I bracket raced for years. won many events 1992 pro street champion at gainesville. won 2000.00 at wdiz street machine nats. in 93. with a mustang ll no tach stock shifter ran hi 13s. some tips I can offer for consistancy, run slicks definately. make many time trials. and dial your quickest time dont try to sandbag. if your are ahead by enough let off. dont screw with the tune between rounds. shallow stage every time,when the second staging light lights stop dont roll at all this will make et more consistant.maybe a little slower but consistancy is what you are looking for.I am building another mustang to race now . it is a lot of fun to run if you win sometimes.
