David Reynolds praising the aero changes.<\/a><\/p>\nThe category\u2019s motorsport boss Tim Edwards has flagged the potential for even more tweaks, this time in the name of tightening the \u2018balance parity box\u2019, rather than helping the Camaro.<\/p>\n
\u201cWe have two parity boxes,\u201d Edwards explained to Speedcafe.<\/p>\n
\u201cWe\u2019ve got the primary one, which is the downforce and drag parity box, and then we also have a balance parity box, and you\u2019ve got to be inside both boxes.<\/p>\n
\u201cThe balance box is a larger box than the downforce and drag one, in simple terms.<\/p>\n
\u201cWhat you\u2019ve seen over the last two rounds is the Camaro\u2019s moved from being in sort of the top left corner of the [balance] box to being in the bottom right hand corner of the box.<\/p>\n
\u201cWe\u2019ve looked at it and gone, \u2018well, is this box too big?\u2019 Because you\u2019re still inside the downforce and drag box, but now we\u2019re all dancing around in the [balance] parity box.<\/p>\n
\u201cIf we could just nudge it slightly in one direction, we think we could then reduce the parity box by a significant amount.<\/p>\n
\u201cBut these things take time. You could say, why didn\u2019t you just do that change now? Well, we\u2019re still trialling all different things and looking at wind tunnel versus CFD correlations.<\/p>\n
\u201cYou\u2019re talking about another very, very small change. But if we can reduce it, that\u2019s great, because it locks them all in a much smaller space.\u201d<\/p>\n
The combination of the off-season wind tunnel testing, CFD modelling and track data means Supercars has more information than ever to work with.<\/p>\n
Asked directly if another change is on the cards for Darwin, Edwards said: \u201cMaybe. We\u2019re exploring it. If we can\u2019t find the right tool, then we wouldn\u2019t make a change.\u201d<\/p>\n
The desire to reduce the size of the \u2018balance parity box\u2019 is the latest example of Supercars\u2019 determination to make the three different body shapes perform as equally as possible.<\/p>\n
Its wind tunnel-enhanced efforts to achieve overall downforce and drag parity in recent years have put the spotlight on any difference in aero balance between the cars.<\/p>\n
Ford successfully lobbied for a change midway through 2025 that shifted its aerodynamic balance rearward \u2013 a move that appeared to turn around its on-track fortunes.<\/p>\n
Edwards stressed the magnitude of the changes in aerodynamic balance being talked about are incredibly small.<\/p>\n
\u201cIt\u2019s like when you check in at the airport and you\u2019re one kilo over and you open your bag up at the counter and take a pair of jeans out and put it in your backpack,\u201d he said.<\/p>\n
\u201cWe\u2019re taking the pair of jeans off the front bumper and putting it on the rear bumper. It\u2019s such a minute changes we\u2019re making,<\/p>\n
\u201cBut that\u2019s how close we are now, that these minuscule changes. We\u2019re all dancing around the point of the needle.\u201d<\/p>\n
