Over the last, say 25 years, companies have supposedly been making huge improvements in chassis and suspensions to improve handling/grip
We know tires can have a big impact on grip and road feel too though. And tires have also been improving with time.
So my question is, which has contributed the most to cars getting better and better handling/grip over the last 25 years ago? Has it been because of suspension and chassis engineering and technology getting better or does it have more to do with the tires? If it’s the tires, do you think companies are possibly fooling us into thinking they’re making rapid progress and making much better cars? Or have the cars’ engineering and tech and tires both contributed equally?
