Senna out to 'find the limit' in Korea, but reckons track will not suit Renault

According to the Brazilian, the team must avoid wasting too much time making big set-up changes during Friday running if it is to maximise its potential.

This means that the baseline set-up that Renault starts tomorrow morning's free practice session needs to be immediately in the right ballpark.

"We have been very seriously discussing the need to get everything ready as soon as possible on Friday in terms of having a car that behaves properly," said Senna. "We need to chip away and find the limit in stead of making massive changes.

"Finding the right set-up window is very important. We have been outside of the window a few times so more effort needs to put into this.

"This will help us to achieve much better performance from the car during the weekend. We are aiming for this and the way that we are starting this weekend is potentially much better than the way we started last weekend."

Senna added that the Yeongam circuit is not ideally suited to the Renault, which features an innovative forward-exit exhaust that has proved ineffective in slow corners.

The track has a blend of fast turns and slow corners, with the latter dominating in the final sector, meaning that Renault could face a challenging weekend.

"This place is not ideal for our car," said Senna. "There are a few corners that put us in a similar situation to Singapore and that doesn't help us.

"But we understand our problems and our trying to fight against them. It's going to be a very tight battle."
