Thx,
Did they also suggest you change the oil as well ?

This clearly falls under " overkill".



Most HPDE organizations recommend you have fluid that is less than six months old when attending an event.


If you want your car to be in the absolute best possible shape .. you can Change all fluids - oil, trans , diff and brake fluid after or immediately prior to every track event... or both !


But seriously , it's much easier to simply replace the stock brake fluid with a high temp brake fluid like Castrol Srf. It's around $60-80 a liter but has an incredibly high wet boiling point that is better than the dry boiling point for more than 90 percent of the products on the market.
