At Cooksport we offer a full race car preparation service and trackside support service. Car Geometry (Race/Track) / Race Car Setup We offer specialised geometry set up services for any car. This is for both road and track and can be carried out in alignment with specific driver goals. This can be condition or track specific or for road cars needing balanced set up for maximum performance. When you have your car geometry set up it involves adjusting the steering and suspension of the car to change the orientation of the wheels in relation to the chassis position. The position of the wheels in relation to the chassis can provide differences in traction, acceleration, tyre temperature but also longevity of tyres amongst other things. The geometry set up a car will often vary based on the driver, the type of location that it is being used within and in what condition. Whether the vehicle is rear wheel drive, front wheel drive, or four wheel drive will affect the chosen geometry set up. Car Toe Adjustment Front Wheel Drive Vehicles Front wheels Toe in · Increase grip · Increase acceleration · Tyres heat up faster leading to reaching point of most grip faster · Increased stress on tyre will decrease the life of the tyre · Reduces responsiveness of steering better for longer faster corners and more stability at high speeds · Can be better for beginners or drivers who don’t react quite as fast Front wheels Toe out · Increase in grip · Increase Acceleration · Tyres heat up faster leading to reaching point of most grip faster · Increased stress on tyre will decrease the life of the tyre · Faster steering better for short winding turns but can lead to instability at high speed and twitchiness on longer corners Front Wheels Zero Toe · Increased life of tyre, usually on road cars for this reason · Often used on endurance races · Top speed of car is increased as less drag · Contributes to equally balanced response on corners leaving other elements of set up to affect car behaviours Rear wheels Toe in · Reduced acceleration and top speed of car · Lengthens effective wheelbase of the car making car more stable through higher speed and longer corners, particularly beneficial on naturally shorted wheelbase vehicles Rear wheels Toe out · Reduces acceleration and the top speed of the car · Slip angle generates heat within tyre faster leading to more grip sooner · Suitable for races with lots of turns in differing directions · Can be more unstable at higher speeds through corners Rear Wheels Zero Toe · Increase acceleration and top speed of the car due to minimum drag · Increased lifespan of tyres · Neutral levels of control through all types of corners · Takes longer for tyres to heat up so grip will come later in the race Rear Wheel Drive Vehicles Front wheels Toe in · Decreased acceleration · Decreased top speed of car when driving in straight line · Lifespan of tyre reduced · Tyre heat will rise quicker leading to more grip earlier on · More stability on high speed corners · Reduced agility in shorter, tighter corners Front wheels Toe out · Increase in grip · Increase Acceleration · Tyres heat up faster leading to reaching point of most grip faster · Increased stress on tyre will decrease the life of the tyre · Faster steering better for short winding turns but can lead to instability at high speed and twitchiness on longer corners Rear wheels Toe in · Improves acceleration of the car due to increased grip reducing wheel spin · Top speed of car reduced · Heat increases in the tyre are earlier in the race leading to increased grip earlier on in race · Life of tyre reduced · Increase tendency to understeer · Increased high speed stability Rear wheels Toe out · Increased acceleration but decreased top speed · Tyre lifespan reduced · Faster tyre temperature increase leading to grip earlier on in race · Higher tendency to oversteer · Less stable through high-speed corners Zero Toe · Reduce acceleration but increase top speed of car as tyre rolling in the direction for highest efficiency · More stable at straight in straight line at high speeds · Lifespan of tyre is increased as takes longer for tyre temperature to increase · Neutral feeling through all speeds of corner Four-wheel drive (4WD) Drive Vehicles Front wheels Toe in · Top speed of car reduced · Tyres will get up to temperature sooner, but lifespan of tyre will be reduced · More stability at high speeds and through high-speed corners · Less agile through corners at low speeds · Front wheels Toe out · Increase Grip and acceleration · Reduce Top speed · Faster tyre temperature increase meaning grip increase earlier in race · More unstable at higher speeds · More agility in car, tight corners navigated easier Rear wheels Toe in · Increase acceleration and reduce top speed · Lifespan of tyre reduced · Reaches operating temperature and optimum grip sooner · Stability at high speeds improved · Less agile in shorter corners · Can feel less responsive Rear wheels Toe out · Increase in tyre temperature earlier leading to increase grip earlier (beneficial for short races) · Lifespan on tyre reduced · Oversteer tendency · More unstable at high speeds Zero Toe · Can lower acceleration · Can increase top speed · Increased lifespan of tyre · Tyres take longer to heat up · Neutral stability through all types of corners Using each of these factors a team or driver will set up the car’s toe in line with the vehicle, the conditions it is being used in, its application, the track, and driver preference amongst other things and the combinations of toe on each wheel will be changed between each race. Road cars will often be set up with zero toe to maximise tyre lifespan and to provide neutrality of response. This is due to the fact that roads will vary dramatically. What is Race set up? What is geometry set up on a car? Race set up or Geometry set up are the same thing. It refers to setting up the car’s toe settings on each wheel alongside the rest of the vehicle to enable the driver to perform in the best way for a specific event. The exception to this is having a performance road car or road car set up to handle a wide range of conditions. The driver and team will decide on each setting based on driver preference, driving conditions and track to optimise performance of the car when being driven. At Cooksport we offer geometry/race car set up for road and track cars. Feel free to reach out to us if you wish to use our services. Contact us for more information. Race Car Preparation Our engineers will analyse and prepare race cars to required championship regulations. If customers choose, can often continue to provide ongoing care of the vehicle throughout a season. We organise post event set down and flow into preparation for next races adjusting accordingly for chosen track/expected conditions. Trackside Support Service Alongside Race Preparation we also offer trackside support service. Our specialist motorsport engineers will be trackside supporting drivers and their vehicles throughout the race event. They will take responsibility for the car allowing the driver to focus on the main job at hand, the racing. They will perform all required checks and maintenance throughout the event and can work with the driver to make any required set up adjustments based on driver feedback between sessions. Depending on series or championship they cover any pitstop or repairs required creating a smooth, fully supported, racing experience. Our team is highly experienced and have provided these services across all areas of motorsport from club racing, British Touring Car, Formula 1 and everything in between.
