The FDF x Adam LZ Angle Kit

After two full seasons of development and feedback, we’ve been refining a setup built specifically around how Adam LZ drives and what he demands out of the car. This latest version of his kit brings together a series of small but very intentional changes, all centered around maximizing driver feedback and control.

One of the biggest factors shaping this kit is the amount of camber, caster, and KPI Adam runs. These values are far beyond what most traditional setups call for, and once you start pushing into that range, even the smallest geometry changes begin to matter. To support that, we made adjustments to the bearing angles to ensure everything operates smoothly without putting unnecessary stress on the components, even at those extremes.

Looking at the front lower arms, they’re very close to our standard E46 design, but with subtle changes that make a big difference. Because of how much caster he runs, pushing into the 9.5 to 10-degree range, we tightened up the bend in the arm to maintain proper positioning and clearance under load. On top of that, we built in a 10-degree kick at the end of the arm, angled in a way that helps correct camber while also working with the rearward shift created by that caster.

The goal with this setup isn’t to create something that’s broadly adjustable or generalized, it’s to replicate exactly what Adam runs. That means when this kit is installed, it’s designed to deliver the same steering response, the same level of feedback, and the same overall feel that he relies on when competing.

We also locked the Ackermann adjustment into the most positive position, which is where he runs it. Combined with the rest of the geometry (trail, roll center, and offsets), it creates a steering system that feeds significantly more information back to the driver. The best way to describe it is like turning up the force feedback on a sim setup, except this is happening mechanically through the chassis and steering system in real time.

His use of caster plates also plays a major role in how the kit performs. Instead of following more traditional setups, he runs them fully rearward while also pulling camber inward, increasing KPI even further. It’s not the conventional approach, but it’s one that results in a very direct and responsive car, especially when everything is working together.

While the front setup is highly specific to his driving style, the rear design focuses more on strength, reliability, and adjustability. The trailing arm is based on an OEM M3 layout, but improved in key areas where the factory components tend to fall short. We integrated mounts for his Wilwood brake setup directly into the design, eliminated unnecessary hardware, and retained the OEM shock mounting position for consistency.

We also reworked the toe adjustment system to make it easier to fine-tune. Instead of relying entirely on sliding components back and forth, the design allows for shimming, which gives more precise control.

Another important consideration with a setup like this is how changes in one area affect everything else. With the amount of caster being run, the relationship between the tie rod and control arm shifts significantly. To compensate for that, we built in bump steer adjustment so the geometry stays balanced and predictable. It’s one of those details that plays a huge role in how stable and consistent the car feels when it’s being pushed.

What all of this comes down to is a kit that’s built around a very specific philosophy. Instead of dialing things back for comfort or ease of use, this setup leans fully into maximizing feedback and performance. Every adjustment, every angle, and every design choice is made to support that goal.

The end result is a system that closely mirrors exactly what Adam runs on his own car, giving the driver as much information as possible and allowing for a level of control that’s hard to achieve with more conventional setups.
