Q & A

What's in the Box

Advanced technology allows the F33i caliper to outperform the competition. Four unique, locking sleeves increase the caliper's structural integrity and resistance to distortion. Lower pedal effort, less brake pad taper, and more consistent lap times make this caliper the winner's choice. Machined from billet 6061-T6 aluminum, these calipers are the hot set-up for todays serious racer.

  • Innovative internal construction locks together the caliper halves for increased rigidity; extra rigidity provides more consistent stopping performance and less brake pad taper
  • Ultra-high temperature resistant square-cut seals resist damage caused from heat and wear
  • Billet-machined 6061-T6 aluminum construction provides maximum strength
  • Bore Diameter: 1.38"
  • Disc Width: 0.81"

Note: Replaces DL type calipers, 5.25" mounting centers.  Commonly used on late models or sprint cars.

AFCO 1251-1000 C1 Pads, F33i/DL/Mini Grand National
                        

The C1 brake pad compound was designed and developed to meet the braking needs of medium to high temperature racing applications. As brake system temperatures quickly increase and decrease, C1 provides consistent performance while remaining fade resistant. C1 has proven to be extremely rotor friendly and provides exceptional pad life without requiring lengthy pad break-in (bedding) procedures.

C1 is widely used in dirt track racing and is the ultimate pad for all medium temperature applications. Recommended temperature use: 400-900 degrees.  

  • High torque with excellent control qualities
  • User friendly/easy break-in
  • Exceptional pad and rotor wear
  • Made in the U.S.A.
  • Sold as a set of 4

Tech Tip:  Only use full metallic pads on coated rotors.
