All wheels use ventilated disc brakes with four-channel anti-lock The NSX's traction-control system regulates power to the rear wheels depending on available traction. It now operates on deceleration as well as acceleration to assist stability NSX boot is located behind the engine and provides 143 litres of space The NSX-T's removable aluminium roof panel weighs 8.8kg Roof panel stores underneath the engine hatch and does not interfere with luggage space Splash guard has been redesigned to provide better cooling for the front brakes To retain the NSX-T's structural strength, Honda has added reinforcement to 50 areas. These include crossmembers, roof rails, pillars and bulkheads "Drive by Wire" system connects accelerator pedal electronically to an electrically driven throttle body Heat-absorbing green glass reduces cabin greenhouse effect Power steering gains torque-sensitive assistance in place of engine-speed controlled assistance Exhaust manifold is made from free-flowing stainless steel, in place of cast ironThe V6 engine has a variable-length intake manifold system to help efficiency at high and low speeds Sparking efficiency is assisted by the use of separate ignition coils for each of the six cylinders Front and rear suspension systems are mounted on cast alloy subframesNSX-T weighs only 45kg more than the coupe version The alloy engine is mounted transversely, ahead of the rear wheels to give the best possible weight distributionHonda says the aluminium NSX-T is about 40 per cent lighter than if it were a steel-bodied, equivalent strength version Double-wishbone design is used on both front and rear suspension
