Importantly, the heavily criticized rear suspension was decambered, incorporating what Triumph called a "swing spring". One leaf of the suspension "stack" was eliminated and only the bottom leaf was attached rigidly to the differential. The remaining leaves were mounted to pivot freely — eliminating the worst characteristics of the original swing-axle. This was a different approach than that taken with the Triumph GT6 Mk II (GT6+) and Triumph Vitesse Mark 2, both of which received new lower wishbones and Rotoflex half-shaft couplings. The result on all these cars was improved handling.
