Streetable pads/fluid aren't designed for hard track use. Unless you have a C6 ZR1 with the carbon ceramic brakes, you need to upgrade the pads and fluid for track use... if you're an advanced driver. For the novice the stock stuff will be fine to get your feet wet. Been racing/instructing with NASA for a decade.

beside ive boiled my fair share of brake fluid....i even boiled it driving on the street and its takes more than just one or two seconds for the fuild to cool off,,,,,more like afew corners to half a lap to get the pedal back......this guy claims to get the pedal back after only afew seconds

When you boil fluid in the calipers, it transforms to a gaseous state, which means that it compresses more easily than when a fluid. Typically, pumping the brakes several times will get some degree of pedal return (assuming you have time to do that). It doesn't have to be "a few corners" (which defies logic since you're on the brakes in the braking zones approaching those corners) or a "half a lap".

speaking of defying logic isnt it logical that after experiencing a soft or floored brake pedal a logical person would then slow right down, cruise the next few corners to half a lap frequently checking for return of the brake pedal and not try to continue at the same pace that boiled the fluid in the first place as you insinuate?????
But yes, if the pedal goes soft or "floored", that would be an instant clue to get out of it and pit in. However, since fluid often boils when there is no pressure in the system (between corners...and because pressure raises the boiling point of liquids), it can boil in the calipers between corners.

Typically, lots of drivers won't have that chance.

I'll take that bet at Sebring. I'll even keep my own C7 in Florida for a few more months. There is a single day event with Chin in July. We'll find an escrow to hold $5k each on a $20k bet. You can datalog the car however you'd like and I'll have XP Motorsports monitor it as well. The car will be 100% stock with factory fluid and pads in it.
What now?

op made it clear the pedal was floored and zero brakes, not a soft pedal with some .......thats means it was extreme fluid overheating.....but yet the pedal came right back in seconds .....therefore no way the fluid was boiled in the first place let alone in 1.5 laps in a c7 at that modest pace
