......On the 22 you have the ability to raise the inner rear hinge pin from LRC to HRC. The total height change is almost 1mm between the two positions. The LRC will allow the car to roll more over the rear end while also inducing more dogbone plunge. The increase in dogbone plunge will increase the bind of the dogbone pin as it moves in and out of the outdrive during compression of the suspension. Ultimately an increase in dogbone plunge creates more forward traction via mechanical bind. Also when you land off jumps on power you will have more bottoming resistance.
HRC will provide less dogbone plunge and a higher pin height. The higher pin height will reduce the rear lateral roll and give more support via suspension. The HRC will provide more offpower steering as it will provide more support over the rear end and making the weight transfer to the front. With higher roll center you will have less dogbone plunge giving you less forward grip and less mechanical support via dogbone and outdrive.
