Jeremy Sanders42 said:McLaren have halted work on a new suspension system after Formula One's governing body warned teams that anything that changed a car's ride height between qualifying and the race was illegal.
"We've had to change some of the things we're doing. Basically we had a system we were working on, and we've now suspended that," engineering director Paddy Lowe said.
He said the MP4-25 Cars used by World champion Jenson Button and Lewis Hamilton in this weekend's Chinese Grand Prix would have som aerodynamic improvements but no other changes.
McLaren are second in the championship after three races, 10 points behind Ferrari.
The FIA wrote to all teams last week to clarify the rules after questions were raised about the suspension systems on some cars.
McLaren boss Martin Whitmarsh had said that his team were hoping to have a new system in place for Shanghai after noticing that some cars, notably Red Bull, appeared to be running lower to the ground than expected when light on fuel in qualifying.
Red Bull, one-two winners in Malaysia on April 4, have welcomed the FIA clarification and said their car will be the same in China as at previous races.
McLaren has put a stop to their development of a new system following a warning from the Formula One governing bodyβstating that any modification altering a car's ride height between qualifying sessions and the actual race is strictly against the rules.
"We've had to change some of the things we're doing. Basically we had a system we were working on, and we've now suspended that," noted engineering director Paddy Lowe.
He mentioned that the MP4-25 Cars used by World champion Jenson Button and Lewis Hamilton in this weekend's Chinese Grand Prix would have som aerodynamic improvements but no other changes.
Currently, McLaren are sitting in second place in the championship standings after three races, trailing Ferrari by 10 points.
Last week, the FIA sent out a memo to all teams to clarify the regulations after several questions surfaced regarding the suspension setups on certain cars.
McLaren boss Martin Whitmarsh had previously mentioned that the team was aiming to roll out a new system for Shanghaiβthis came after they observed that some competitors, specifically Red Bull, seemed to be running much closer to the track than anticipated during qualifying when running on lighter fuel loads.
Red Bull, who dominated with a one-two finish in Malaysia on April 4, expressed their approval of the FIA's clarification and confirmed their car setup in China will remain identical to what they've run in previous races.
