From what I have read, and been told, the standard height may give around 1/4" of lift until they break in. It's common to have the illusion of an inch of lift, but it's actually because you are used to the worn out/tired original springs that were on your car. But again, that's just what I have read, and been told. I plan on towing a snowmobile trailer from time to time, and don't want the rear end to sag to much, so if I have good struts, with at least rear King springs, I should be good.
I measured the top of the wheel arches before and after, and I am running larger tires with no rub ever and no bashing/trimming (205/60R15 or 185/75R14 depending on the season). I also put on new GR2s with the springs, so maybe that added some as well. The lift is not an illusion.
Regardless, the springs are great, and paul at primitve racing is a very nice guy to deal with. He can also confirm the lift that the springs produce if you dont beleive me.
