Product Description

The Whiteline KTA137 is a pair of adjustable rear toe arms for the 2008-2018 Ford Focus, 2004-2013 Mazda 3, 2008-2013 Volvo C30, and 2004-2012 Volvo S40 -- all sharing the Ford C1/P1 platform architecture. The primary application is correcting rear toe alignment on lowered vehicles, where the factory control arm geometry shifts the rear wheels out of their designed toe range. Running out-of-spec toe causes accelerated and uneven tyre wear, reduces straight-line stability, and blunts cornering grip. The KTA137 extends the available toe adjustment range beyond factory limits and enables precise dialing of rear toe for the driver's specific setup and tyre wear goals.

Each arm uses Whiteline's turnbuckle adjustment design, which allows toe to be set or updated on-car without removing the arm from the vehicle -- a significant convenience during corner weighting or tyre wear checks. Low compliance synthetic elastomer bushings are used throughout to minimize NVH while maximizing durability and alignment stability under load. The alloy arms are anodized for long-term corrosion resistance. Sold as a pair covering both sides. Rear wheel alignment is required after installation. Suspension specialist installation is recommended. Backed by Whiteline's 3-year warranty.
