Chassis Flex now there is a subject near and dear to my heart.

What chassis flex does is allow you to change the stiffness of a spring that connects the front and rear suspension. The effect being to either soften or stiffen the overall response of the chassis and affect the distribution of the weight transfer between the front and rear. It does absolutely nothing to increase or decrease the total weight transfer from the inside to outside wheels. What it does affect is how that weight transfer is distributed between the front and rear tires. Depending on how you have your front and rear suspension setup that can be a good thing or bad. So stiffer chassis the more connected the front and rear suspension are and the softer the less… Flex also affects the overall response, stiffer the quicker the car responds, softer well you get the idea.

The biggest reason chassis flex is needed is because these cars we race are so complex most racers do not fully understand how to adjust the handling by changing springs, anti-roll bars, caster, camber, camber gain, roll centres…. There are more than enough ways to adjust the handling using what I just mentioned without throwing in another variable. In reality you can get a much better handling car by leaving the flex alone and adjusting the suspension geometry to achieve the desired result. IMHO
