The most visible of these changes being the relocation of the horizontal fence directly ahead of the winglet, which is mounted lower for '97.   Above right: the same winglet assembly viewed from the side. Though shudder panels may be fitted to the radiator outlet area to improve aerodynamic efficiency at certain circuits, this particular car is devoid of any of these, though the fixture-points are still visible along the ducting.                    Above: rear wing assembly in standard configuration used in 1997. Though this particular setup is still viable for '98 cars, the majority of Reynard-shod teams have opted to use the "wing-foreward" option, which re-locates the aerofoils foreward while the end-plates remain in the same location; thus preserving the longitudinal dimensions of the car.                   Above: rear-wing mounting posts attach to the differential cover via four hexagonal bolts. Additional re-enforcements in the form of horizontal cross-beams help to strengthen the wing assembly, as well as serve as hard-points to jack-up the car in the event of a pneumatic jack failure. The under-wing diffuser is of identical height and width on the '97 and '98 cars, though the centerline housing for the starter-assembly/oil sump is slightly more bulbous on the 97I.
