The A90 generation Supra already comes with a factory ducktail spoiler, so getting a clean line when adding or replacing it matters more than on most cars. This guide covers the fitting process for our Toyota Supra rear spoiler, supplied unpainted for the 2019 onward generation.
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)
- Access to a bodyshop if you plan to colour match before fitting
Step 1: Check your fitment and finish
Confirm you have the 2019 onward Supra before ordering. Since this spoiler is supplied unpainted, decide at this stage whether you want it colour matched, most owners get it painted and lacquered before fitting rather than after.
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 for the strongest possible bond.
Step 3: Mask and mark your position
Use masking tape either side of the boot lid 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 to the boot lid without removing the adhesive backing. Check it sits flush and level within your marked guides before going any further.
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
- Fitting before painting rather than after, most owners get a cleaner result having it colour matched first
- 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
FAQs
Do I need to drill any holes?
No, this spoiler is designed as a direct adhesive fit using the supplied tape and adhesive, no drilling is required.
Does it need to be painted before fitting?
It is supplied unpainted, so we would recommend having it colour matched and lacquered before fitting for the best finish.
Can I fit this myself, or should I get it professionally fitted?
Most owners fit this themselves in under an hour. If you are not confident working with automotive adhesives, we would always recommend a professional bodyshop or detailer.
