Build smarter

Tune it for Whanganui

The Drews Ave course isn’t straight. You’ll need legitimate steering, confident brakes, and a kart that can recover after the chicane.

Read the full build guide

Steering Geometry

Double-check Ackermann steering for tight Drews Ave hairpins and include a steering stop.

Brake Confidence

Hydraulic bike disks or robust scrub brakes are mandatory—finish chute requires a full stop.

Driver Fit

Harness or lap-belt recommended; drivers must demonstrate they can exit within 10 seconds.

Visibility

Add high-contrast numbers on both sides and the nose cone for marshal visibility.

Free for spectators

Hilltop festival vibes

Bring the whānau, claim a haybale and soak up Vintage Weekend. Food, music, and retro fun all day long.

Coffee & Eats

Local roasters, JJ Roofing Running of the Balls lunch break, and food trucks all day.

Entertainment

Live DJ, MC banter, and pop-up retro games to keep the hill buzzing between heats.

Best Vantage

Stake out the terraced gardens or grab a haybale near the chicane for serious thrills.

Accessibility

Accessible viewing is signposted near the top of Drews Ave with mobility parking off Taupō Quay. Volunteers are on hand to assist with seating and shade.
