18" APEX FL-5 BMW 5x120mm Wheel

The FL-5 is our only wheel to feature dual flow forming. This means both the barrel and the front outer lip are formed using high-pressure rollers to improve their mechanical properties and maximize strength and stiffness. It allows us to use less material and reduce weight without sacrificing strength.

One of the most prominent features of the FL-5 is its advanced "I"-beam spoke machining. Any excess material that doesn’t add strength is carved out from the sides of the spokes using a precision CNC ball cutter. This process is often deemed cost-prohibitive by others, but for performance without compromise we believe it's essential.

The inner lip is the most vulnerable part of a wheel because it has no spokes for support. Our Flow Formed Evolution line adds more material to this high-impact area as an extra layer of protection against track berms, potholes, and whatever else the road may throw at you.

Wheels with a lip are notorious for having terrible multi-piston caliper clearance. The FL-5’s curved spokes were designed based on countless factory and aftermarket brake models. The spokes wrap around most calipers without sacrificing the FL-5's beautiful lip.

We conducted extensive Finite Element Analysis (FEA) to reinforce high-stress areas and to remove material where it didn’t improve strength. The result is a wheel that is exceptionally light without the strength compromises found on typical lightweight wheels.²

Track wheels need track tools. Don’t settle for wheels that require undersized tuner lugs or thin walled sockets. All APEX wheels accommodate over-sized race lugs and impact sockets to make swapping wheels lightning fast.

The FL-5 is finished using a multi-stage liquid paint over a powder coated base coat. This coating process leaves lug holes, center bores and mounting pads untouched, which ensures proper fit and torque values.

All APEX Flow Formed wheels meet or meaningfully exceed JWL load rating requirements. Some manufacturers don't meet the minimum requirements, yet still claim to be compliant. Always compare load ratings to ensure you aren’t sacrificing critical strength for a slightly lighter wheel.

The VIA is an independent wheel testing and auditing agency similar to TÜV. Many companies falsely claim their wheels have been certified, and even use the VIA stamp without permission. Our Flow Formed wheels have been certified, and we provide the registration numbers for every wheel. Protect yourself. Demand registration numbers from manufacturers.
