TCR Australia and Toyota 86 race winner Ryan Casha will join the Porsche Michelin Sprint Challenge Australia Series with DNA Autosport in 2025. 

Casha, 20, was the 2023 Toyota champion and also scored a class podium finish in the Bathurst 6 Hour, before making his TCR Australia debut with Garry Rogers Motorsport last year.

That season delivered a race win at Queensland Raceway and sixth place in the championship in a strong year.

Casha switches to one-make Porsche racing this season and will join the Porsche Michelin Junior Program as part of his campaign with the Sydney-based DNA team.

“I’m overjoyed by the opportunity to reunite with the team we had so much success with in the Toyota 86 Series in 2023 and I’m eager to replicate that championship winning feeling again in 2025,” Casha said.

“This season will be exciting, as Porsche always host a strong depth of talent in Sprint Challenge and I’m keen to join the esteemed Porsche Michelin Junior Program.

“Last year was a great experience for myself and to be able to learn off the likes of Aaron Cameron in TCR Australia and work with our corporate partners like Valvoline to find success, made it enjoyable.

“However I felt like I needed a change heading into 2025 and DNA afforded me that option. I can’t thank Barry and Garry and the rest of the crew at GRM enough for what they did for me last year. Especially my engineer Timmi who really helped develop me as a driver and person over a short 12 months and to secure that race win at home with those boys was a feeling like no other.

“I’m more focused and prepared then ever to hunt those trophies down this season and will be doing everything I can to work with our partners to make it a memorable year.”

Casha’s livery and sponsor reveals will come in due course in the lead-up to the opening round of the series – to be held with the Shannons SpeedSeries at Phillip Island – in April.
