Review Design front suspension
I have designed (well throw all parts together) and came up with this design.
But Im not sure about the camber change. Looks to me that it is too much when the suspension compress.
The layout:
-Ford Cortina/ Raceleda uprights
-165/65R14 Tyre
-top arm is 210mm long (centre-to-centre)
-bottom arm is 140mm long (centre-to centre)
-Roll centre height is 65mm
What do the experts think?

The arms seem rather short at first glance.

Yes a locost has a lower A-arm of 350mm wide, but I dont have the room for that.
The R1 model sits in the way.

Whats the off set on the wheel?
Could you use a wheel with as much off set as possible might be able to get add a bit to the wishbone lengths then.....

Looking at other BEC installs, could the engine not be moved a bit further back and over towards the centre line of the car?
In your drawing it looks as though you have the engine and gearbox parallel to the centreline and therefore a straight propshaft. Don't most
BEC installations purposely angle the engine/gearbox to allow for an angled prop (wear, balance, vibration etc)?
This would give you the room you need for longer wishbones.

The engine has to stay parallel to the centre line of the car.

The offset is standard Locost/ Ford.
Hmm, is it an option to have the propshaft under a slight angle?(@topview)
Then I could offset the engine a bit.
Currently the oil filter + 50mm wide chassis rails consumes a lot of space.

There is nothing wrong in having the propshaft at an angle.

In fact it is desireable as the UV's will work better.
