Choosing the best Audi A5 body kit starts with one thing: making sure the parts actually fit your exact generation and bumper. For most owners, a front splitter is the easiest place to start, while a full front, side and rear setup gives the car a more complete, matched look. Just keep in mind that B8, B8.5 and B9 parts are designed differently, so they are not interchangeable.

Quick Picks

• B8 (2007–2011): Front splitter for a single change, full kit for a complete look
• B8.5 facelift (2011–2015): Facelift-specific splitter first, then matching lower-body parts
• B9 (2016–2019): Front splitter and side skirts as a middle step, full kit for the whole car

Which Audi A5 Generation Do You Have?

The A5 has three versions that matter for styling parts. Their bumpers and lower body lines differ, so the wrong part will not sit properly. S-Line, S5, Coupe and Sportback variants add further differences.

Audi A5 B8

The B8 is the original first-generation A5. KSB's early S-Line and S5 styling parts cover 2007–2011. A B8 front splitter follows the shape of that earlier bumper, and matching skirts and rear splitters carry the same lower line around the car.

Audi A5 B8.5 Facelift

The B8.5 is the facelifted B8, not a new generation. The facelift changed the front bumper profile, which is why KSB lists separate 2011–2015 parts. Many owners search for "A5 B8 splitter" when their car is actually a facelift, and a small bumper difference is enough to affect alignment and mounting.

Audi A5 B9

The B9 moved the A5 to the newer F5 platform, with sharper creases along the bonnet and flanks. KSB's B9 range covers 2016–2019 A5/S5 models. It includes front, side and rear parts plus a complete kit.

If you are unsure which version you have, compare your bumper with the product photos. Registration year helps, but it should not be your only check.

What Is Included in an Audi A5 Body Kit?

On the A5, a body kit usually means low-line styling rather than replacement bumpers. A complete kit typically has:

• a front splitter
• side skirts or side skirt extensions
• rear splitters or rear spats

The splitter lowers the look of the nose. The skirts continue that line along the sills, and the rear pieces finish it behind the doors. A rear splitter or spat is not the same as a full diffuser, so check what is actually supplied.

Best Audi A5 B8 Body Kit and Splitter Options

KSB offers a B8 front splitter, side skirts, rear splitters and a complete front-side-rear kit for the S-Line and S5.

A front splitter suits owners who want one noticeable change and a mostly standard car. A matching kit gives a bigger change, because the skirts and rear pieces repeat the same line. An aggressive front with a standard side and rear can look unbalanced, so a simpler splitter often suits a standard A5 better than the largest option.

Best Audi A5 B8.5 Facelift Body Kit and Splitter Options

Use only parts listed for the facelift bumper. A front splitter alone adds shape without making the car look heavily modified. Pairing it with matching lower-body parts gives a cleaner result from more angles.

Check the body style too. If a kit is listed for the Coupe, do not assume the rear parts fit a Sportback.

Best Audi A5 B9 Body Kit and Splitter Options

The B9 suits lower-body styling because its factory lines are already sharp.

B9 Front Splitter

This is the best starting point for most owners. It makes the biggest visual change from one part, and you do not have to commit to a full kit. KSB's B9 splitter fits 2016–2019 A5/S5 models and is made from gloss-black ABS.

B9 Front Splitter and Side Skirts

Side skirts carry the lower line along the sills, which gives a more finished look from the side and three-quarter angles. This is a good middle step if you are not ready for rear parts.

B9 Rear Splitters

Rear splitters add shape to the lower corners of the bumper. They are a smaller change than a diffuser, but they link the rear to the front splitter and skirts.

B9 Full Body Kit

Choose this if you already want matching styling all round. KSB's B9 kit combines the front splitter, side skirts and rear splitters in one set.

Audi A5 B8 vs B8.5 vs B9 Body Kits

The safest buying rule is straightforward: match the styling part to the actual bumper on the car, not simply to the Audi A5 name.

Should You Buy a Front Splitter or a Full Body Kit?

A front splitter is usually the better starting point if you want a noticeable change without modifying every side of the car.

It also makes sense if you are working to a smaller budget or planning the build in stages.

A full kit becomes more worthwhile when visual consistency matters. The front, side and rear pieces work together, so the car looks intentionally modified rather than having one isolated add-on.

If you prefer to build gradually, a sensible order is:

1. front splitter
2. side skirts
3. rear splitters
4. matching complete setup

There is nothing wrong with stopping after the first or second stage. The finished car should suit your taste rather than following a fixed modification checklist.

ABS, Carbon Fibre or Fibreglass?

Material deserves more attention than it often gets because a splitter sits close to the road and takes far more abuse than a spoiler or upper-body trim piece.

ABS Plastic

ABS is a common choice for road-going splitters and skirts because it is relatively light and has useful flexibility.

That matters on a daily-driven A5. Road debris, awkward ramps and occasional contact with a steep entrance are real-world concerns, particularly on cars driven throughout the UK.

KSB uses ABS across several of its current Audi A5 styling products.

Carbon Fibre

Genuine carbon fibre appeals to owners who want the exposed weave and low weight.

