Does the front suspension look right?

Not mine, but I noticed http://cgi.ebay.co.uk/tts-tuned-stuart-taylor-locoblade_W0QQitemZ150227960058QQihZ005QQcategoryZ29750QQssPageNameZWDVWQQrdZ1QQcmdZViewItem on ebay. IS it me or do the wishbones look to be at odd angles?

Its not you but they are at an angle, just not sure whether its odd or even.

I agree, the top wishbone does look to be
at a steeper angle than normal.
Is the bracket for the top mudguard bracket, attached to the mushroom insert,
lifting the position of the top ball joint?

Yep looks wrong to me..
Have you got Cortina wishbone geometry and Sierra uprights?

Bottom ball joint looks high as well, canted over quite a lot for a car with static loading, so get the bottom wishbone level then look at top

Its not mine! It is on ebay. I was looking as I am building a ST. I was curious as that is not what my setup looks like!

Anyone recognise the car?

Hi it is just set at too low a ride height. All would be correct if chassis was moved up an inch or so.

Dont know anything about the stuart taylor, but I run a magenta lsr which has the same type of suspension set up. It has been explained to me that the reason the top wishbone is at that angle is to try to keep the wheel upright when cornering. As the car rolls the efective length of the wishbone (rotating about its pivot) reduces, moving the top of the wheel closer to the chassis in doing so it keeps a wider contact patch of the tyre in contact with the road.
supposed to help when cornering

Photo's aren't that brilliant (and I'm looking through a Stella induced haze also), but that doesn't look like a 'tina upright. Photo from head on would suggest that the lower wishbones are pretty level.

Nice quote. In my Asdavod haze its lookes well odd. Botttom looks Ok - top looks steep upower.

At our first attempt on putting tubular wishbones on our Locust I ended up with something close to what is shown by the OP.

I moved the top wishbone mounts up by about 1" and ended up with nice parallel bones, same for the steering rack ends, also parallel.

They aren't supposed to be parallel surely?

Have the upper wishbone at such a extreme angle has two disadvantages (1) The virtual swing axle is very short (2) The front roll centre will be high move about an awful lot in roll and with suspension movement.

Parrallel wishbones give a ground level roll static centre, which may or may not be a good idea -- depends a lot on what rear roll centre height is employed. Yes I know F1 cars do generally have wishbones (close to) parrallel but for aerodynamic down load reasons F1 cars have suspension so stiff they (almost) don't roll at all.
The best solution most Sevenish cars somewhere between the two.

Just saw this on the back of a car transporter heading down the M5 along with a Ford Ka (I think). Anyone on here owing up to buying it? £5k seems a good price too!

Hi forgot about this one. As Richard Quinn
says above. The locoblade's had tina uprights on. This one has a sierra upright. One can only imagine that the bottom arm is as original but the top arm has either been changed or shortened. With the sierra being a taller upright setup this is what has thrown the top arm out by increasing the angle. Due the the chassis brkts being in the original tina jigged position.

Although the angle looks like it could be reduced by using a lower profile mushroom insert and changing the wing stay arrangement.
