Disclosure ↗

01 / Before price

Four checks before
you choose a seller.

Do not assume G80 rear parts transfer to the G82 coupe; trunk, spoiler and diffuser geometry can differ.

01

Body style

Sedan, coupe and convertible rear geometry must remain separate.

02

Exhaust layout

Tip diameter and aftermarket exhaust position can change diffuser clearance.

03

Sensor clearance

Parking sensors, radar and cameras need explicit compatibility.

04

Bumper removal

Removal raises labor cost and the impact of a failed test fit.
