AST Adjustable Lowering Springs + Dinan Supplemental Ride Kit | BMW F97 F98 X3M X4M

Wheel gap is easy to fix. The details are where we earn our keep.

AST Adjustable Lowering Springs give you control over how your X3M or X4M sits. Because “that’s how low the springs go” isn’t much of a strategy when you have a specific fitment in mind.

We’ve paired them with the Dinan Supplemental Ride Quality & Handling Kit because bump stops belong in the suspension conversation—even if they’ll never get their own Instagram post.

Lowering changes the available compression travel. The bump stops influence how the suspension responds as that travel gets used. They deserve more consideration than “just reuse whatever’s in there.”

That’s the ORT approach. We love a properly lowered BMW. We also care what happens after you pull out of the driveway.

Included:

• AST Adjustable Lowering Springs

• Dinan Supplemental Ride Quality & Handling Kit — D193-9701, with four progressive bump stops
