The Eibach 29mm Front Anti-Roll Kit (E40-82-089-01-10) is a front-only sway bar for the 2020 Toyota GR Supra A90. Eibach manufactures its ANTI-ROLL-KIT from cold-formed steel alloy, finishes it in a long-lasting red powder coat, and includes all mounting hardware. The stated goal is a stiffer bar than stock, which reduces body roll and sharpens front grip in corners. That is the case for paying more than a stock bar costs.
Owners on user forums say the tubular front bar is noticeably lighter than a competing bar while reaching similar or greater stiffness. The manufacturer lists the front bar as tubular and three-way adjustable, which lets you tune front roll stiffness for different surfaces. One owner who used one through track days and autocross events reported the adjustability worked well across conditions. Use it for 2020 GR Supra front sway bar, A90 Supra adjustable anti-roll bar, and 29mm tubular front sway bar searches.
Fitment varies by source, so confirm your model year with the manufacturer before ordering. The manufacturer's front-and-rear kit page covers 2020-2026 Toyota GR Supra 3.0L RWD A90 with automatic transmission, while other listings show narrower year ranges. The bar is designed to complement Eibach's PRO-KIT and SPORTLINE lowering springs. For DIY, owners on user forums describe the install as doable at home with standard hand tools and good instructions.
No. The manufacturer lists a rear-only anti-roll kit separately, and a front-and-rear kit is sold as its own part number. This listing covers the front bar only.
Sources conflict. The manufacturer's front-and-rear kit page lists 2020 through 2026 A90 applications, but some listings show narrower ranges. Confirm your specific year and trim with Eibach before ordering.
Owners on user forums report a successful home installation with standard hand tools and clear instructions. Plan for a lift or jack stands, and do not rely on a jack alone.
Owners on user forums describe this as a manageable weekend job with standard hand tools, provided the car is raised securely on a lift or jack stands. Eibach's anti-roll kit instruction sheets generally advise lubricating the new bushings with the supplied lubricant before fitting them to the bar. Set the end-link position to your intended stiffness before final torquing, because that position controls the bar's effective rate. Torque values for the Supra should come from the manufacturer's install sheet rather than a general guide.
