Next, we moved to the driveshaft tunnel to install the Granatelli g-load brace and driveshaft loop combo (top, $149). The driveshaft loop is a safety device; a bonus for us, though designed primarily for a higher-horsepower or racing applications. Of all the components we're installing, we're most impressed with this one in terms of quality for price. It looks and feels bulletproof. Made from heavy-gauge steel, it makes the factory brace (bottom) look like corrugated tinfoil and has less than half the thickness of the GMS unit. Installed, the new brace should increase central chassis torsional stiffness, particularly during hard acceleration.
