The swap by Triple Eight Race Engineering from the traditional V8 Supercars brake bias adjuster knob to a lever has rivals pondering its potential advantages and whether they will follow suit.

T8 has been running the lever in the Red Bull Holden Commodore VFs of Jamie Whincup and Craig Lowndes since the start of the season, but the change only became widely apparent to rival teams via in-car vision during the Tyrepower Tasmania SuperSprint at Symmons Plains in March.

The brake bias adjuster is one of the tools a driver has to control the handling of his car during a race. For instance, the bias would be wound further to the front as the fuel load lightened to prevent lock-ups.

The knob traditionally used in V8 Supercars is a 'set and forget' item which might be adjusted every few laps.

However, the belief among rival teams is that the T8 lever would permit constant adjustment during a lap, potentially allowing the brake balance to be changed between consecutive corners.

The lever sits to driver's left, whereas the knob is normally placed down to driver's right. The new set-up was designed by former T8 senior engineer Jeromy 'JJ' Moore, who left the team over the summer to join the Porsche World Endurance Championship program.

Red Bull Racing Australia team manager Mark Dutton admitted the lever did allow quicker changes.

"It is quicker, it is easier to access, and it is in a more natural position. They are the main reasons for it," Dutton told v8supercars.com.au.

"This (lever) is just easier. You could do that (adjust brake bias between corners) with the old one. There are no extra capabilities that you couldn't do with the knob that you can with the lever.

"But if you can do it more easily and repeatedly then you might open up the scope to change it more often around the track."

The move to a brake bias lever might sound like small beer, but in a Championship where much of the technology is controlled, any performance gain is vital.

Dutton emphasised the ergonomic advantage the lever provided the driver, something which potentially also translated into improved performance.

"You don't want the driver to not be able to do what he wants to do because it's not in the right spot or not quite easy enough to do, whether the steering is in the right position, the brakes are in the right position, the right angle of the seat.

"There are a multitude of things that people don't give enough credit to and that's just another one of them ... so ergonomics is a huge deal and it might sound boring but that is a performance thing."

Walkinshaw Racing's technical director Mat Nilsson said the lever had been spotted and confirmed there would be an investigation to establish whether the feature developed by WR's Holden factory rival was worth pursuing.

"We have discussed or flagged that Triple Eight have a system," he said. "So at some point we will probably look at it. But you have to pick your priorities and go from there.

"If it is a quick and easy change they can do then you do get an advantage out of it because they can change it more quickly and more regularly than what we can with a traditional bias adjuster. So they are probably in a situation where they can change the setting multiple times a lap."

Prodrive Racing Australia team principal Tim Edwards said the factory Ford squad was also pondering the lever and what - if any - response it might make.

"We have noticed it, it just depends what you are trying to achieve. For a particular corner on the track they might need a certain bias and on another part of the track they might need something different. So it's just a quick way of tuning the balance on the same lap.

"It's like anything, you see another team doing it and you have to evaluate whether you think there is an advantage in it and whether you want to do it or not.

"But I'd like to think there are things that are not so obvious we are doing that they are not doing."
