Sergio Perez believes that Force India is making "too many compromises" with their 2018 car. The team that had been renowned as the best 'pound-for-pound' competitor on the grid has slipped back from where they thought they would be this season.
Speaking to Motorsport.com, Perez said that the team were struggling with aero performance mostly that have led to unwanted compromises with set up.
“It’s downforce, basically, to be able to balance our car better.
“We’re struggling quite a bit with downforce and therefore we need to make too many compromises on the balance.
“When you see Barcelona, or other races, we’re still lacking a bit. It will be interesting to see where we are around Monaco.
“It’s really close between Haas, Renault, McLaren and ourselves. Whatever we can gain on a weekend can relate straight away to the final result.
“We’re looking for small margins. I still think at the moment we’re at the back of that group.”
