According to Import Tuners' blog, this Lexus IS F is being built with full-track-attack duty in mind. From what we can muster from their editors, the car will sport a custom aerodynamic kit specified for track use that should also look pretty mean on the SEMA show floor.
Filling out the wheel wells will be lightweight RE-30 model forged alloys courtesy of famed motorsport company Volk Racing. Upgraded brakes and stickier rubber, as well as a race-ready interior setup are also on the list of IT's/Tein's must-have parts for the special IS F. As for engine enhancements, nothing has been revealed thus far, but we're expecting a power bump from the 416 hp the IS F's 5.0L V-8 puts out in stock trim.
