Rear uprights
Hello all, This question might have been here before but its not showing up using the search function..
Im after a upright to use at the rear of my build, Id like to be able to run 4*100 wheels (vauxhall/opel, ford, renault et all, but can redrill for
this anyway) but Im going for a classic double wishbone layout independant rear suspension.
Now here's where I get picky, I dont want to use a upright with a machined adaptor to replace a strut as Ill be beating on the car and I dont
like the thought of one coming loose, I just want vanilla out the factory top and bottom suspension pickup points. And it must lend itself to disc
brakes too. I also dont fancy making my own, as there will be a lot of stress on that at 150+ (wishfull thinking) and its going to have to deal with
the power of a tuned v8 going through it..
So far Ive only seen uber expensive small production run uprights aimed at lambo kitcars and the like, and Id rather not spend more on the uprights
than the entire car has cost so far. Im not after 10 quid from the scrappy cheap, just under my rear suspension budget of around 300 pounds... So, I
throw the question to the wide experience of people here, any suggestions as to a suitable donor?

Champagne taste on a beer budget, eh! 
Sounds like making your own is the only way to go.
I haven't followed your build, do you weld? If your welding is good enough for the rest of the car, it'll be good enough for the rear
uprights.
They're simplicity itself to make (just make the patterns from cardboard and have a dry run) and you get to choose which callipers you want.
The pay isn't very good , but the work's hard.

material
I forgot, it'd be also quite nice if they were made from aluminium alloy (reducing unsprung weight and all that), and whilst I have the kit and
competance for steel, I stick to manifolds and non structural stuff for ally...
I dont want much do I

Would something like the uprights fabricated for the MK Indy not do the job?
What diff/driveshaft/hub set-up are you using as this will probably determine the wheel fitment and caliper choice?

Yeah, they're ali and take ford sierra hubs, escort front discs and sierra calipers. This means that you can get spares very easily and you can
get 2-pot rear calipers from wilwood for them. It also means you can fit any 13" wheels.

Honda uses 4x100, and they have millions of aftermarket products that are incredibly strong.

The westfield ones look just the job and fit in with making my life easier in a lot of other ways too. Ill give westfield a ring tommorow, and see
what they cost as theyre not on their website..
Car so far is based on a rover v8, which is bolted on via an adaptor plate to a renault transaxle, I know for sure that granada->renault halfshaft
adaptors are availible , so Im sure I can sort something out for the sierra ones or do some mating at the hub end. Imagine a jag irs but with the
transaxle where the diff is, and a double wishbone layout and you have where Im heading out back...

price
Rang westfield's today, and apparently the ones I want are from a SXi, 160 quid(ish) +vat and postage per side, which probally makes them nearer
400 than 300 a pair. Oh well, near enough to 300 for me.... Fingers crossed the missus doesnt start totaling what everythings cost before payday

I think id be worried about the exact grade of alloy, the heat treatment it'd have to have after casting, worry over voids in the casting, wall
thickness and strength, finding a competent casting shop, making a design then a casting former for them, and I have to draw the line somewhere at how
much of it Ill make myself, otherwise you could take it to extremes and make your own engine from scratch. And then I truly would never finish...
Its one of them times, where its probally better for me to do a couple of days overtime to pay for bought in ones, rather than spend months on just
one component.
Nice ethos though, just Im concious of time availible as we've just had a baby arrive and Id like to get done before he nicks all my tools for
his pushbike

We were thinking of getting some of their uprights, but cost exceeded need so we had Stuart Taylor ones instead. Steal with sierra hub carriers bolted
to them.

Saab 900 -88 has 4*114,3 and 88-93 has 4*108. Could be hard to find fitting wheels for both of these, but you can always redrill.
I am using the uprights from a -86 saab 900 together with a diff from BMW M5 for my seven project. It seem to be perfect for my car.
