Spring rate recommendations for coil overs and Koni shock ?'s on an FC.
1987 RX-7:
I am going for a 70% street car and 30% track car. Still yet to purchase coilovers and shocks..... but I'm leaning towards K2RD.com coilover kit and caster/camber plate setup and then buy Koni's from Ground Control.
What spring rates are you guys running up front/rear?
I hear 400lb up front and 275lb rear is the norm. I want the car to handle like a ****.
What Koni shocks would you guys recommend with the coil over kit?
Is a strut tower brace worth the cost and how much stiffer does the car feel?

The k2rd kit comes with 350Front and 225 rear, I believe. I'm very happy with the kit, Paul at k2rd is great to talk to on the phone and his products are nicely made. The camber plate is a much better and the GC unit, IMO... k2rd's kit puts all the shock bound load on metal plates in compression. The GC kit puts the bound load on four bolts (in tension!) tsk tsk, ground control.

Ted,
With those spring rates how do you feel the car is as far as stiffness? If you were to do it over again would you get less aggressive front springs?
I imagine my car will weigh 2730-2750lbs in street trim with spare tire etc.
What is the corner weighting of a stock FC?

I am looking at getting either 400/375 fronts and 275/250 rear.... I spoke with Jay at Ground Control and he said they rarely go over 400lb springs in the front even on V8 Z car conversions.
Someone has had to have corner weighed their FC before.

the k2rd camber plates won't fit on konis. different shock sizes. if you want a koni/ coil over kit check out the ITS kit at www.mazdamotorsports.com
I have the k2rd kit with 350/225 and it seems good for street. I don't think I'd want to use the agx's on the track though. I hear they don't hold up.

Don't hold up? I heard of a guy on here who was testing prototype camber plates for k2rd and whacked a curb so hard that he BENT the camber plate, but didn't blow the shock. Besides, even if you did blow the shock, you can buy 3 agx's for the price of on koni... well, two anyway
