Will the 2020 technical rules really shake up Supercars?

Teams will face some critical technical challenges when the 2020 Supercars season formally kicks off in Adelaide tomorrow.

The headline act is a brand new aero package deal, sporting someplace in the area of 10 per cent much less downforce, to counteract a 2019 plagued with parity complaints.

Added to that could be a model new management damper package deal, a extra sustainable (and barely much less highly effective) engine spec, and the loss of life of the much-maligned tyre financial institution.

So which of the modifications can have the largest impression? And can any of it assist the chasing pack run down the large two, DJR Team Penske and Triple Eight Race Engineering?

Fox Sport’s formidable line-up of TV specialists, Mark Larkham, Craig Lowndes and Mark Skaife gave us their ideas.


I’m really enthusiastic about the technical modifications which have occurred.

For the first time in our historical past, the reality that each workforce up and down pitlane can have an aero map for his or her automotive is fairly cool.

Numerous the nous and good work we noticed from Ludo [Lacroix] and Scotty [McLaughlin] final 12 months, we identified on the telecast you may match Skaifey’s pockets in the hole between the entrance guard and the tyre one week, and the subsequent week it was the rear.

They have been really working the aero on these automobiles. The reality that everybody understands that now could be good.

The 10 per cent aero drop, I’m unsure how a lot that is going to do. But the really excellent news is that we’re on the proper path there, we have began that journey and that is a optimistic factor.

I’m really enthusiastic about the distinction the management shock may need on the class. It’s not going to present you all of the solutions. It’s nonetheless tuneable to a level. But the capability to place bizarre curves and do all kinds of digressive stuff and peculiar and wacky rebound curves…

If you consider the impression of a shock absorber, mixed with a twin spring – from the second you go for the brake pedal, to turn-in, and getting off the nook – with all of the totally different variables to tune it for various locations in the nook for top and low velocity, that is all gone. That degree of tuneablity is gone.


Suddenly you consider Chaz Mostert in a WAU automotive, and the Tickford guys, and Charlie Schwerkolt’s guys… this would possibly simply assist them bridge that hole.

The good guys are in the window, and so they’ll keep there. But it is the ones that have been falling out of the window that will not be capable of fall out of the window anymore. You’re nonetheless going to cock up, in fact you’ll, however it’s way more linear than it is ever been.

I’ve been in the shock division at each workforce in the nation, and I’ll let you know there’s some good ones. The disparity between them is large. So the shut that hole I feel is an efficient factor.

Even from a psychological viewpoint, a number of it’s notion. If you are attempting to do an elite sporting efficiency – does not matter what sport, or for those who’re an engineer or a driver or no matter – if the notion is that you have not received what these guys up there have gotten…

This will energise everybody. ‘I’m now in the sport, I can do that. I can run round behind Jamie, and what he is received, I’ve received too.’

That’s a fairly cool factor for a race driver to know.


Now I’ve seen the automobiles and pushed the automobiles, they transfer round much more. There’s little doubt the aero discount has given groups extra to consider. I do know Shane [van Gisbergen] labored quite a bit on that in the check, simply to know the aero platform.

The shock absorber facet of it, I’ve received to say the transition from the early morning [at the test], after we ran on the Sachs shock, to the Supashock… I used to be shocked with the feedback from Shane and Jamie, who did the back-to-back. They really did not really feel an enormous distinction.


But once more, they’ve had the alternative to dyno between the management shock and what we had earlier than. The adjustability with the Supashock nonetheless lets you get again to an analogous platform. So the drivers commented that there was a distinction, however not as nice a distinction as anticipated. And that is a great factor.

For me the platform coming into this season is extra balanced than what we noticed final 12 months. I feel the folks in Supercars concerned in the technical facet have finished a unbelievable job with the aero facet of issues.

It’s exhausting to go off testing instances, however Chaz Mostert was up there at instances, Scotty Pye was up there, so I feel it is balanced it out between the heavyweights and the different finish of pitlane.


It does create a extra degree taking part in subject. And any time we do this, it makes for higher racing.

There will likely be instances when a few of these smaller groups finish up midway there. You discuss the window, there will likely be instances when you do not transfer it very a lot and you will be going ‘gee my automotive’s alright!’.

There will likely be a number of work on anti-roll bar know-how, and there will likely be a number of work on geometry to go together with what we simply spoke about. Like all the time the good groups will likely be extra throughout it, however it can positively degree the taking part in subject.

Thirty to 40 kilograms of downforce continues to be a good chunk as nicely. I used to be really important of the aero degree we had final 12 months, I feel that it damage the racing high quality, it damage the tyre degradation, it damage the capability the go.

I feel the tyre financial institution is the huge one this 12 months. It makes whole sense to go from some groups having 250 tyres and coming again to 40.

You’ll get a kind information every weekend. For our followers, that kind information on a Friday afternoon is so highly effective. You must have the headline act on a Saturday morning for the newspaper to say who was quickest. It’s an enormous a part of the leisure package deal.

I like the engine modifications which have been made. I feel that can drag the price again a bit. That ought to have been finished after we did Car of the Future and we have been engaged on that without end.

There are a number of smaller modifications that bode really nicely.
