Recommended Spring Rates??

[matthewAPM]

The key words are bolded. The above set up ould be pure ****e for a street driven car, especially in Atlanta. The results would be too stiff.

I would recommend two things. First, of you're going to go with Konis, call Koni and tell them what you're doing with the car. They can recommend spring rates and struts that are going to be the best for what/where/how you want to drive. Second, if you're going to get GCs, call Ground Control and tell them the same things that you teold Koni. The two opinions should be fairly close.

no one said u had to run the same spring rates. running 400f/500r is fine. I daily drove the miata with 700 in the front and it was not that bad.

It wasn't the spring rates that drew my original statement. Replacing all the rubber bushings with poly will do more to compromise daily ride quality than the spring rates.

I drove a friend's Miata with essentially a Spec Miata suspension this summer and it wasn't really too stiff, but I think all the bushings in his suspension are still rubber.

But, for a dedicated track/autocross car, your suspension suggestion is spot on.
