You were told wrong. If you are trying to maximize performance, you can only determine the best spring at the track. The springs that generate the lowest et, best mph, may, or may not be smooth on the street. Weight, gear, and converter play a key role in what springs are best, and whether or not there will be a sag when they come-in on the street.

what BSB67 says is fact. as far as the short yellows slowing a car down; the short yellows actually have a slower opening rate than the long yellows. this is per holley's info. i don't know why they even marketed them. i use purples for street use but yellows go quicker. from a standing start you won't feel any soggy spots, like from a kickdown, with softer springs. anything heavier than purples is worthless.
