Performance upgrades to the braking system.When I ordered the Atom, four brake option levels were available: base, sport, track, and race. I had originally chosen the sport option, which included 4-piston Wilwood fixed calipers front, and single-piston PBR floating calipers rear, both with single piece 10.3" rotors. This album shows the upgrade to the track option.

parts for rear upgrade to track option - rear brakes - sport option (old)
sport option rear included single-piston floating PBR calipers and 10.3" rotors - rear comparison
new on left, old on right - note the pad size difference - Hawk pads
Wilwood PolyMatrix pads are used on the street, but I'll be trying out Hawk DTC70 pads for the track on all 4 corners - rear done
on the rear, new 4-piston fixed-mount Wilwood calipers with 2-piece 11" rotors - rear gear - view from front
pulling the cotter pin is all that it takes to swap pads - Wilwood pad change
