Audi A4 B9 Body Kits and Tuning Parts

For the Audi A4 B9 2015–2024 (Sedan and Avant), there is model-specific tuning in RS4 style: RS-Style and S-Style front bumpers, an RS4-Style body kit set, complete rear bumper assembly, hood, grilles, rear diffusers with exhaust tips, lip splitters, spoilers and side skirts, as well as floor mats, window deflectors, mud flaps, chrome trims, mirror caps, roof cross bars, and steering wheels. Front and rear parts are split into pre-facelift 2015–2019 and facelift 2019–2024 — they are not interchangeable; the years are listed in each product name.

Which RS4-style body kit fits the A4 B9: pre-facelift or facelift?

The largest sections are GT Tuning body kits and bumpers. For 2015–2019 there is an RS-Style front bumper, its “for radars” version (for cars with bumper sensors), and an S-Style bumper; for 2019–2024 — an RS-Style front bumper, a complete rear bumper assembly, and the full RS4-Style body kit set. All parts are plastic, mount to factory locations, and are paint-ready: first test-fit and set gaps, then paint. You can install the body kit at the DD Tuning network of certified service centers — your manager will suggest the nearest one. For Allroad, RS-Style bumper compatibility is confirmed separately: mounting points may differ. For the front end: the RS-Style hood (2015–2019, metal), radiator grilles (RS-style Quattro is also compatible with the S-Line Sedan 2016–2019; rings and license plate mount as shown in the photos), and RS-Style fog light grilles (2 pcs), separate for each generation.

Lips, diffusers, spoilers and side skirts: plastic or carbon?

Lip splitters: DPT V-1 for the S-Line bumper 2015–2019 (gloss black, 174 cm) and V-1, V-2, V-3 for 2019–2024 — ABS plastic mounted with windshield adhesive/sealant, which is not included. Rear diffusers: for 2015–2019 — S-Style and DPT (148 cm) for the standard bumper; for 2019–2024 — RS-Style V-1 and V-2 with exhaust tips, plus rear diffuser add-ons. Spoilers: DPT in gloss black (121 cm) and eight carbon options for the Sedan; side skirts DPT — a pair of 194 cm, paint-ready. Genuine carbon is in the carbon trim section: lips, diffusers and fog light trims for Base and S-Line Sedan, RS4 Avant parts, and mirror covers.

Which floor mats, steering wheels and interior trims are available?

Cabin floor mats: EVA Digital Designs — 4 pcs in five colors, Stingray 3D polyurethane (5 pcs), Stingray and Carsuit rubber mats, Classic, Premium and Deluxe textile mats. Trunk mats are separate for Sedan and Avant: Carsuit, Stingray 3D, textile, and EVA in six colors. Also available: steering wheels S-Style and R8-Style, and door sill plates Omsa Line for 4 doors.

Chrome, mirrors, deflectors, mud flaps, roof — what fits the Sedan and what fits the Avant?

RS-Look DPT mirror caps are installed over the factory covers — no need to remove them; carbon covers V1 and V2 are also available. Stainless steel chrome trims: Carmos trunk edge trim (confirm body type in the product page), Omsa Line license plate strip — for Sedan, Carmos rear bumper protector 99 × 8 cm — for Avant. HIC window deflectors are separate for Sedan and Avant, 4 pcs. Premium mud flaps: 4 pcs for factory locations, separate for 2015–2019 and 2019–2024; the second set also fits the Avant 2022. For the Avant roof — cross bars for standard and flush rails; for the Sedan’s smooth roof — a pair of Oluksuz V4. Badges and lettering are also available.

How to choose the right part for your A4 B9

1. Years: 2015–2019 pre-facelift, 2019–2024 facelift — front and rear parts are not interchangeable.
2. Bumper: Base, S-Line, or an already installed RS-style bumper use different add-ons; if the bumper was replaced, go by the bumper, not the model year.
3. Body type and trim in the product page: Sedan and Avant differ in deflectors, trunk mats, and rear trims; adhesive for lips and side skirts is purchased separately. Not sure? Send the manager a photo of the front or rear end.
