Red Bull are unlikely to be using their Kers power boost system in Sunday's Chinese Grand Prix, where the circuit has the longest straight on the Formula 1 calendar. Technical chief Adrian Newey admits the Milton Keynes-based team is finding it hard to come to grips with the device. Interlagos, the Sao Paulo track that stages the F1 Brazilian GP, is to make changes following the death of a driver in a truck race earlier this month. A section of stand will be removed to enable the addition of a slow-down area on the outside of the high-speed corner leading to the main straight. The Yas Marina circuit in Abu Dhabi is also making changes after being severely criticised for a lack of overtaking opportunities. Chief executive Richard Cregan confirmed alterations between turns 6 and 9 will be completed before November's penultimate round of the 2011 F1 championship.Paul di Resta claims he was hit several times by tyre "marbles" during the Malaysian GP. "In the middle of a fast corner, these lumps of rubber would be smacking into my hands as I turned the wheel," said the Force India driver. Tyre manufacturer Pirelli have responded by pointing out they were specifically instructed to provide tyres that degrade more quickly.Nick Heidfeld's third-place finish in Malaysia means the German driver now holds the record for the most podium finishes without a win. Heidfeld has finished second or third 13 times, one more than previous record-holder Stefan Johansson. Ferrari is planning immediate action after their cars finished fifth and sixth in Malaysia. "We need to introduce some developments as soon as we can, maybe from the next race in China," team principal Stefano Domenicali is quoted as saying.
