About This Build
The GT4 RS flat-six screaming to 9000rpm is automotive perfection. This build focuses on track readiness rather than huge power gains. Soul Performance exhaust removes the GPF and adds an intoxicating soundtrack. Dundon headers help the 4.0 breathe freely. KW Clubsport coilovers give adjustability for different tracks. Pagid RSC1 pads handle repeated heavy braking. Softronic tune optimizes fueling with the exhaust mods for a clean 520whp. Every second on track is pure bliss.
