The widebody journey continues! In this second chapter of the Audi A6 Widebody Build, we dive into fine-tuning ride height, prepping for custom splitter fabrication, and establishing precise measurements that will define the rest of the build. Whether you’re into DIY bodywork or advanced fabrication, this video lays down foundational techniques for a symmetrical, professional result.

Refining the Bumper and Ride Height

The build kicks off with a look at a modified front bumper that needed adjustment. With plans for a large custom splitter, Sam trims the bottom edge of the bumper using a grinder to avoid excessive overhang. After rechecking the fitment and cleaning up previous bodywork, the bumper is reattached and marked for final trimming.

To prepare for precision work, Sam sets the air suspension to what he estimates as ride height. He carefully checks multiple points across the car with a tape measure — from the fender corners to the mirrors and rear taillights — to ensure level and square positioning on all sides.

Locking in True Ride Height with Custom Blocks

To avoid future inconsistencies while working on the widebody kit, Sam creates a clever solution using custom-cut wooden blocks:

• 4” blocks for the front jack points
• 4.5” blocks for the rear

By lifting the car and setting it down on these pre-measured blocks, the team creates a repeatable reference height that allows body panels and flares to be built from the ground up with confidence.

This technique ensures the car remains perfectly level while measuring and cutting body components — a critical detail when crafting widebody panels.

Measuring Track Width and Laying Out the Splitter

Sam then tackles a common question: How wide is the car now?

Using steel bars bumped up against the tires and a tape measure, he calculates the track width to be approximately 87 inches. With that number in hand, he begins laying the groundwork for the front splitter:

• Cuts an additional 4” blocks to use as support guides
• Lays down ¾” particle board to form the splitter’s base
• Uses blue tape to visually sketch out the curve
• Cuts one side with a jigsaw and mirrors it on the opposite side for perfect symmetry

After rounding off rough edges with a rotary sander, he locks the base in place with screws to ensure it doesn’t shift during the upcoming flare build.

Smart DIY Measuring and Template Tricks

Getting accurate measurements around curved panels can be tough — especially near tires. Sam shares a brilliant trick:

• He uses a hardboard template resting on the splitter and 4″ block
• Traces the tire outline with a permanent marker
• Cuts the outline with an air saw for clean, sharp edges

To fine-tune the shape, he builds a small jig from a wooden block and a permanent marker, helping him create perfect radiuses and mirrored curves. He even teases a tips and tricks video on making the tool.

These small tricks result in factory-looking lines with DIY simplicity.

What’s Coming Next

The video ends with the base of the splitter completed and perfectly positioned. Sam hints at what’s next: forming the widebody fender flares — a process that will be covered in full detail in the next episode.
