Ferrari is pressing ahead with a front wing design that violently "fluttered" when attached to Felipe Massa's car recently in India.
In parc ferme, viewed alongside the dominant Red Bull design, the 2012-style Ferrari wing is nearly identical to the ones raced by Sebastian Vettel and Mark Webber and reportedly designed to 'flex' at high speed.
But in India, one version fitted to Massa's car behaved oddly, with technical director Pat Fry pointing to a "quality issue".
"Much work has been done to modify certain aspects of it before both drivers will try it this coming weekend," the Briton added ahead of the penultimate race of the season in Abu Dhabi.
Fry said the development is worth persevering with.
"It does change the characteristics of the car and getting to understand how to get the most out of it is certainly an interesting challenge," he explained, "and in the short term it has helped our performance."
