RS-R springs???????

Anyone know if they're any good? I've read they have a progressive spring rate so they're supposedly better than some but I don't know anyone that's got some on their car. Any thoughts?

i did'nt even know rs-r still existed...
back in the day (97-98) rs-r had some good quality shit..
don't know if it helps ,but after 3 days you finally have a response!!

Thanks for the response. I found a guy that's got some for cheap but no one seems to know if they ever ride any good. I know the drop on these is 1.5" but I have no idea if the progressive spring rate lives up to it's name.
