Tarek’s widebody BMW M4, featuring Serious Innovations’ yellow-tank hardline trunk installation, black suede finish and documented audio upgrades.

The build story

Tarek’s BMW M4 combines a widebody exterior with a carefully finished air-system installation. Known on Instagram as @strictly_stance, Tarek brought the car to Serious Innovations for a clean hardline trunk layout.

The documented shop work centers on a yellow powder-coated 3-gallon seamless air tank, gloss-black straps and hardlines, and stainless steel compression fittings. Black suede finishes the trunk.

The shop’s September 2025 feature also records a Morel speaker package and a unit described as “MatchUp 10 DSP.” Exact audio model numbers and speaker locations still need confirmation.

A February 2020 video by Tremond Director Truesdale identifies an earlier version of Tarek’s M4 as a Varis widebody on Rotiform SIX wheels. These are historical details, not confirmation of the configuration shown in the later shop photographs. The model year, current wheel dimensions, suspension equipment and complete performance specifications remain unconfirmed.
