Auto Guide has put together a review of the F-Sport performance accessories available for the Lexus IS 350, and came away impressed with the results—here are some of their observations:
We did note the sexy new timbre to the motor’s voice [due to the F-Sport intake & exhaust], however. Tipping the throttle produces an aggressive, deep bellow from the V6, as opposed to the sanitary silence of the stocker. Conversations inside the car became slightly more difficult and we wondered how well the voice-activated Bluetooth/Navigation system might react to the additional decibels.
Also, where the 18-inch wheels and “summer” tires which come as a part of the $5100 Navigation/DVD package will generate true speed of only 78 miles per hour when the speedometer needle points to 80, the 19-inch F-Sport wheels and tires register 81 miles per hour due to their greater circumference, as verified with a Garmin Nuvi GPS unit.
Auto Guide does suggest that the stock suspension on the IS is in “Camry” territory, which I had to shake my head at, but for the most part the review gives a very accurate account of what the F-Sport accessories can offer.
