2007 Ford Mustang Shelby GT is one of only 3,385 built, making it a true collectors car. With its powerful 4.6L V8 engine and 5-speed transmission, this Mustang is the one to own. Tons of extras valued at thousands plus includes all OEM stock parts! Kooks long tube headers with highflow cats for a big improvement in exhaust flow, sound, and mid to top end power, especially paired with the tune for 93 octane. JLT cold air intake that increases airflow and induction sound, working hand in hand with the long tubes and tune. Custom tune for 93 octane that takes full advantage of the intake and headers, adding timing, sharpening throttle response, and cleaning up the air/fuel for both power and drivability. Chassis and driving feel: Koni STR struts and shocks that control body motion far better than stock, especially with the Shelby GTs lowered springs, giving you flatter cornering and a more composed ride. Barton short throw shifter delivering shorter, more precise shifts and a confident 23 shift under power. MRT tilting headrest improving comfort and ergonomics, making long drives surprisingly easy in a performancefocused car. Enkei TS5 18x9.5 wheels wrapped in Goodyear Eagle F1 SuperCar 3 275/4018 tires a wider, lighter package on a sticky 200ish treadwear tire thats a huge step up in grip and steering feel versus the original 18s and older allseason rubber. What it feels like on the road: Put together, this combo adds noticeable power over the stock 319 hp Shelby GT, especially above 3,500 rpm. The car turns in sharper, puts power down harder out of corners, and has a stronger, crisper pull all the way to redline. Expect: Roughly an extra 25-35 rwhp over a basic intake/tune car from the long tubes and highflow cats, landing in the neighborhood of about 310-320 rwhp on a typical dynojet (depending on tune and dyno). Noticeably stronger 40-100 mph acceleration and a louder, cleaner exhaust note that sounds aggressive when you ask for it but behaves at cruise. With the Koni STRs, Shelby springs, and the 275wide SuperCar 3s, you get: Flatter cornering and better bump control than the original dampers. A big jump in frontend and midcorner grip with more stable braking and better steering feedback. A slightly firmer but still very streetable ride that makes the car feel buttoned down instead of harsh. Factory components retained and available to go with the car. If you've been hunting for a Shelby GT thats already set up with quality parts, pulls harder than stock, and feels tight and composed
