Motor Trend took delivery of a Lexus IS 250 deked out with the entire F-Sport catalog, and was generally impressed with the difference the factory modifications made:
The brakes, for example, are of the same six-piston front, four-piston rear, two-piece ventilated and drilled rotor design found on the IS F — and they’re brilliant, hauling the car down from freeway speeds with tenacity and a firm pedal. The clutch is fantastic too, with wonderfully predictable take-up and a firm, but unobtrusive feel. The suspension, on the other hand seems a bit of a let down on Southern California roads.
Oh, and Lexus has also tested its equipment on the track, unlike so many posers. In fact, at their California testing venue, Lexus claimed the full F-Sport equipped IS 250 ran an average of just over three seconds faster per lap than a stock version. Assuming accurate timing, it’s hard to argue with that.
With all the F-Sport mods applied to a single car, the cost is substantial, jumping from the IS 250’s base price of $31,220 to $45,548. Of course, I don’t imagine that would be a very common occurrence, it’s much more likely to be bought piecemeal based on the driver’s preference.
