From The Driver SeatMaking major appearance, engine, suspension, and wheel/tire changes to your high-mileage truck or SUV will instantly improve your overall driving experience. The CGS intake and exhaust install improved the engine's throttle response and power. The CGS tuned exhaust decreased back pressure and created a deeper-sounding rumble. Lowering the Tahoe with a DJM Suspension 4/4 drop improved its cornering and braking due to a lower center of gravity and the tighter suspension helped eliminate body roll and less nose diving during braking. Larger 20x81/2-inch Intro custom Sport 5 wheels wrapped in Goodyear Fortera 275/45R20 rubber not only improve the looks, but also contributed to better cornering and braking due to a larger tire tread contact patch with the road surface.
