String Theory Garage will be closed to the public from Wednesday, 29th July to Thursday, 6th August for our annual shutdown.
If you need to get in touch, please leave us a voicemail or send an email. Our team will happily get back to you when we return on Friday, 7th August.
Shopping online? Don't worry! Our online store will remain active! We hope to ship orders placed for in-stock items as normal during the shutdown. Anything else will be dealt with upon our return.
Thank you for your understanding, String Theory Garage Team
Eibach Anti-Roll Bar Kit — BMW M2 (F87) / M3 (F80) / M4 (F82, F83)
Springs and dampers control how the car moves up and down — the anti-roll bars control how much it leans. Eibach's Anti-Roll-Kit swaps both the front and rear factory bars for cold-formed, aircraft-grade steel items that are noticeably stiffer, cutting body roll and sharpening turn-in without touching ride height.
Technical specification
Front bar: Ø29mm, tubular, non-adjustable
Rear bar: Ø26mm, tubular, non-adjustable
Finish: Long-life dark red powder coat
Included: Full mounting hardware and fitting instructions
BMW M3 Saloon (F80), M3 Competition, M3 CS — 04.2012 to 10.2018
Also fits M2 (F87) and M4 (F82/F83) — get in touch if you need one of these listed separately
Why add an anti-roll bar kit on top of lowering springs?
A spring or coilover upgrade alone will lower the car and firm up vertical control, but it does very little for outright roll stiffness. Pairing this kit with your Pro-Kit or Sportline PLUS springs is the more complete way to sharpen the car's handling balance — particularly useful if you're finding mid-corner body movement is holding the car back on track.
We can supply and fit this alongside a spring or coilover upgrade in the same session — ask us about combined fitting rates.
