Description
Eibach developed this Anti-Roll application for 2020-2026 BMW M3 / M4 & 2023-2026 BMW M2 (G8X) to tighten chassis transitions and reduce excess roll while leaving the primary spring and damper package unchanged.
Because anti-roll bars also influence front-to-rear handling balance, the selected axle or complete-kit configuration matters just as much as the bar diameter itself.
Application focus: This page is tied to chassis G87, G80, G82; engine/application 3.0LTT; drivetrain RWD, AWD; trim/submodel COMPETITION. Those details matter because Eibach may assign different components within the same model generation.
What makes this application specific: Eibach identifies rear specification 25.40mm for this listing. It should not be assumed interchangeable with another year, trim, or chassis that uses the same product family.
Why This Eibach Setup Makes Sense
- Precision-Tuned for Balance and Control:
- Increased Vehicle Stability:
- Compatible with OEM and Performance Setups:
- Engineered and Tested for Each Vehicle Application:
- Made by Eibach in the USA
Choosing the Correct Variant
Choose the front, rear, or complete-kit option according to the handling change you want. Bar diameter is a specification of the selected part rather than a separate customer choice.
