Frequently Asked Questions
- Does this work without the Rear Diffuser Trim? No. The Extension bolts to the Rear Diffuser Trim. Order both together if you do not already have the Trim installed.
- Why is the variant selection trim-specific? The 2024+ Model 3 Performance, Long Range AWD, and Long Range RWD have different lower bumper geometry. Each fitment variant is shaped specifically to the corresponding trim.
- Will this fit my RWD Standard Range Model 3? The Long Range RWD fitment variant fits the Standard Range RWD too, since both share the same lower bumper. Select Long Range RWD at checkout.
- Does the Extension change the aero behavior of the rear? Yes. Extending the diffuser further below the bumper line improves underbody airflow management at speed.
- What is the typical lead time? 1 to 2 weeks for in-stock fitments; we will confirm at the order stage.
- Can I install this myself? Yes. The Extension bolts to the Diffuser Trim using included hardware. Plan 30 to 45 minutes.
