Bodywork & Aerodynamics

My S1 Exige uses mainly standard but modified bodywork with the addition of several aero devices.


The front clam has had wheel arch louvres cut in to reduce high pressure build up from within the wheel arches. Apart from some vent covers to improve airflow at the front, this clam is standard.


We will now run a updated ally front splitter instead of the old plywood version which runs under the front of the car, joining up with the flat floor and which is fixed directly to the front crash structure. The reduction in the splitter material thickness will also give me more front clearance and allow me to run lower. Dive planes will be incorprated into the vertical endplates for additional downforce.


The rear of the car maintains a standard clam, modified simply to accomodate the wider than standard rear wheels and tyres. It has also been modified at the very back with venting to draw out engine heat.


We have changed the engine cover for a smooth, non-vented example to improve airflow over the back of the car onto the rear wing. The roof is again standard, however with the scoop enlarged to feed the airbox in the engine bay.


The DJ Engineering pre preg carbon, twin element rear wing was designed by renowned aerodynamicist Simon McBeath and is wind tunnel tested. It replaces my older, narrower wing and uses a high efficiency, low drag profile, but is still capable of producing high levels of downforce at high angles of attack. This will be mounted further backwards than my old wing to get the cleanest air, using custom made, adjustable knife-edged struts which are then bolted directly to the rear chassis members. Again, using custom made, high load items.


Also at the back we will be using a new ally diffuser, much wider than the old, standard item and also deeper, but with the same ramp angle. This will join onto a new floor panel which eliminates some of the large wheel area cut-outs on the standard part, allowing the diffuser to drive the rest of the flat floor as efficiently as possible and to interact with the rear wing.


For the sides of the car, between the front and rear wheels we will produce and mount some wide running boards, in order to help with the airflow under the car, again maximising what's available to us.
