i'm re-doing the brake lines on my race car now i wanted to do a brake line tuck and i have a few questions what style flare do i use when goin from the hardline into the bulkhead wich is -3 or does the tube nut sleeve make its own flare when i tighten it up??? also is there any down fall to using a stock LS prop valve with an inline staging brake?? or should i just go with an adjustable 1 for the rears and no prop valve for the fronts
