With the BMW M340i's engine performance and durability projects well underway, our team turned their focus to the exterior, aiming to craft a look that matched the car's aggressive new capabilities. The goal was to transform the vehicle into a cohesive, high-performance daily driver with bespoke styling—a street-legal, track-ready sports sedan. To bring this vision to life, HPS partnered with several leading brands in the aftermarket industry, starting with the car's posture and handling.
A KW V3 coil over kit was installed, providing the necessary adjustability for both rebound and compression dampening via its dual level valves. This new lowered stance was beautifully complemented by a striking set of 19-inch Rays 57CR 5spoke wheels finished in Gunblue 2. To ensure maximum grip and stability in all conditions, the larger, wider wheels were wrapped in high-performance Toyo Tires Proxes Sport A/S tires, sized 245/35/19 in the front and 275/30/19 in the rear. For ease of installation, our team opted to add a 14x1.25 to 14x1.5 stud conversion kit to mount the wheels and secure them with Muteki HR50 14x1.5 lug nuts.
The cosmetic transformation was completed with sleek Suvneer aero components, including the CS Designed Aluminum Hood, MP Designed G20 Carbon Fiber Side Skirt Extensions, G20 LCI SM Carbon Fiber Front Lip, and carbon fiber side mirror covers. A standout choice was the R1 Designed Carbon Fiber Trunk Spoiler, selected specifically because it combines aggressive aesthetics with lightweight performance.
Inside, the M340i received performance and safety upgrades with high-performance Sparco QRT Performance racing seats, finished in leather to match the car's interior. These seats were installed using Sparco’s slider bracket and side mounts, complemented by Sparco COMP H-2 PD 6PT 2" harnesses for track security. Small, but impactful interior details included carbon fiber steering wheel shifter paddles, chosen for their length over stock to offer better reach and comfort.
Finally, the team ensured a clean, intentional look by keeping the car's graphics minimal but impactful, designed by our friend Young Tea to complement the car's sleek lines and the Gunblue 2 wheels, completing the transition into a truly bespoke machine that embodies engineering excellence and aggressive style.
