Each diffuser fin is reversible giving you 2 style choices to choose from. Diffuser fins are also slotted which gives you the flexibility to set the depth. Pull them out for an aggressive look or push them in to keep it neat and tighten when done.
Diffuser fin profiles can be set before or after installation, adjustment can be done on the car by loosening a few fasteners (refer to fitting diagram).
This 8-piece set includes a pair of adjustable diffuser winglets and a pair of spats for everything to mount to.
Everything is pre-drilled and there is no need to remove the rear bumper for installation, only basic tools and knowledge is required.

Why do we use Polyethylene Composite for Flow Designs Splitters?
Strong, impact resistant, doesn't corrode or chip, and has excellent abrasion resistance (say… from scraping on driveways and road all the time?)
Carbon Fibre is better, isn’t it?
As strong and light as Carbon fiber is, it CRACKS on impact or when under load and/or stress. Clearcoat will eventually fade & crack and become undesirable.Install Instructions (PDF)
How Strong Are Our Splitters?
HOW IS YOUR SPLITTER SO STRONG?
Each splitter is developed to become an integral part of your stock body kit, giving it unrivalled rigidity and strength so it can absorb scrapes and protect your bumper.

WHAT ABOUT CARBON FIBRE?
As strong and light as carbon fibre is, it cracks on impact or when under load and/or stress. Clearcoat will eventually fade or crack, becoming undesirable.
USE OF ABS PLASTIC
Please note that although all our precision-made ABS accessories are extremely strong and durable, they do not hold the same shatterproof label as our 10mm thick polyethylene composite splitters. The accessories are manufactured in ABS with the intention that they will be lighter, bolt-on attachments that will improve aesthetics and are easily replaceable if they become damaged from varying road conditions.
