FAQ
What is the W83172?The W83172 is a Whiteline front lower inner control arm caster correction bushing made from synthetic elastomer for the Pontiac G8 and GTO. It increases static caster and dynamic negative camber gain for improved cornering grip and stability.
What does increasing caster do for handling?Increased caster improves straight-line stability, steering self-centering, and cornering grip, especially at higher speeds.
Does this bushing improve braking performance?Yes, the firmer synthetic elastomer bushing reduces suspension deflection under braking, which improves overall braking feel and performance.
Is this a direct bolt-in replacement?Yes, it installs at the factory front lower inner control arm bushing location with no cutting or modification required.
Does this fit both the Pontiac G8 and GTO?Yes, this bushing fits the 2008-2009 Pontiac G8 and the 2004-2006 Pontiac GTO.
Is this bushing suitable for daily driving or only track use?The synthetic elastomer compound is designed to perform well in both daily street driving and more demanding track applications.
Does this kit include a warranty?Yes, it is covered by Whiteline's lifetime limited warranty against manufacturing defects.
