Product Description

The Whiteline KSB599 adjustable front strut tower brace is developed for early-2000s Subaru performance platforms including the 2002-2007 WRX, 2004-2007 WRX STI and 2004-2008 Forester XT. By linking the front strut towers with a stiff alloy brace and adjustable end-plates, this kit significantly reduces chassis flex, enhances turn-in sharpness and improves steering feedback -- especially during spirited driving or light track use.

Installation is straightforward using the factory strut top-mount bolts, and the adjustable design allows the KSB599 bar to fit varying engine-bay layouts (including larger intercoolers). Its polished alloy finish not only adds visual appeal but also resists corrosion, making it a long-term performance upgrade. Backed by a 3-year/60,000 mile warranty, the KSB599 is an ideal upgrade for Subaru enthusiasts seeking improved handling confidence and chassis responsiveness.