It is normally more expensive, though, so it tends to make the most sense on a build where carbon styling is already part of the overall theme.

Fibreglass

Fibreglass is also used for body styling, particularly on larger or custom pieces.

Quality varies considerably. On low-mounted parts, accurate moulding and a good fit are more important than simply choosing the cheapest material.

For a daily-use A5, a well-fitting, durable part is usually the better buy than a more dramatic component that is awkward to live with.

For a deeper look at this material choice, KSB also covers why ABS plastic is used for car styling.

Will an Audi A5 Splitter Reduce Ground Clearance?

Yes. A splitter reduces the effective clearance at the front edge of the car.

The amount varies with the splitter design and the ride height of the A5.

On a standard-height car, the change may be easy to live with. On a lowered car, the same splitter can become much more vulnerable to speed bumps, kerbs, steep driveways and multistorey car-park ramps.

A few habits help. Take sharp changes in road angle slowly, avoid driving straight into high kerbs and pay attention to the approach angle on steep entrances.

Ground clearance is worth thinking about before buying, not after the splitter has been fitted.

How Are Audi A5 Splitters and Body Kits Fitted?

Installation depends on the individual part.

Some front splitters use bolts or existing mounting areas, while side skirts and rear splitters may require screws or other mechanical fixings.

Whatever the setup, trial fitting matters.

Hold the part in position first and check the alignment from both sides of the car. Make sure the spacing looks even and that the component sits correctly against the bumper or sill before drilling or tightening permanent fixings.

Owners comfortable working with body trim may be able to fit some parts themselves. If the job involves drilling, lifting the vehicle or correcting uncertain alignment, professional fitting is the safer route.

KSB also has a dedicated guide explaining how to install car splitters.

How to Check Audi A5 Body Kit Fitment Before Buying

Run through these checks before placing the order:

1. Identify the generation: B8, B8.5 facelift or B9.
2. Check the model year stated on the product page.
3. Confirm the trim and bumper: standard A5, S-Line and S5 fitment may differ.
4. Check the body style: Coupe and Sportback parts should not automatically be treated as interchangeable.
5. Compare the product photographs with your own bumper.
6. Read the fitment description, including any exclusions.
7. Ask before ordering if there is still any doubt.

KSB has a separate guide on body kit fitment, which is useful if you are buying styling parts for the first time.

If you still cannot confirm your bumper or model compatibility, use the KSB contact page before ordering rather than guessing.

Common Audi A5 Body Kit Buying Mistakes

Most problems are preventable.

One of the most common is ordering an early B8 component for a B8.5 facelift because the owner has searched only by "Audi A5 B8". Another is assuming that anything labelled A5 or S5 will fit every bumper.

Body style gets overlooked as well, particularly with rear components.

Then there is ride height. A splitter may look perfect in product photos, but if the car is already low and regularly deals with tall speed bumps, a very deep design may become frustrating quite quickly.

Finally, check the design as a whole. Front splitters, side skirts and rear pieces do not have to come from a full kit, but they should look as though they belong together.

KSB's article on common body kit mistakes goes further into the problems worth avoiding before fitting anything.

Which Audi A5 Body Kit Is Right for You?

Start with fitment, then decide how far you want to change the car.

For a B8, use early-model-specific components. A B8.5 needs facelift-compatible parts, while a B9 requires styling made for the newer body and bumper design.

If you want one strong visual change, the front splitter is usually enough.

If you want the car to look consistent from the front, side and rear, a matching body kit is the better route.

The right setup is not necessarily the biggest one. On a well-kept Audi A5, good fitment, sensible proportions and a consistent finish usually make a stronger impression than adding as many exterior parts as possible.

FAQs

Will an Audi A5 B8 splitter fit a B8.5?

No. The B8.5 has a different front bumper profile. Use a splitter listed for your exact version.

How do I know if my Audi A5 is B8, B8.5 or B9?

Check the model year, then confirm it against your bumper and body shape. KSB lists B8 as 2007–2011, B8.5 as 2011–2015 and B9 as 2016–2019. If your car is near a changeover year, compare the bumper directly with the product photos.

Will an S-Line splitter fit a standard Audi A5?

Not reliably. Standard and S-Line bumpers can have different lower profiles and mounting points. Confirm compatibility with KSB before ordering.

Are Audi A5 Coupe and Sportback body kits the same?

Not always. Some front parts may share fitment, but rear and side parts often do not. Check that the listing names your body style.

Is ABS a good material for an Audi A5 splitter?

Yes. ABS is light and slightly flexible, so it copes well with small impacts, debris and steep entrances.

Does a front splitter reduce ground clearance?

Yes. It extends below the original bumper edge. The effect is bigger on lowered cars and on roads with steep driveways or large speed bumps.

Can I fit an Audi A5 splitter myself?

Possibly, if you are comfortable with trim and fixings and can safely access the underside. Trial-fit before drilling. Use a professional if alignment or mounting is unclear.

Is a full Audi A5 body kit better than a front splitter?

Neither is automatically better. A splitter is simpler for a front-end change. A full kit suits owners who want matching styling on the front, sides and rear.
