alright i have tokico blue shocks and tein s springs (i had thought i had heard they were the stiffest but from what i am reading now i believe i was incorrect) i dont mind a stiff suspension and i am also going to purchase all polyurethane suspension bushings for the car. my question is do you think it would be best just too go for he racing beat srings and sway bar set and resell the tein springs...

or stick with the teins and get a convertible front sway bar and t2 rear sway bar? ohh and this is going to be a autox/hillclimb/trackday/streetlegal car.
This is on a lightened s4. another option is custom race springs? and if you suggest those how would you sugest going about picking rates or what would you suggest?

ohh and for anybody that sugests eibachs they have been discontinued...

hmm also the tanabe springs could be a option with the convertible sway bar and t2 rear bar? so yea oppinions please

if you don't mind a stiff ride, go buy some coilovers. That'll send the bumps right to your body.

If you're going to switch sway bars, why not just get some good aftermarket ones that are stiffer?

also, you may want to try different roll bars one at a time to see how they affect the car's handling. with some stiffer aftermarket springs (not even coilovers) the stock antiroll bars can tend to make the car more oversteer-y, so my suggestion would be to try one suspension upgrade at a time to get the feel for what the car needs next. Save anti-roll bars for last, since they can be used to easily balance front vs rear grip in a turn while not seriously affecting ride otherwise

Not a bad idea at all....

I hear the tanabes are the stiffest.

They still suck though for performance driving.....I used to have them and because they lowered the car and still weren't that stiff, I got insane body roll. I then switched back to stock springs and felt so much better after that.

If you're going to lower your car, use at least coilover strength springs (i.e. buy a coilover kit)

Or get RS*R race springs, stiffer than the GF-210. They're about the stiffest you can go before coilovers.

I have them on my Ohlins shocks, and I get no roll whatsoever, even with the stock sway bars.

Register at Mazdaspeed Motorsports Devolopment so you can get good pricing on race parts. I recommend starting with the Stage II suspension kit (K-STG2-91-RX71).

Otherwise, you can order a nice coil-over setup from race shops that will help you choose the springs and dampers for your application.

Also, you can get coil-over kits for the Tokicos, but they are a little light for racing the 2Gen and spring rates would be more limited.

You can save a LOT of trouble if you install the bushings along with the new suspension components. Besides, new suspension components + old bushings = bent or broken formerly-new suspension components.

Yes, most of the Japanese bling springs suck for performance driving.

the eibachs have been discontinued, but you can still find them all over the place, altho i doubt that these are as stiff as you seem to want

Geez, all Eibachs, or just the pro-kit? I run ERS springs on my Rx7, and it's hard to believe they'd just fold up and go away.

I second the RS*R springs. I have them with my Tokico Blues and I love it. They are very stiff and there is very little body roll. Spring rates are 334f and 225r.

Yeah, the leading race spring manufacturer isn't going to just fold up and go away, lol. The ERS springs are still available by the ton. The Pro-Kit may have been discontinued, but it is still showing on the Eibach website and in the 2006 catalog, as well as on the Mazdatrix website.

Sweet, I didn't think so. My rates are 440lb fronts and 300lb rears. You want to talk about stiff! I had to put a harness in to keep my head from hitting the ceiling when hitting bumps in the road.

It's good to know they're still there though, because I really need to pick up some softer springs to keep around for street use and more comfortable driving. But around Dallas, the roads are pretty nice, so it doesn't beat you up too often.
