Doing all the work are the massive Pirelli PZero tires, sized at 305/675-18. This tire apparently came from the right rear, and the outer wear and lack of OPR (other people's rubber) say their efforts to engage the rear tires are reasonably effective.
Moving inside, the K-PAX fabricated cage is surprisingly simple and minimal as far as extra bracing and triangulation go when compared to many World Challenge racecars. The tubular subframes and wheel well reinforcement probably go a long way towards improving chassis rigidity. Volvo's legendary crash protection probably make adding extra bracing unnecessary.
We were actually somewhat surprised that the roll cage's forward legs did not follow the A-pillar more closely, but the shallow angle of the windshield probably would make those bars too likely to just collapse in a rollover. The kickers going forward penetrate the firewall and connect to the strut towers. Dashboards are required per the rulebook, so K-PAX made one out of CF.
Randy's perch is all business. The carbon/kevlar Racetech seat, 6 point harness and side nets work together to keep him in place under the most extreme conditions. The tank at bottom right is the radiator sprayer reservoir.
