Why Settle for Less?Tech Tip 25: The goal of dialing in your camber, caster & toe is to achieve the largest tire contact patch possible dynamically, when the car is in pitch & roll, under hard braking & turning in the corner. Forget static settings. Dynamic tire contact patch is our focus. Use tire temps across the tire to guide you on how well you are utilizing the entire contact patch. Plus, when the car is in dive, your front CG is lower AND more air flow is going over the car, instead of under it. Both of these benefits add front grip. Of course, the lower the car in dive, the lower the CG & the lower volume of airflow getting under the carthe larger the gain. But when the driver steps off the brakes, deep into the corner, the stored energy from the compressed front springs pushes the front end up in milliseconds. You instantly have less contact patch & a higher CG. In less than a second, youll also have more airflow under the front end. All bad. This is why most cars go into a push condition, upon brake release.Winning Racers learned they could modify the shock bleed circuit to keep the front end tied down for a short, controlled time. This allows the driver to get off the brakes earlier & carry much greater mid-corner speed. This time off the brakes & before throttle is called the roll thru zone. The rest of the time, the shocks work normal. We utilize tie down in all of our Secret Sauce shocks for Autocross, Track & Road Racing.581'
