I don't think he's using a suspension that was banned, they would have used it on both cars & we wouldn't have seen Ricciardo struggle for pace (besides any engine issues). I think he had the car dialled in to the circuit perfectly, combined with a great downforce car, clear air, and durable tyres meant he had some incredible pace.
Budkowski won't be active with Renault till March next year, by which time the 2019 car is the only time he's going to have some level of influence. Power units will have moved on majorly by then. It'll be a political story next year, and nothing more.
