ROAD TO NATIONALS β€” JAI PHILP #21 With over 25 ye ROAD TO NATIONALS β€” JAI PHILP #21

With over 25 years of racing and driver training experience at Motormall Wanneroo Raceway, Jai Philp is excited to be returning to Improved Production Racing after a seven-year absence.

His 2014 Toyota 86 GTS is no stranger to 3J racing either, having competed at the previous Nationals held at Wanneroo Raceway in 2017. The Philp Motorsport 86 was also one of the earliest β€” if not the first β€” IPRA Toyota 86s in the country. Built as soon as the platform became eligible, the car was raced successfully for several seasons before being sold in 2019.

Fast forward to 2025 and Jai purchased the car back, bringing it home and giving it a completely new chapter. Gone is the previous Castrol livery, with the 86 now transformed into part of the Motormall Motorsport family and proudly representing the brand.

Since returning, the car has already been back in competition, placing second overall in the 2025/26 Tarmac West Rallysprint Series at Kwinana Motorplex.

Now, seven years on from Jai’s last Improved Production campaign β€” and nine years since this very car lined up at a Nationals at Wanneroo β€” both driver and car are heading back to where it all started.

Jai Philp. Toyota 86. #21. Back in Improved Production and ready for the 2026 Bridgestone Improved Production Nationals. #roadtinationals #iprawa @philpmotorsport @motormallmotorsport

ROAD TO NATIONALS β€” JACK CLOHESSY #222 For Jack C ROAD TO NATIONALS β€” JACK CLOHESSY #222

For Jack Clohessy, racing started young.

Go-kart practice began at just five years old, with racing from six at Wundowie. From there, weekends were basically spoken for β€” if the family wasn’t racing, they were practising.

For his 13th birthday, Jack received a Hyundai and made the move to bitumen. Plenty of laps followed at Wanneroo Raceway before he was old enough to race, and from 14 he spent a number of years competing in Excels, eventually taking 2nd at the Excel National Titles here in WA.

After stepping away from motorsport for a period to focus on other sport, Jack is back behind the wheel β€” this time in Improved Production.

And he’s returned in a pretty special piece of racing history.

Car #222 is the ex–Kevin Ledger Subaru WRX, an iconic Improved Production car that Jack describes simply as a great car to drive β€” and a very quick one.

Now the focus turns to October.

Jack is looking forward to getting back amongst a national field, lining up against competitors from around Australia and seeing what #222 can do when the 2026 Bridgestone Improved Production Nationals hit Wanneroo Raceway.

From karting at six, to Excels, a national podium and now Improved Production β€” Jack Clohessy is back racing, and ready for Nationals. 🏁 #iprawa #roadtonationals

ROAD TO NATIONALS β€” BRETT SHERRIFF Brett’s racing ROAD TO NATIONALS β€” BRETT SHERRIFF

Brett’s racing career has seen him compete successfully across several different categories in WA, claiming two WA Sports Sedan State Championships before going on to become a three-time WA Excel State Champion.

In late 2025, Brett added Saloon Cars to the mix, campaigning his AU Falcon and quickly finding himself at the pointy end of the field in his first year in the category. He continues to race the Falcon alongside his Improved Production commitments.

For the Nationals, the focus turns to a very different machine β€” a Mazda RX-3 powered by a 13B Bridgeport rotary and competing in Improved Production Under 3 Litre.

With just one race meeting under his belt in the RX-3, there’s still plenty to learn β€” but October is when it all counts.

The 2026 Bridgestone Improved Production Nationals are coming to Wanneroo, and Brett will be throwing everything at the Under 3 Litre battle. Get trackside and come see what #27 and the little rotary can do when the best Improved Production cars from around Australia hit WA.

WHAT IS IMPROVED PRODUCTION RACING? 🏁 Improved Pr WHAT IS IMPROVED PRODUCTION RACING? 🏁

Improved Production is a production-based racing category run under Motorsport Australia’s Group 3J regulations.

The concept is simple: start with a production car and modify it within a controlled set of technical regulations covering areas such as engines, suspension, brakes, wheels, tyres, safety equipment and driveline.

Here in WA, Improved Production features a huge mix of cars including Civics, Corollas, Escorts, RX-7s, Toranas, Commodores, Falcons and plenty more.

The WA capacity classes are:

β€’ Under 1600cc
β€’ 1601–2000cc
β€’ 2001–3000cc
β€’ 3001–6000cc

That means naturally aspirated, turbocharged, rotary, four-cylinder, six-cylinder and V8 powered cars can all race within the same category, separated by engine capacity.

Older eligible cars can also compete under Group 3J Classic regulations, giving the category a mix of modern and historic machinery on the same grid.

Improved Production is not a one-make or control-car category. Different manufacturers, engine configurations, chassis layouts and build philosophies all compete under the same technical framework.

Across a WA race meeting, drivers compete for class results as well as outright positions, creating several separate races within the one field.

That variety has been a major part of Improved Production from the beginning β€” production-based cars, heavily developed for circuit racing, with a broad mix of machinery across every grid.

That’s Improved Production Racing. #iprawa #roadtonationals #circuitracingaustralia #motorsportwa
