Reflecting on the decision to initially forge their own path, Bayer admitted that it was a mistake and something the team will learn from going forward.
Red Bull decision proved costly
"The initial decision to go our own way with those critical parts simply was an error, and the people [who made the decision] back then are not with us anymore," he told Autosport.
"I guess engineers always have plenty of arguments why you should do certain things, but I think everybody in the paddock understood now that with this new regulation change and the new downforce pattern, which is so reliant on the floor, the suspension is the next most important thing.
"You've got the floor and then you've got the suspension. If those two don't work together, you might as well not go out."
"I guess that's the big learning for us for this year," he added when asked if the team were trying to out-think Red Bull.
"But at the same time, what is tricky for us as a customer is you get a piece, but you have to make that piece work and it's very difficult.
"Look at some other teams who have hired ex-Red Bull aerodynamicists and engineers, they made some quick gains but then constant development is not as easy as it looks."
