What is caster and how does increasing it help?

Caster is an alignment angle that affects steering stability and turn-in. Increasing static caster, as these arms do, helps the wheels return to center more readily and can improve the car's desire to go straight on the highway while also making initial steering input feel more responsive.

What is caster wind-back?

Caster wind-back refers to the change in caster angle that occurs when the suspension compresses during cornering. The firmer bushings in these control arms help minimize this change, leading to more consistent alignment angles and predictable handling.

Do these control arms come with all the necessary hardware for installation?

This kit contains two control arms. Refer to the manufacturer's installation instructions for a complete list of required hardware and any additional components needed for proper installation.

Product Details

Whiteline is known for making well-built suspension components that help drivers get more out of their cars. For your 2009-2013 Subaru Forester, these lower front control arms are a solid option if you're looking to improve how the car handles, especially when you're accelerating out of a corner. They come with Whiteline's Anti-Lift Kit built right in, which is designed to give you better traction and grip when you're powering through turns.

What these arms do is increase the static caster on both front wheels. This means the suspension geometry is set up to help the tires stay pointed where you want them under load. The bushings used here are firmer than stock, which helps prevent something called 'caster wind-back' – that's when the alignment angles change too much during hard cornering. By keeping those angles more consistent, you'll notice a sharper, more immediate turn-in response. Plus, the internal grease reservoirs in the bushings mean they stay lubricated for a long time, helping manage friction effectively.

This kit includes two control arms, one for each side of the front suspension. They are a direct replacement for your factory arms, making installation straightforward.
