Stop Rear Subframe Movement From Robbing Your G8 Of Cornering Confidence
Soft factory rear crossmember bushings allow the rear subframe to shift under load, causing inconsistent handling and vague feedback through corners. The Whiteline W93165 rear crossmember mount bushing kit replaces those factory bushings to dramatically reduce rear crossmember misalignment and movement, giving the rear end a more positive, connected feel during cornering.
Key Features
- Reduces rear crossmember misalignment and movement under load
- Delivers a more positive, connected feel from the rear end while cornering
- Recommended for motorsport and performance driving applications
- Direct replacement for the factory rear subframe mount bushings
- W93165 uses Whiteline's durable synthetic elastomer bushing compound
- Improves consistency of rear suspension geometry lap after lap

FAQ
What is the W93165?The W93165 is a Whiteline rear crossmember mount bushing kit for the Pontiac G8 that reduces rear subframe movement and misalignment for a more connected cornering feel.
Why does rear crossmember movement affect handling?A shifting rear subframe changes suspension geometry unpredictably under load, which makes the rear end feel vague and inconsistent through corners.
Is this kit recommended for track use?Yes, Whiteline recommends this bushing kit for motorsport and performance driving applications where consistent rear geometry matters most.
Does this replace the factory rubber bushings?Yes, it is a direct replacement for the factory rear crossmember mount bushings at the same mounting location.
Which Pontiac G8 model years does this fit?This kit fits the 2008-2009 Pontiac G8, covering the vehicle's full production run.
Will this bushing kit cause extra noise or vibration on the street?The synthetic elastomer compound is firmer than factory rubber but is engineered to balance improved control with acceptable street comfort.
Is a warranty included with this kit?Yes, the W93165 is backed by Whiteline's lifetime limited warranty against manufacturing defects.
Does installation require special tools?Basic hand tools and a jack and stands are typically sufficient, though a shop press may help when removing tight factory bushings.
