HQ Holden Racing brakes.
HQ racing is deliberately tightly controlled — the cars are near-identical, which pushes the racing onto the driver and the setup details you're still allowed to touch. Brakes are one of them: the category mandates the standard cast-iron front caliper and ventilated disc, but friction material is free.
Know your caliper, not your car.
These are the caliper families HQ Holden Racing cars run. Pick yours to see every brand and compound we can supply for it, with the manufacturers’ published operating temperatures side by side.
What to run, and why.
Because the caliper and disc are fixed, a race compound is the legal upgrade that actually changes the car. Look for consistency across a full race distance rather than peak friction.
Every caliper page lists the compounds we stock for that shape with the manufacturer’s own published operating temperature and friction figures — so you can match the pad to your session length and car weight instead of guessing from a product name. Not sure? Ask BuildBot with your car, class and typical race length, or email sales@tracktheory.com.au.
The HQ Racing technical regulations specify the standard PBR or Girlock cast-iron front caliper with a 276mm ventilated disc and drum rears, and state that friction lining type is free. Always confirm the current year's regulations with your category — compliance sits with you and your scrutineer.
