Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply. We're upfront about this — please be sure of your purchase before ordering.

Eibach E40-20-031-03-11 Roll Control Set for BMW M2, M3, M4

Unlock razor-sharp chassis response and rock-solid cornering confidence with the Eibach E40-20-031-03-11 front and rear roll control set. Engineered for BMW M2 F87, M3 F80 and M4 F82 F83, this uprated stabiliser package tightens body control, boosts lateral grip and maximises steering precision for fast road and track day use, all while maintaining everyday comfort.

Built from cold-formed steel alloy and finished in a tough red powder coat, Eibach’s bars deliver consistent performance and long-term durability. Expect flatter cornering, cleaner exits and a more neutral balance so you can carry speed with confidence on B-roads and circuits alike.

What you will feel

  • Noticeably reduced body movement for flatter, more composed cornering
  • Quicker turn-in and improved mid-corner stability for higher exit speeds
  • Dialled-in balance to curb understeer or tame oversteer for a more neutral chassis
  • Straight-line ride comfort preserved by retaining OE spring behaviour
  • Precision manufacturing from cold-formed steel alloy for repeatable performance
  • Durable red powder coat for corrosion resistance and a quality finish
  • Complete front and rear package with mounting hardware for a clean installation

We run this setup on our own builds and on many customer cars. Feedback is consistently positive: flatter cornering, more mechanical grip and a planted, on-rails feel that inspires confidence on fast road and track sessions.
