Maximum Motorsports Road & Track Box for 2011-2014 Mustangs greatly improves handling, pushing cornering power above the 1.2g level, while retaining ride quality suitable for a daily-driven Mustang. For 2005-2010 Mustangs, see the RTB-50 package.

This package is for the driving enthusiast who demands:

• Superior handling for their street-driven Mustang.
• Ride comfort suitable for daily commuting and long trips.
• The ability to enjoy open-tracking or autocrossing with only a minor compromise in performance compared to a Mustang purpose-built for track use.

The Maximum Motorsports Engineering Team fine-tuned this Grip Box through extensive testing. We used a Motec data acquisition system to log-test both street and track sessions. This gave us the precise information we needed to choose swaybar and spring rates for the best combination of ride quality and track performance.
