They can be hard on the weak link parts. If you're not looking for the extra tenth or losing by 100ths then stick with the foot.
Most in the victory circle use a brake.
Most of the time it isn’t going to be even close to a tenth. If anything.
There are a number of guys who footbrake that race in the big dollar events and win.
Nasty Nick Hastings being one of them, Kevin Pollard another. His little truck runs 5.30’s in the 1/8 off the foot. He unfortunately got it smashed by someone hitting him in the pits that wasn’t looking. Driving something else right now. There are others.
