b'TECH TIP PAGETech Tip 21: If you draw a line through your upper & lower ball joints,to the ground, that is your cars steering axis. Your cars scrub radiusis the distance from the steering axis to tread centerline at ground level.If the steering axis intersects the center of your tread, that would be Zero Scrub Radius. The tire would literally PIVOT in the center of the tread as the car is steered, providing more grip when turning.Most production cars have 3-6 scrub radius & this causes the tirecontact patch to scrub as the car is steered. This is literally rippingthe tread around the steering axis further inboard, versus simplypivoting at the center of the tread. This dramatically reduces the tires grip on tight corners. All RSRT front suspensions are low, or zero, scrub radiusfor more grip on tight corners!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.Tech Tip 40: Rookie racers believe (or have been told) to set your crossweight at 50/50 when you scale your race car. This is only accurate, if your car has the same left & right side weights, with driver. We achieve this 50/50 L/R in Track-Warriors with optimum placement of the battery, oil dump tank, fire system & other accessory style weight.Production based race cars are left side heavy. 51/49 to 52/48 is common. These cars need the crossweight (LR & RF scales) to match the right side weight for equal left & right handling. If you set left heavy cars at 50/50, they have more grip on left hand corners & less on rights.If you want the car to have equal grip & handling on left & right hand cornersadjust your corner weights on the scales so the crossweight % (LR & RF) match the right side percentage. 835'
