Ford finally is offering a TrackPack, which includes 255/40ZR-19 P Zero summer tires, stiffer shocks, higher-performance brake pads, a 3.73 axle ratio instead of a 3.31, rear trailing links with stiffer bushings, a strut tower brace, and larger anti-roll bars (the tubular 34mm front bar goes from 5.1 to 5.8 mm wall thickness and the solid rear bar increases from 20 to 24mm). With all of these changes, Ford says maximum grip increases to 0.93 g, while body is reduced a further ten percent.
