Hi i have an older set of qa1 single adjustable coilovers for the front, the springs are a dark gray color and say qa1315 OER or something like that on them, does that mean they are 315# springs? I'm basically only drag racing the car now with very minimal street driving, i want to get the most out of my track times and hook on the street without having the front be too soft. i was looking at getting the 275 springs, would they be too light if i dont have a tubular k member and control arms? The only weight reduction i have now is the sway bar removed, a/c system, racestar wheels and will be doing a abs delete soon

 

That should be a 315 pound spring. I would recommend sticking with that for a bit and when you have more lightening done, consider dropping the spring rate lower.
