I am trying to sort thru the massive amount of info on here about springs, and it has brought me to this question. We have L, KA, PA (P spring shows as discontinued). Consensus here seems to be that for a multi use Street/Autocross/4 day year track event car, P springs are a solid answer, however I'm having problems with getting them (current PA) in stock.
So here is the question - I can get the L springs, listed as "2007-2014 MUSTANG SHELBY GT500 SPRINGS". They state a 1.25" drop vice the 1" drop for the PA springs. What is the effective difference between the KA and PA spring, and for a majority street with 4 track days a year, should I wait for stock on the PA spring?
