Perth Motorplex High Limit International stuns with $110K showdown
The 2025 High Limit International at Perth Motorplex is a three-night sprint car gauntlet running Dec. 28–30, with a record AUD $110,000-to-win A-Main crowning the finale. More than 40 sprint cars, including a strong American contingent and Australia’s best, will contest preliminary heats, dashes, B-mains and last-chance races across Sunday and Monday to earn positions for Tuesday’s 40-lap main event. Night one opens with qualifying draws, heat races, group dashes and preliminary features (including a $15,000 prelim payout), while night two tightens the field through semifinals, additional heats and last-chance qualifiers to set the top 24 for the A-Main. Support categories and a fireworks finale will accompany the headline sprint car action on the final night.
Qualifying begins the sequence by assigning pill positions and producing fast laps that influence starting spots: the quickest qualifier in each group is inverted to fourth in their eight-car heat, encouraging overtakes and mixed lineups. Heat advancement is straightforward for many — the top five from each of four heats, plus heat winners and the four fastest non-winners, progress directly to the 30-lap features — while the remainder battle through B-mains and last-chance races for the remaining transfer spots. Dashes are short seven-lap sprints with a redraw element that injects luck and pressure; good preliminary form can help drivers avoid high-risk dash situations.
A cumulative points structure across the first two nights decides Tuesday’s starting order and which drivers make the A-Main. Points come from qualifying laps, heat results and features, with passing points (five points per position gained in heats) rewarding aggressive moves. Feature finishes are weighted — for example, first place nets 40 points with subsequent positions decreasing in five-point increments — and totals from Sunday and Monday determine seating for Tuesday’s heats. That system prizes consistency across sessions: a single fast lap or lone heat win won’t erase poor results elsewhere, so steady performance, smart racecraft and mechanical reliability are essential to reach the big payday.
The format intentionally filters out one-off flukes and highlights drivers who can adapt to a changing dirt track and sustain results over three nights. Track evolution, tire management and clean passes are emphasized as teams jockey for position while avoiding mechanical issues that could force a late requalification. In short, the High Limit International is a high-stakes, multi-night test of speed, strategy and resilience — with a massive AUD $110,000 prize ensuring every lap counts.
