Rear Suspension

I'm going for semi-triangulated 4-link. It will allow me to re-use the trailing mounts on the chassis, an a-frame wasn't possible due to the mid-mounted engine, I'm hoping to get a balanced suspension - front <-> rear, but because of the limited places I could place the mounts, the geometry isn't as good as the front.

It will be interesting to see how a vehicle with lots of front travel and decent rear travel, compares to our traditional Land Rovers with very limited front travel.

 

First fine yourself some raw materials.

On the left a Land Rover trailing arm.

On the right some 48mm OD seamless tube, with 7mm wall thickness.

Bend up the fat pipe to suit the mounting points, and then use a Land Rover trailing arm and some 5mm plate to reinforce the bend.
Plenty of articulation possible with no springs
Design of the inner links is far from ideal, but with a sump and oil pump and filters in the way - what can you do ?

I suspect retained rear springs will alleviate the need for any retaining straps, the prop angles are a bit easier on the back.
