To counter it, we did not want to greatly increase our spring rate. We felt that the GT-R is a very rough riding car from the factory, and more stiffness in the coilovers would just make things worse.
Instead, we opted to use Forged Performance sway bars. From our research, Forged Performance bars are the stiffest off-the-shelf bars made for the GT-R. We, in particular, wanted a proportionally stiffer rear bar, as the stock rear bar is ridiculously small. It’s so small that we feel that it hardly does anything. The fact that GT-R’s tend to understeer heavily, especially when their tires get hot, also supports this theory.
They use stout construction and Teflon lined spherical bearings which couple the bar very directly.
The sway bar is hollow in order to remain light weight and is constructed of 1096 spring steel for a long service life. It is powdercoated, and all of the included hardware is stainless steel for superior durability as well.
This equates to an over 800% increase in stiffness over stock. You could actually easily bend the stock bar in the car by hand. Like the front bar, the rear bar is constructed of tubular 1096 spring steel, which helps greatly keep the weight down.
