The controversial FTT device is similar to Benetton's in 1999. Torque shafts transfer the torque from a faster wheel to a slower one to even out the braking distribution, theoretically allowing the drive to brake deeper into the turn and unlock more of the car's front-end grip. There is a software-controlled MOOG electro-hydraulic control valve (1) and a clutch (2).

As part of the TF104B update, the front wing pillars are no longer straight but arched (1). The main profile is higher from the ground (2) making the supports shorter. A new fin on the outside of the endplate (3) is more complex in shape.

The back-end appears very Renault-influenced. The exit chimneys (1) are much longer and there is a new twisted section winglet (2). The fin in front of the rear tyre (3) is longer and more scalloped and the inwards 'Coke bottle' sweep of the monocoque (4) is deeper. The exhaust chimney (5) is not as tall and is more towards the centre of the car.

Jordan invented a new position for its winglet, at the top of the sidepods. It is similar to those seen on the lower bodywork of the cars running guide vanes.
