A high-performance GS F-Sport model will also be available using the same 3.5-liter V6 and will feature high spring rates, a thicker anti-roll bar, firmer adaptive shocks, larger two-piece front brake rotos, four-wheel steering, a variable-ratio rack and 19-inch wheels. The GS will debut on August 18 2011 but Lexus wouldn’t reveal the exact on-sale date. We expect it to be in showrooms sometime in early 2012. The F-Sport model will also go on sale in early 2012 and, an all-wheel drive version of the GS350 will be available sometime around the middle of next year.
