The reasons for the SketchUp plan was the thought that the standard McPherson struts would get in the way too much of the engine/turbos, so I purchased nice and cheaply from Ebay a pair of Triumph Spitfire front suspension units, which are dual-wishbone, and nicely self-contained in a fairly small package.
To mount these, a sort of chassis-extension is required to get them to the correct distance apart, and the correct height – hence the plan.
We constructed this from a bit of 2×4 timber, to see what it would be like once attached to the car.
Once the engine is lowered into place, we can see how it all sits together.
Unfortunately… the positioning required for the steering rack will put it right through the bottom of the block – so this idea is looking unlikely.
