Tekno Autosports will stick with its current suspension package when it rolls out its latest chassis for Shane van Gisbergen this week.
The fresh Darrel Lea STIX car will be shaken down at Queensland Raceway on Wednesday sporting the team’s existing ‘Mk 4′ Triple Eight front suspension.
Triple Eight’s factory entries have been running an upgraded ‘Mk 5′ version since mid-2013.
The front suspension is the biggest area of design freedom under the Car of the Future rules, which saw the category move to a control chassis and rear suspension from 2013.
Tekno had been set to upgrade its car’s front-end ahead of this season, before deciding that the funds required could be better spent in other areas.
The two versions have subtle geometric differences that are thought to contribute to the contrasting fortunes of the Triple Eight and Tekno entries at different circuits.
While there remain doubts over the benefits of the upgrade, Tekno driver Shane van Gisbergen believes that continuing with the previous generation suspension comes with its challenges.
“I’ve never driven the Mk 5, so I don’t know if there’s any real performance gain,” said Van Gisbergen.
“(But) there is some set-up stuff that doesn’t work (translate) between them, which makes it tough for us.
“When we struggle we can’t just bolt their (Triple Eight’s) set-up on because the car is different, so it’s hard in some ways because we’ve got to go our own way.
“We really are a single car team whereas if we had all the stuff we could just bolt their stuff on and be away. But it really just is what it is.”
“The Tekno guys are a great team with a good driver, engineer and team manager, so they should be right up there (regardless of which specification they’re running).” Said Red Bull team manager Mark Dutton.
Tekno’s fresh car is meanwhile expected to feature Triple Eight’s new-for-2015 method of brake bias adjustment. The adjustment lever, rather than the usual knob, in order to enable their drivers to easily change the bias between corners.
The traditional, less user friendly method sees brake bias changes made only every few laps in order to compensate for the lightening of the fuel load during a stint.
