All Pre and Post-War Atalantas had
independant front and rear suspension, giving unique road-holding.
The key points to note with RGS Atalantas are the types of front and rear suspension components, as in the photo above. These were often mounted on the purchaser's own, or other, chassis.
suspension had two pairs of trailing arms from which the wheel mounts hung.
Initially these trailing arms were fabricated from tubes but later Dick
Shattock had castings made. The centre of the leading plates holding the
trailing arms was attached to a five-leaved torsion bar acting as the “spring”.
Vertical coil springs were used in most pre-war Atalantas and in the first RGS
Atalanta, MMX 343.
The rear suspension consisted of an
alloy suspension arm which actuated a rod down the centre of, and compressing, a large
suspension spring running parallel with the inside of the chassis.
Dick Shattock always claimed that it was
these finely tuned suspension units which gave Atalantas such good road
holding, especially in the wet and especially with the (then) new Michelin
radial ply tyres, enabling him to equal or beat “works” cars in some
events, most notably the "works"Jaguars, "works" Aston Martins and HWMs at the British Empire Trophy Race at Oulton Park on April 2, 1955.
