The Ghibli's boot lid edge is long and gently curved, so it benefits from an extra pair of hands to check alignment before committing. This guide covers the fitting process for our Maserati Ghibli Rear Spoiler, fitting the M157 generation, 2013 onward.
Tools you'll need
- Isopropyl alcohol (IPA) or a dedicated panel prep wipe
- Microfibre cloths (lint free)
- Masking tape and a tape measure
- Automotive grade double sided adhesive tape or panel bonding adhesive (usually supplied with the spoiler)
- A second pair of hands to help hold position while you check alignment
Step 1: Check your fitment
Confirm you have the M157 generation Ghibli, 2013 onward, before ordering, check the listing to confirm against your exact model year.
Step 2: Clean and prep the surface
Wash the boot lid thoroughly and dry it completely. Wipe the mounting area with isopropyl alcohol to remove all wax, polish and road grime, this is essential for a strong, lasting bond.
Step 3: Mask and mark your position
Use masking tape either side to mark a level line, measuring from the same reference points on both sides so the spoiler sits perfectly central.
Step 4: Dry fit before you commit
Offer the spoiler up without removing the adhesive backing. Check it sits flush and level within your marked guides before going any further, this is the step that catches alignment issues before anything becomes permanent.
Step 5: Bond and secure
Remove the adhesive backing and, working from the centre outward, press the spoiler firmly into place within your marked guides. Apply firm, even pressure along the full width for at least 60 seconds and allow the adhesive to cure fully before driving at speed.
Common mistakes to avoid
- Not accounting for the curve of the boot lid when marking guide lines, leading to a spoiler that sits proud at one end
- Skipping the IPA wipe down, residue is the top cause of a spoiler lifting
- Fitting in cold weather without warming the adhesive or panel first
- Not measuring from matching reference points on both sides, leading to a spoiler that looks slightly off centre
- Washing the car or using a jet wash within the first 24 to 48 hours while the adhesive cures
