The stock Lexus IS 350 delivers impressive performance, its 3.5-liter V-6 getting it from 0 to 60 mph in 5.6 seconds, while still embodying Lexus luxury. Now you can tune up the handling substantially with Lexus' F Sport accessories from the dealer. A tuned-up luxury car may be a strange idea, but it works for the Mercedes-Benz AMG division. We looked at a 2009 IS 350 loaded with F Sport brakes, suspension components, and exhaust. These components make it a car you can take out to track days, although the harsher ride will take some of the luxury out of your commute.
