Now that Lexus’ F-Sport accessories are available for the entire IS & GS lineups, the next question is which parts should be bought first. Well, Edmunds’ Inside Line has the scoop on F-Sport, testing the modifications on an IS 250. Some of the results were very surprising:
Powerslides are impossible with the big tires and little engine, but this car scorches our track with handling numbers that exceed the performance of the mighty IS-F. No, we’re not kidding. This IS runs 71 mph through our slalom, circles our skid pad at 0.89g of lateral grip and stops from 60 mph in just 109 feet.
The last IS-F we tested managed 70.2 mph in the slalom, recorded 0.93g on the skid pad and stopped from 60 mph in 112 feet.
We couldn’t believe it either. But the best part is the F Sport’s highway ride. If you bought an IS-F, you’re probably a regular at the chiropractor by now, but this IS actually rides well, and there’s even less impact harshness than in a stock IS 250.
The improved cornering was credited to the Blisten shocks — which should make them a priority for anyone looking to outfit their IS. Also recommended in the article were the anti-roll bars, the upgraded brakes, and the quick throw shifter.
Beyond that, Edmunds suggests that interested parties pass on the engine cover & exhaust system, and instead invest in a nice, sticky pair of tires.
