We are proud to introduce our most aggressively styled diffuser yet, the Varis Style Carbon Fiber Rear Diffuser with Undertray. This rear diffuser and undertray combo is sure to set off the rear appearance of your F80 M3 or F82/F83 M4. This item fits all 2015-2020 M3 and M4 applications. This item will come as a 2 piece kit, the diffuser AND the undertray – Both of which will be crafted from 2×2 carbon fiber and completed with a high gloss clearcoat. This clearcoat doesn’t only make the diffuser look great, but it also help to protect it from all the harsh elements out there on the road. As with all of our items, installation is 100% bolt on and requires no special modifications or cutting into your M3/M4 (Other than screws to secure the undertray). It will include all necessary brackets and hardware required for installation.
Installation
We highly recommend professional installation for this F8x M3 and M4 Varis style rear diffuser. It is a very large piece and requires several people and a lift to get it installed. If you are local to us please set up an appointment to have us install it. All the hareware will be included but if you have any questions be urge you to contact us and we can get you in touch with one of install techs.
