You can see how the Whiteline bushing cants the lower control arm inward, which moves the control arm forward, increasing positive caster. You can also see how the cutouts in the bushing allow for the arm to pivot up and down, but the bushing’s solid center resists side-to-side and fore and aft movement.
This makes the bar about 20% stiffer. The Whiteline bar is adjustable, and if the inner stiff position is used, the stiffness increases about another 20%.
With the Whiteline urethane bushings elimination of squishy rubber, squishy rubber that was worn out and hammered from many street miles, our car feels a lot better. Gone is the vague disconnection that the stock car had. The ride is just a little bit harsher, with harder bushings more road vibration comes through, but the car feels much more precise which makes it all worth it.
The Whiteline front and rear sway bars also helped by reducing body roll. Their adjustability will come in handy later when we dial-in the car at the track. With the rear bar being 5x stiffer than stock, understeer has been significantly reduced.
Now our car has a pretty solid foundation for more suspension mods we have planned. Stay tuned-in for our next installment, we get our car back on the road with some coilovers from Fortune Auto!
