Brakes won’t ‘hold’

I’m certainly not trying to ‘abuse my baby’ as she is most certainly that. Especially not when I only take her to the track a few times a year.

I have actually thought about a line-loc (bc I will be swapping a 5 speed in the not too distant future) but I was concerned that wouldn’t work either if there was a brake issue.

Also I was torn because it will always be at least %95 percent street driven so I didn’t want to see a big red button and wiring in an otherwise pretty stock interior. I may need to get over that though
I set my line lock up with a 3 way switch using the output side of the horn relay.
switch up, horn. switch down, line lock.
pull thru bleach box, set brakes hard, hold horn button. release brakes, apply gas, release horn button when you see smoke. easy and "invisible"!!
