Default Best Springs with Koni Inserts

Im trying to figure out the best springs to use with Koni inserts on my 02 WRX wagon. I want the best setup for STX autox while stopping short of getting coilovers. I've been comparing Prodrive to H&R. The Prodrive springs seem to be well engineered but were apparently designed for the stock struts so are probably softer than the Konis can ultimately handle. I've heard people bitch about the H&R springs being "bouncy" with the stock struts which suggests they are stiffer (and maybe better for autox??) than the Prodrives. I've read that the Konis solve the "bouncy" problems. Are there any other springs out there that are on the stiff side that I should be considering? Anybody got a list of spring rates?

Anyone got any input?

Also, what is best for this application - linear or progressive rate springs.

I'll be upgrading sway bars, end links, camber plates, wheels tires etc too.

SPT kit springs. Improved handling without lowering your car. Just something else to think about.

I'd personally get a linear spring rate for race use. From there, I would decide on the spring rate you want to use. There ultimately is no best until you find what works best for your setup and driving style.

Happy reading!
Yep, the Prodrives do very well with the Konis. It's hard to go wrong with this setup unless you really really really like stiff suspension. Set on full stiff the ride on the street is tolerable at best.

Enjoy,

Scott

Hmmm, "tolerable at best" sounds pretty stiff. Damn, I wish I was about 2000 miles closer so's you could take me for a ride and bruise my kidneys up a little (I guess that last statement could be misinterpreted )

I haven't heard one bad thing about the prodrives - might be the way to go - I guess if they don't beat me up enough I could sell them and get some GCs.

I gotta give a big vote for the Prodrives as well. Unbelievably good around them cones. I didnt even go full stiff, and i beat the whole field at the last AutoX , course i live in the sticks.

I am loving the Koni/Prodrive combo, i personally wouldnt want a stiffer spring for my car and my driving. Like Sdecker said, tolerable on full stiff, on the streets.

Big thumbs up and a big salute to Sdecker for doing the write up that sent me over the edge to get the Konis.

I just re-read your original post talking about spring rates. Koni says that the yellow SA inserts are good for spring rates up to 400 lbs. Although Prodrive won't officially release the specs on their springs, the best guess is 215F/195R, right around 10 percent stiffer than stock. They match up very well with the Konis. I chose not to go the Ground Control route for the same reasons I didn't go with coilovers -- just too much futzing around all the time. I don't have a set of scales to corner weight the car, and that has been known to make a car handle worse than before the coilovers.

Good luck to you...let us know if you have q's about anything.
