Renault technical director James Allison says the team has yet to decide whether or not it will continue to run its F-duct in the Italian Grand Prix this weekend.

Renault introduced the part to great success at Spa as Robert Kubica secured a podium finish and Vitaly Petrov came through the field to finish inside the points.

While the ability to stall the rear-wing paid dividends at Spa, it remains to be seen if it the part will be of use at Monza thanks to the low-downforce nature of the circuit, with Allison saying the team hadn't decided if it will run the part in the Italian GP.

"Monza is very different from all the other circuits and so we have had to prepare a bespoke package that we will not use anywhere else," he said. "Monza has such long straights and so few corners that it requires much smaller wings than any other track. To add further complication, the f-duct is a potential alternative option for Monza. Like several other teams, we too are evaluating whether we can make the device work in the particular, low-downforce environment of Monza.

Allison added that he was hopeful of a strong weekend for the team again at Monza - regardless of whether it runs the F-duct or not - as the team seeks to close the gap to Mercedes in the championship standings.

"Monza is very different from the mainstream bunch of tracks that make up the calendar, but generally speaking the cars that are good at one track tend to be good everywhere, regardless of the downforce levels," he said. "The performance of the R30 in Spa therefore gives me confidence that we can compete for similarly good results at all the remaining tracks, including Monza. We will be aiming to get both cars well inside the top ten both in qualifying and the race this weekend.

"We're currently 23 points behind Mercedes so we've got to take four points off them in each of the remaining races. We only managed to take three points out of their lead in Spa, but I'm hopeful that, if we can maintain our current level of competitiveness, we can start finishing ahead of Mercedes with both our cars. If we can achieve that, and race effectively with no reliability issues, we stand a good chance of catching them by the end of the year."
