“This gave Lawrence some food for thought and, looking at the Beetle front suspension, he adapted the principle to give him what he needed.

Duncan Rabagliati’s restored Deep Sanderson Formula
Junior. In its day this car challenged and beat Lotus 18s in the wet
“Instead of having the two trailing-arm pivot axis parallel across the car he angled them down towards the centre, the uppers more than the lower. This gave him the camber recovery he was after with the added benefit of a low roll centre that was completely fixed and would not migrate, no matter what the suspension did.
For his next attempt at a Formula Junior he incorporated this system on both ends of what he was now calling a Deep Sanderson. The name was inspired by a popular jazz tune of the day, Heep Sanderson, with his mother's maiden name substituted for originality. The car rolled out before the end of the 1960 season and Lawrence remembers of the suspension, “I was immediately aware of what it did from the way it performed, particularly compared to the Lotus 18 which was carrying all before it by then.” On its third race it took its first win at a wet Oulton Park meeting in 1960 ahead of one of the all-conquering Lotuses.

Lawrence freely admits that at this stage he was stumbling on something as much by accident as design but he had very clear ideas of what he wanted to achieve. “I was coming at it without any real knowledge of suspension design from a fundamental point of view. But it did exactly what Keith said it should do in spades - total camber recovery. I had it on all four wheels.”
With the suspension, he was also exploring other ideas he had been developing. “I’ve never liked this business of anti-roll bars lifting the inside wheel to make the outside wheels work properly. I call that building a four wheel motorbike. As you can get it into a corner you are only running on two wheels. I adhered to that throughout my career and all my cars have been stunning in the wet. That’s why, because I leave the inside wheel doing something. The car itself is going to transfer weight but I’m not adding to it. Somebody once said, “An anti-roll bar is a quick way to prop up an otherwise inadequate suspension,” and I think that’s right.”

“A low roll centre that was completely fixed and would not migrate no matter what the suspension did”

His partners in the new business were also impressed and one of them, Len Bridge, suggested that, as he obviously had something, why not design it into a road car people would want to buy. So they set about building an open, two-seater prototype powered by a Mini engine behind the seats. It incorporated Lawrence Link suspension on the front but the transverse engine prevented the same system being utilised on the rear.

“We took it to the Nurburgring and Len put it in the top of a tree after the Flugplatz. It wasn’t badly dmaged but it was hideous.” Happy that the chassis worked they decided to make the styling more marketable. “In the winter of 1961 we made the “eggbox” [body buck] for Williams and Pritchard. ” The finished car, designated the Deep Sanderson 301, was shown at the 1963 Racing Car Show.

Like the front, the rear suspension also uses two transverse tubes for the pivots and steeply angled asymetric wishbones. The result in cornering is a wheel pair that moves up and down in an arc and produces full camber recovery in roll
