Give Your S2000 Rear End the Grip It Deserves
The factory rubber bushings in the S2000 rear lower control arm break down quickly under hard cornering and track use, letting the rear axle shift under load and costing you predictable handling. The Whiteline W63442 rear control arm lower inner rear bushing kit swaps in a high density polyurethane formulation that holds its shape far longer than rubber, keeping the rear suspension geometry locked in through every corner.
Key Features
- High density polyurethane resists compression set and deflection found in factory rubber bushings
- Improves rear suspension precision under hard cornering, braking, and track driving
- Reduces unwanted rear axle movement for more consistent, predictable handling
- Direct replacement for the factory lower control arm inner rear bushing position
- Backed by Whiteline’s limited lifetime warranty against defects
- Whiteline part number W63442 for simple reordering and warranty tracking
The W63442 kit is engineered specifically for the S2000 rear suspension layout, so fitment and load ratings match the factory geometry exactly.

FAQ
What is the W63442?
The Whiteline W63442 is a polyurethane rear control arm lower inner rear bushing kit for the Honda S2000 that replaces the factory rubber bushings for tighter, more consistent rear suspension geometry.
Which years of the S2000 does this kit fit?
This kit fits the 2000 through 2009 Honda S2000, covering the full production run of the AP1 and AP2 chassis.
What comes in the kit?
The kit includes 4 polyurethane bushings and 2 steel tubes sized for the rear lower control arm inner rear mounting position.
Does this kit replace the entire control arm?
No, this kit replaces only the bushings and tubes inside the factory lower control arm, so the factory arm is reused.
Will this help with tire wear on my S2000?
Yes, worn rubber bushings allow the rear suspension to shift under load, and replacing them with polyurethane restores proper geometry that helps even out tire wear.
Do I need any special tools to install this kit?
A press or a combination of sockets and a vise is typically needed to remove the old bushings and install the new polyurethane bushings and tubes.
Will I need an alignment after installing this kit?
Yes, a wheel alignment is recommended after installation to confirm the rear suspension geometry is set correctly.
Is this kit suitable for daily driving or only track use?
This kit works well for both daily driven and track focused S2000s since the polyurethane bushings improve durability and handling feedback without compromising ride comfort significantly.
