NASCAR Classic Series FIRST Race: Vintage Stock Cars Officially Home! (VIR Road Course)

What happens here

The braking system for the car incorporates rotors that are similar in size and style to those historically used at tracks like Martinsville. However, the calipers are newer versions, reflecting advancements in brake technology over time. The rear end is crucial for road course performance, so a specialized road course housing is utilized, featuring approximately 1.5 degrees of negative camber on each side. This setup, often found in 'short track' configurations, improves cornering grip and stability. Additionally, a small amount of toe-in (around 1/8 inch total) is set in the rear for further stability.

Goal: Optimize braking performance and rear axle geometry for road course conditions.

Tools and materials

  • Brake Calipers — Squeezing brake pads against rotors to create friction
  • Brake Rotors — Primary braking surface for heat dissipation and friction
  • Road Course Rear End Housing — A specialized rear axle assembly with built-in or adjustable negative camber

started them in ' 07 right you know are these the same brakes they ran Martinsville with um no no the brakes uh the rotor sizes and all that are the same uh the caliper is probably just a little bit newer version calber um you know of course always with the brake people they're always coming out with something new um but uh so pretty much the same style of stuff same size [Applause]
