Project IS F by Five Axis

Lexus Description: Following its stunning debut in 2007, the Five Axis Project IS F went back to the shop for another makeover, this time in the engine compartment. With 416 hp on tap right out of the box, the standard IS F is no slouch. But the Project IS F concept brief included exploring the performance potential of its direct-injected 5.0-liter V8, so it now sports 5.8 liters while receiving ported and flowed cylinder heads, a new exhaust system and changes to the electronic controls. The upshot is enough power and torque to put an evil grin on even the most jaded enthusiast's face.

IS 350 with F-Sport Accessories

Lexus Description: The IS 250/350 is Lexus' entry point into the luxury sport sedan arena. It's a tuner-friendly and robust platform that responds extremely well to performance upgrades. This car is fully loaded with all the offerings from the F-Sport performance accessory catalog. It also sports a new concept ground-effects body kit designed to complement the increased performance and aggressive stance provided by the F-Sport components

IS F by Fox Marketing/Artisan Performance

Lexus Description:Fox Marketing and Artisan Performance teamed to create this subtle yet aggressive makeover of the already aggressive IS F. The subtle part involves the numerous bodywork changes, which enhance rather than rethink the lines of the IS F, making it look even more muscular in the process. 'Aggressive' can be applied to the engine which gets the full twin-turbo treatment. Fox expects the changes will yield something north of 600 horsepower.

IS F by Import Tuner Magazine/TEIN

Lexus Description: Import Tuner Magazine and TEIN suspension company put their collective heads and expertise together to create an IS F that's focused on track performance, while still remaining practical for the street. Weight reduction, added chassis stiffness, special suspension and big sticky tires take care of the corners, while a comprehensive nitrous system boosts the engine for bursts of overtaking power. Coming soon to a track near you.

IS F by 0-60 Magazine

Lexus Description: With track performance a common theme among IS F builders, 0-60 Magazine ups the ante on their IS F project with a supercharger to tease out another load of horses from the big V8. Carbon fiber body components reduce weight while lowering the center of gravity and a custom roll cage adds stiffness and protection. A beefy brakeupgrade kit was added to balance the performance equation.

IS F by MotorworldHype.com

Lexus Description: MotorworldHype has taken another path that is a bit less aggressive, yet more easily accessible for the average consumer. Lots of carbon to reduce some unwanted mass and a well-rounded package of suspension, brake, engine and cosmetic changes provide sharper responses in all directions.
