H&R Sprint Rate
Anyone know off hand what the Sprint rate for H&R Springs are for the FD?
I currently have them on KONI shocks and am unhappy with the harshness of my ride.
I know the stock rate is 280 front and 200 rear.
I'm trying to find the rates on Eibach springs from their website, but all it says is that the springs are a progressive spring and can't have any definite spring rate.
BAH!

Eibach only make Pro-kits for the FD and those are linear springs. Anyways, I had the Koni Yellow + Eibach Pro-kit combo on my FD. The ride was so harsh all because of the Konis, even on full soft all around.
I took off the Konis and put the stock shocks back on a the ride was so much quieter and smoother. The springs make very little difference in ride harshness.

the stock spring rate is 206lb-in on the fd front and back
on h&r springs fo rthe fd is about 150-300 i believe.
i do not prefer progressive type springs.. get some coilovers if ud like or if u think teh ride is too harsh get your stock springs and keep the koni shocks..thats a winning result

Well, I have a friend with Eibach springs and Koni yellow and his ride is quite soft and isn't too low.
My car is too harsh and too low (on the highest perch too), so most likely I will go with his setup because i know it works. He is also on 18's like me.
Either that or sell it all and get TEIN coil overs.
How much could I sell complete H&R springs and koni yellow's for?

Stock FD spring rates are about 280/200 lbs/in. Although it isn't all that clear, the answer is available here:
http://www.scuderiaciriani.com/rx7/suspension.html#SPR
I've read 280/200 and Bernd (who knows what he's doing and has the right equipment) verified those values by measuring the stock springs. All cars from the same year had the same springs, and they were softened very slightly in 94. I think the WHEEL rate (which is a factor of both spring rate and suspension geometry) is 106 lbs/in front and rear.
I've been on a soft spring tirade for a while, and I think I learned a bit by changing the rates on my car (which turned out to be somewhat different from my expectations). 550/450 made it scary to drive hard because the rear end didn't stick. 550/250 was fun because I could drive the car hard again but it understeered pretty badly. 450/250 gives me more wheel travel than I'd like in the front but balanced things out nicely (as far as I can tell on the street), so now I am thinking that 550/300 or 550/350 might be the ideal setup for me. If I didn't have the 550s laying around, I might start with 600/350 or something.
The only on-topic point I'd like to make is that coil-overs are nice because you can change ride height and spring rates easily. They are worth strong consideration if you are going to use the car for any sort of sporting activities, or just want to be able to adjust things for cosmetic and rubbing reasons (a major plus when you are pushing the limits with your wheel and tire sizes).
