I called a place called Springworks and got new rear springs for my 95 accord, I told them i had alot of weight in the trunk and would be adding even more, took them about 4 weeks to make them though.
I got them and put them on and with 4 d3100s, 2 40 lb amps, 3 sundown nightshades and a heavy ass box im still above factory ride height.
only problem i has is there rod they used to make the springs was such a larger diameter the spring looks like it wont fully seat down on the strut bracket, so a shop i had it at refused to do it, but then i decided to do it myself (actually a pretty easy thing to do), and they went in great, if you go this route you will need a spring compressor though. they are cheap though, only 35 buck at autozone.
also, the spring ends did not match the stock spring ends, so the compression makes in the rubber on the strut were off. and that is the way how-to videos tell you to line them up. the way i did it was to just leave the top of the strut still bolted to the car so i didnt have to bother lining up those bolts later.
I also have my stock springs i could measure, but i doubt they are the same measurements.
dang that was long..
edit, i just noticed your from cali, thats where springworks is too, maybe they are close enough to you to stop by. I think theyre in Santa Rosa
