Tires can make your car a super hero too. That’s what I learned when I was getting may azz beat in autoX by fully stock cars. Rules allow any tire that is DOT legal. So everyone runs the hoosiers and kumhos, heat cycled and shaved. Once I bought my tires I dropped my time 6 seconds on a ~55 sec course and was staying up with M3s C5s and miatas.
For the record the tires are toyo Ra1 full thread depth road race tires( not shaved or heat cycled). I bought them cause they supposedly can last 10-15,000 miles of wear. Thus allowing me to only have one set of tires. They are not the best for autoXing or drag racing, but have been great all around.
Here are some low quality vids of that testing day(kinda boring though)
