Product Description

The SPL RTA 981 adjustable rear toe arms are designed specifically for the Porsche Boxster and Cayman (981 chassis) from 2013 to 2016. These arms replace the factory rear toe links with precision-machined gun-drilled aluminum links and high-performance rod ends, eliminating the compliance and deflection of stock rubber bushings. The result is sharper rear handling, more predictable behaviour under load, and superior alignment control - especially important for lowered cars, wider tyres, or track usage.

Installation involves removing the OEM rear toe arms, installing the SPL units, setting your desired toe and bump-steer parameters, then locking the settings using the rotating clamp system. A full wheel alignment is strongly recommended afterward. Fitment is confirmed through 2016; model year 2017 or later vehicles requiring different chassis codes or components are **unconfirmed** at time of listing.
