Tighten Up the FA20: BLOX Racing Front and Rear Sway Bars for 2013+ Scion FRS and Toyota 86
The BLOX BLOBXSS-10110-SET delivers a matched front and rear sway bar upgrade for the 2013-2021 Scion FRS, Toyota 86, and Subaru BRZ, targeting the platform's well-documented tendency to rotate the rear under lift-off and transition conditions.
The front bar measures 21mm and the rear measures 17mm, both manufactured from SAE 9254 spring steel, shot-peened and heat-treated for fatigue resistance. New Teflon-lined bushings replace the OEM rubber for improved responsiveness without the clunk associated with solid poly bushings.
New rubber mounts are included in the BLOBXSS-10110-SET and OEM hardware is reused, making installation straightforward. This set is designed to reduce understeer and sharpen turn-in response on the FA20-powered Scion FRS and Toyota 86 without producing an unpredictable or harsh ride for street or occasional track use.

Frequently Asked Questions
What is the BLOBXSS-10110-SET?
The BLOBXSS-10110-SET is the BLOX Racing matched front and rear sway bar set for the 2013+ Scion FRS, Toyota 86, and Subaru BRZ. It includes a 21mm front sway bar and 17mm rear sway bar made from SAE 9254 spring steel, with Teflon-lined bushings and new rubber mounts, designed to improve handling balance on the FA20-powered platform.
What are the diameters of each bar in the BLOBXSS-10110-SET?
The BLOBXSS-10110-SET includes a 21mm front sway bar and a 17mm rear sway bar. The larger front bar reduces understeer while the rear bar increases rotation tendency for a more neutral handling balance on the FRS and 86.
Does BLOBXSS-10110-SET fit the Subaru BRZ?
Yes. The BLOBXSS-10110-SET is compatible with the 2013-2021 Subaru BRZ in addition to the Scion FRS and Toyota 86 as all three share the same platform and suspension architecture.
Will the BLOBXSS-10110-SET work with coilovers on the FRS or 86?
Yes. The BLOBXSS-10110-SET sway bars replace the OEM units and work with any coilover system that retains the factory sway bar mounting points. No special clearance issues are expected with common FRS and 86 coilover kits.
Do Teflon-lined bushings make noise compared to stock?
Teflon-lined bushings in the BLOBXSS-10110-SET are engineered to provide improved response with minimal noise. Unlike solid polyurethane bushings, Teflon-lined units typically eliminate the squeaking and clunking commonly associated with poly upgrades while still providing better responsiveness than soft OEM rubber.
Is BLOBXSS-10110-SET suitable for track days on the FRS or 86?
Yes. The sway bar sizes in the BLOBXSS-10110-SET are well-suited to street and light track use on the Scion FRS and Toyota 86, providing a noticeable improvement in cornering balance without introducing the abruptness of extreme performance setups. For dedicated time-attack builds, larger adjustable sway bars may offer greater tunability.
Does installation of BLOBXSS-10110-SET require alignment after fitting?
Sway bar replacement typically does not affect alignment settings. However, if the vehicle is lifted or lowered to access the sway bar end links during installation, an alignment check afterward is always a good practice.
Do I need to reuse the OEM sway bar end links with BLOBXSS-10110-SET?
Yes. The BLOBXSS-10110-SET is designed to reuse the factory sway bar end links. Inspect the OEM end links for wear before reinstalling and replace them if there is any play or noise before installing the new bars.
