The BYD Tang DM-i is a premium SUV with a vulnerable habit: its front bumper sits low and proud, and its rear bumper takes every reversing bump and tailgate-loading scuff. Paint repair on a big SUV is never cheap. The Maremlyn Front Lip and Rear Diffuser Kit for BYD Tang DM-i — a two-piece set in automotive-grade ABS — is built to be as much armor as styling. Here's how the front lip and rear diffuser hold up.
Front Lip: First Line of Defence
The front lip follows the Tang DM-i's bumper contour with a 1:1 original-car mold, so it reads as an extended factory line rather than a bolt-on. Its real job is absorption: it sits slightly lower than the bare bumper, becoming the first contact point for curbs, speed bumps and highway stone chips.
- Impact-resistant thick ABS flexes and rebounds on light contact — a scuffed lip is a cheap fix, a scuffed bumper is not.
- UV-stabilized and scratch-resistant, so it holds its color and finish through long outdoor exposure without yellowing.

Aerodynamic sport profile smooths airflow under the fascia and adds a planted, aggressive stance without changing ride height.
Rear Lip (Rear Diffuser): The Silent Protector
The rear is the danger zone owners forget until it's too late. Reversing into low bollards and dragging cargo over the tailgate sill all land on the lower bumper. The Maremlyn rear diffuser covers exactly that vulnerable band — low-speed reversing contact that would have scuffed the paint now lands on the diffuser, whose raised fins also clean up the airflow for a sportier rear finish.
Material, Fitment & Install
The kit is injection-molded from automotive-grade ABS — the same material family as factory bumpers — chosen for impact resistance, UV stability, waterproofing and scratch resistance. Tooling comes from Guangzhou Yangdugang Auto Accessories (four production bases, 300+ design patents), so panel gaps are consistent and corners don't warp.
Install is deliberately de-risked: 1:1 mold means no cutting, trimming or polishing, and the drill-free self-adhesive system with full mounting hardware means no holes in the body, no paint damage and a fully reversible upgrade. A two-person garage job in an afternoon, no body shop visit.
Verdict
Overall: 8.8/10 — Recommended. This is one of the few exterior upgrades that pays for itself in avoided paint repairs. Want to see it on a real car first?
