rear end configurations….It has all been done before.
Also another option,
I re-invented the wheel once upon a time..

Hello all. Car is presently running a Salisbury 4HU (open diff). I'd like to go LSD which is straightforward enough. It is however heavy! Either way I need to swap the diff.
I've looked around & seen that there have been lots of different takes on the theme, my thinking was to do something bolt on using as much oem hardware as possible. Using the ford hardware I think that worst case would be a pair of made to measure driveshafts which are readily available & relatively good value.
The upright can easily be made to suit the existing wishbones & whichever (bolt on) hub/bearing carrier.
I'd like to get away from the sliding joints & UJs if possible as they're all wear points (I do recognise that there is nothing wrong with the setup & it's been used to great success).
Either way I want to do it so that it can have all if the original bits put back on.
Cheers,
Stew

There are Suppliers out there that do up rated Uprights like the original but in better materials and not 40 years Old
David Gerald and Nigel Reubens Can supply.Nigel also has new parts from Quills to Flanges etc as Original but in stronger material Outer Flange is i believe larger on the Tuscan your probably still running the Vixen ones.
Not Cheap but well worth the investment if your planning on using the car as it was intended

Do you have these uprights and are these available for sale? are they machined or as on the photo?
Hi Stew,
Don't know if you are sorted now, but if you fancy a trip from the Midlands to Bristol you are welcome to take measurements from my chassis. The project S3 Vixen I bought 18 months ago, came with a new chassis purchased by him 12 years previously from the man at that time making replacement chassis'for TVR (he was retiring at that time). He had it built to accept a TR6 differential and I was supplied with a differntial ready to fit, so might be what you are after.

Are the measures and drawing of these uprights still needed? I have professionally made drawings for CNC mashinig of the Vixen S1 uprights. I got it made as I was planning to produce uprights for my cars. If these files are no more needed I might be interested where I can get these uprights either mashined or as raw casting.

Hi, I ended up going for fabricated rather than cast (all of the later TVRs used fabricated rear uprights). I have gone a bit on the chunky side in the interests of robustness but amazingly I have added less than 0.5kg of unsprung mass at each rear corner taking into account the switch from drums to discs with alloy calipers.
They are made from a combination of 8mm (all except faceplate) & 10mm (faceplate) T304 stainless which was lasercut then tigged.
Not exactly beautiful but pretty solid! The hubs / bearings & outer joints are Nissan S13 200sx which incidentally has a 4x4.5" PCD plus an easily adapted spigot and 4 bolt fixing flange, bearing is a chunky single piece dual row ball race designed for a much bigger car - it's actually the same bearing as used on the Skyline). I took the liberty of adding 20mm of track each side which allows me to use wheels with a sensible offset. Other than the brakes etc they are a straight bolt on job. I've used 108mm bolt on CVs at the diff end with custom adaptors (I have a Salibury diff) with custom shafts. Seems to work well so far.
Apols for the terrible pics......

Nice Job.
Incidentally the 4.5 PCD on a lot of Japanese cars is a throwback to us winning the war.. We helped them start up car production with the Austin Devon.. Hence a lot of Japanese cars still often use Imperial PCD's and fixings.. even today.. :-)
