I currently own a K swap Ej with;
KYB AGX's shocks (on some Megan 450lbs Front, 350lbs Rear spring rates coilovers)
Front and Rear full GSR suspenssion (brakes, sway bars)
drilled rotors and ceramic pads.

i'm seeking to get a quite stiff spring that will work great with the shocks i have now. I do not want to replace my shocks, i'm on a budget and the shocks are good.
i'm trying to set up the car for some road racing, auto X and over all great handling.


Whats are the best options on brands and springs rates available friendly with KYB AGX's?

thanks.

 

Hmmm....well you have all your typical H&R, Eibach, Tein etc... They're definately friendly w/your AGX's but I can't help but wonder whether those rates are too soft for auto x and/or road racing a k-series in an EJ.

I did a search for after market spring rates and found the following...don't know if this is much help but hopefully it'll start you out:

You're not going to be able to go a whole lot stiffer with the AGXs. I believe the max you'd want to go on them is somewhere around 550lbs/in. However, the biggest upgrade while staying on the AGXs will be changing your rear spring rates. Going to say a 500 front/500 rear rates will balance the car out more and give you some oversteer.

As for springs, you can buy Eibach coilover springs directly from Ground-Control, they sell hundreds with different lengths, diameters and rates. I've heard good things about Swift springs aswell. Personally, I'd recommend the Eibach springs...

 

I doubt the AGX's could take even a 400 lb/in spring for very long before going kaput.

 

Thanks man. It wont specially be a road race or auto x car to be honest, but i will enter a few events
during the year. I just want it to handle somewhat better since i drive the car often on the street.
I've tried but cant really find much information

Thanks man. I've heard good things about Swift springs too, but cant find info about them.
I just want the stiffest ride without changing my shocks now, eventually i will upgrade by the end of the year probably. K swap cars suffer fro
Oil pan ground clearance therefore a stiffer spring will help protect a little more. (got about 5-6 inches clerance)
