Going beyond its Foundation counterpart, the Dinan Experience packages address not only the engine but also the chassis for a complete solution in the form of a wholly tuned Dinan vehicle. While adding power modifiers is often the go to path when beginning the modification journey, it does not fully consider what makes the car infinitely more enjoyable in scenarios outside of WOT pulls. With the addition of suspension upgrades integrated alongside the power adders the vehicle is transformed into something more than just the sum of its parts. It's a comprehensive answer to delivering additional technical capabilities in the form of increased engine performance and better handling along with improvements to aesthetics (looks and sound) in a package designed with reliability and safety in mind. This union of power and handling modifications results in a true OEM+ experience - the Dinan Experience.
