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.

Unlock real-world comfort and confidence from your lowered BMW F22 2 Series

This Dinan auxiliary comfort and control pack is the must-have companion for Dinan lowering springs on the BMW F22 platform. Featuring tuned progressive-rate jounce bumpers, it preserves valuable suspension stroke on a lowered car, smooths out sharp impacts and prevents the harsh bottoming that can ruin ride quality and upset balance. The result is a compliant, controlled drive with extra mechanical grip and increased cornering confidence.

We run this setup on customer cars and in-house builds. Feedback is consistently the same: smoother over rough roads, no crashing on big compressions, and noticeably more stability when pressing on. If you want OEM-plus refinement with sharper handling, this is the finishing touch your spring upgrade needs.

  • Progressive bump stops engineered to complement Dinan lowering springs
  • Maximises damper travel on lowered suspension for better compliance
  • Prevents hard bottom-out events for a calmer, more composed ride
  • Adds mechanical grip and improves cornering feel on fast road and track
  • Helps protect shocks by managing full compression more effectively
  • Designed for a balanced, OEM-like ride with enhanced control

Important install note
To achieve the intended ride height, comfort and handling balance, pair these progressive bump stops with the matching Dinan lowering springs. Skipping the companion kit can lead to poor ride and undesirable handling traits. Product defect warranty is maintained, but complaints about ride or handling when the matching components are not installed will not be covered.

Vehicle compatibility
