Dinan Ride Quality & Handling Kit - BMW 340i/440i, 428i/430i/435i (F30/F32/F36)

Lowering springs shorten the distance the suspension can travel before it hits the factory bump stops. On a lowered 340i or 440i that can mean a harsh ride over bumps and less predictable handling. Dinan's kit is the companion piece to its spring set: replacement bump stops tuned for the lower ride height.

What you get

• Progressive-rate bump stops that firm up gradually instead of all at once.
• Tuned for Dinan's springs, so the car keeps more usable suspension travel after the drop.
• Better ride and handling than running the lowering springs on their own, according to Dinan.

Good to know

• This kit is meant to go in alongside Dinan performance springs. It is not a lowering kit by itself.
• Fitting it at the same time as the springs saves doing the strut work twice.
