The 488 GTB's transformation into a Spider has involved more work this time around: there's an additional vertical aluminum panel by the front axle, and a horizontal one at the rear of the car. Ferrari is a little cagey on actual figures, but we're told 488 Spider is 20 percent more torsionally rigid than its predecessor. That feels like a big improvement. The Spider smothers bumps like Don Corleone with a pillow and a score to settle. There's no jarring, no shaking, and it's a struggle to differentiate the Spider driving experience from the fixed-roof GTB.
