Cobb's springs lower the STI by 2.2cm on each corner and also feature a 10 per cent increase in springrate on the front and a 20 per cent increase on the rear, which should make for a significant upgrade in handling.
According to a recent test conducted by Motor Trend, Cobb's development mule was also able to turn in a maximum cornering G figure of 1.02g when fitted with the springs - a great improvement over the stock 0.94g, but it must also be noted that Cobb's thicker front and rear anti-roll bars were also fitted during the test. Still, at just $250 USD for a set, they're quite the bargain.
