Have the TEIN STechs now and as I do not daily drive my car and im starting to get more into AutoX im looking for stiffer springs. I don't want the hassle or price of coils so this is why im sticking with springs.

Best I found so far is 690LB front and rear.

Anything else out there? I also want something that's going to drop the car some too. The STechs look good, I don't want the car to be jacked up.

 

The springs above will give you a 1" drop all around.

 

That's a little less than the S Techs. Why cant someone make a spring that's stiff enough for competition yet drops the car to look good. I hate compromising.

 

Those should be stiff enough.
I bought the same ones to use with TC Kline DA shocks. I haven't installed them yet but they are suppose to be stiff enough for road course duty.

 

$420 for springs. thats just crazy...

 

With such high spring rates, you're gonna need to step up to shocks capable of handling the rates(if you don't already have them), defeating the original intent in saving money.

IMO, if you want such high spring rates, it's probably much easier to just go with coilovers.

 

Do not even remotely consider those springs for anything other then the Tc Kline or Koni Race shocks (not Koni sports).

Not a rear spring rate choice I'd make for autocross where you have to get out of the hole in lower gears frequently, especially if you don't have a aftermarket LSD. Some say the ability to rotate the car is the key, just make sure you have enough traction to get out of the hole when you need to.

Are their stiffer spring choices that have a mild less then 1" drop then S-techs? No. Well at least not inside the box. Thing is, you can only go so high with spirng rates and still have a shock that will deliver on the course.

How much spring rate do you want to try and what drop range would be ideal for you?

 

I would spend more money upgrading the shocks first and then the springs. Springs that have that high of a rate on oem dampers are going to ride very bouncy.

 

Was going to go with the Tokico D-Spec shocks, but your right 400 for springs another 550 for shocks plus shipping is not much less if any less than a set of coilovers.

So... I am looking into the BC Racing coilovers, 10k front and 8k rear. How do those rates compare to these springs? Why can't they all just put the spring rates in lbs damnit?

 

Tokico D-specs cannot be used with spring rates past 450lbs per Tokico's own techs. Even Koni sports should not be used. I have run the Konis as a coilover setup with 448/427 and 560/427 rates, they should not be run with rates higher then that.

Tc Kline shocks are valved specifically for the Nismo T2 springs. That setup vs any tuner coilover (off brand) setup will be very different in valving performance and offer you unique tuning in the form of independent rebound and compression dampning performance. You can purchase the Tc Kline shocks at a group buy rate of $1000.

 

Thanks for the info.

I think I have decided to go with Coilovers though. Higher spring rates, adjustable dampening and cheaper than going with the plan I was looking at.

Either Stance GR+ PRO with 14k 12k or the BC Racing with 10K 8K it all depends on pricing of the Stance since I already got a price for the BC Racing. Both seem like really nice Coilovers so we'll see.

 

You do understand that either choice is very different in terms of how much spring rate makes it to the wheel. IMO, you should consider how a product is valved, not just spring rates along. Most every coilover offered and installed since this board started in 2003 ends up receiving a glowing review by their owners, with perhaps the exception of Tein basics. They can't all deliver. IMO, their are other choices in your situation that should be looked at, Cusco Zero2, HKS III sport, Tein Monoflex, even Bilstein PSS9 revalved and resprung.

 

cobb tuning?

 

I want someone to verify their claim of 15% stiffer then oem on the springs. Would be nice for someone to take a dial caliper and measure their spring vs Hotchkis springs. Of course the reason for the doubt deals with who makes the springs for them (Hothckis) and how in R&D they didn't know pre 2005 car's had different shocks and different rear spring rates.

If someone were to offer to send me a single front and rear spring from both companies, I'd be happy to offer independent confirmation one way or another and ship them back on my dime within 48hrs of receipt.

 

This is really deep for me. Im not thats smart durrrr. I dunno, I know what you mean about making sure the shocks and valving can handle the high spring rate, but how do I do that. How do I know what's best for me? I don't race the car ever day, hell I rarely drive it, but I am all about how the car handles. The tighter the better, the faster i can take a corner and the quicker I can get out of it the better. It's not my DD and stiffnes does not bother me.
