The GT350R takes road-racing track prowess to the next level over the Shelby GT350 announced last year by ditching anything that wasn't imperative for speed.The track-ready GT350R rides on a specially tuned suspension with magnetically controlled shocks like the standard GT350, though the R gets you unique spring rates and anti-roll bars plus a lower ride height and a track-tuned alignment. Under the hood is more horsepower from the flat-plane crankshaft V-8, now making more than 500 horsepower and giving it the honor as the most powerful naturally aspirated engine Ford has ever produced.
