• The EM578 utilizes a jig-welded, GT-style tubular chassis. This perimeter space frame chassis:
• Combines maximum rigidity, strength, and safety with minimized weight
• Arranges many individual components into a series of triangulated stress members
• Distributes stress and strain throughout the entire chassis, not just "big" tubes or rails
• Note: some competitive chassis designs use only heavy main frame members with tabs and tubes tacked on to support the body, which is less rigid.

The overall effect is an extremely strong frame - our design advantage!

• Our chassis design protects you and your passenger, incorporating:
• Integrated roll hoops above the feet, legs and head to provide roll-over protection
• Large, reinforced side rails to protect in a side impact collision
• Front and rear impact cages designed to crush and breakaway in the event of a violent collision
• In addition to the standard seat belt anchor points, optional anchor points are provided for 5- or 6-point seat restraint systems

The EM578 is safe for the street AND when driven hard at the track!

• Our goal was to deliver a stable, responsive racing machine that is fun and exhilarating to drive!
• We achieved this goal with the EM578 through extensive research: 
• Studying many designs, both on the street and track
• Applying our engineering background and meticulous experimentation
• Measuring, clamping, and lasering many ideas to reach the final design
• The result: receive quick suspension response with very little bump steer (when you hit a big bump and the steering wheel gets yanked out of your hand). 

It's easy to fine tune the suspension to suit your driving purpose!

• A fixture holds the chassis, allowing us to align individual tubes for welding
• We use two different welding methods: 
• Some welding is accomplished using MIG equipment and techniques
• The most critical welds are placed using the TIG (or "Heliarc") method
• All joints are full welded and inspected for defects and quality
• The chassis is chemically cleaned, coated with epoxy-based primer, finished with high quality acrylic enamel paint

Powdercoating your EM578 chassis is an available option!

• First, the floor pan and underbody panels are bonded and riveted to the chassis
• Next, the fore and aft firewalls are affixed using the same technique
• Soon, the internals are ready for installation, including: 
• Brakes
• Fuel system
• Vents, hoses, and all other wiring
• Suddenly your EM578 begins to take shape! 

• Exactly what you would expect on a true racing machine
• Optimized handling through: 
• Tubular unequal length A-arms for both the front and rear suspensions
• A-arms allow the axis of the wheel to remain vertical as the wheels travel up and down
• Carrera coilover shock absorbers, front and rear
• Commonly used in racing
• Adjustabe ride stiffness, ride height, and rebound characteristics
• Fitted with large 1.5" diameter tubular adjustable swaybars
• Fast ratio steering rack with tilt steering column, coupled to forged ARCA front spindles
