ISF Performance

At the front of the vehicle, we find a modern variation on the double-wishbone design. The system also uses a coil-over-style shock absorber and spring assembly. Monotube gas-pressure shock absorbers are employed with stiffer springs and a larger stabilizer bar—all optimized to precisely control body, wheel and suspension motion.

The rear suspension is also a contemporary twist on the classic double wishbone, this time in multi-link form. Like the front suspension, it has been extensively modified and tuned for high-performance duty, using higher rate springs and monotube shock absorbers with damping curves tailored to the IS F.

The extensive reworking of the suspension that occurred in 2011 included reduced spring rates, larger anti-roll bars, longer bump stops and more. These modifications have carried over to the 2012 IS F, and they make it more than competitive with other vehicles in its class.
