Modifieds

These cars utilize a factory frame in the front and the rest of the chassis is fabricated out of tubing. The front suspension is similar to a street stock. Modifieds use a rear suspension that has been engineered for traction and faster corner handling. The engine rules for this class are less restrictive, which provides for more variables for maximizing horsepower and torque.

The boxy bodies are built out of sheet aluminum to conform to the class rules. That is why all these cars look very similar.

Aldy's specializes in Jet modified rolling chassis. However, race ready cars are available.

Price: Range dependent on options for chassis, rear suspension, engine and components.

$12,000 - $ 17,000
