No I'm not talking about street cars I'm talking about track only race cars. There is absolutely replacements for this that do not contain lead. Here is only one example.

But there are also certain events where people are absolutely bringing out 40-50 year old drag racers.
I don't believe that particular product you have linked to has been on the market for over a decade. I suspect the additives they used in place of lead were probably even worse. If you can find an unleaded racing fuel above 110 octane for sale today I will happily eat my words.
So at this point even for super high octane needs there is no requirement for running a leaded gasoline anymore and hasn't been for some time.
