Arrow McLaren and Greene Tweed have co-engineered a lightweight anti-roll bar lever for INDYCAR race cars using Greene Tweed's Xycomp DLF thermoplastic composite. The redesigned suspension component reduces weight by 64 grams per car whilst maintaining strength and reliability required for elite racing. The component, which helps control chassis roll during high-speed cornering, was transitioned from 7075 aluminium billet to the thermoplastic composite material. Greene Tweed worked closely with Arrow McLaren's engineering team to evaluate performance requirements, geometry and manufacturing approaches. The new anti-roll bar levers were first introduced on Nolan Siegel's No. 6 car at Barber Motorsports Park and have since been implemented across all Arrow McLaren vehicles. The project also reduced internal development workload for Arrow McLaren's engineering and production teams.

Zak Brown confirmed the completion of McLaren Racing's stake sale to Mumtalakat and CYVN, valuing the company at $4.1 billion. The sale gives the two entities 100% ownership of McLaren Racing. Brown highlighted the sport's growth, citing increased fan engagement and sponsorships. He dismissed claims that valuations have peaked, noting the sport's potential for further growth with strong demand for races and competitive dynamics.
