TFDON

I recent purchased a TF160 which I intend to run in a handicap sprint championship. The handicap algorithm has a component for rear suspension type but I have been struggling to find an adequate description for the TF.
The multi-link rear axle is actually what can be described as a rigid/live axle with the links controlling longitudinal and transverse movement of the rear wheel - I think.
Hence that would put the TF in the category of rigid axle +trailing arms + coil springs.
Is this correct ?
