Doesn't matter how many times a year you go, what matters is how do you want the car to behave/perform when you get there. 7-8k spring rates are generally too soft for the track if your running a good extreme summer tire. 10k is a better overall balance for track and street duty. But what also matters is the damping strength and consistency the damper provides, which if good, can help "mask" some of the character of a under sprung chassis with better control, but its not ideal when your bottoming out/on the bump stops in a turn because your G load generation is exceeding the springs ability to support the car. I cannot comment on how effective the damping is on either of those options in a track setting but they would be a compromise. Its a comfortable street coilover that gives you the option to lower your car, thats all that should be expected.

 

Junky is correct. The GTs are an amazing daily coilover and will perform ok on the track. You would need something with higher spring rates to get your times down.

Have you looked in the Hipermax SPs? Our customers are surprised at the ride quality considering the higher springs rates 16k/16k. There are people out there daily driving on these with no complaints.

So that may be something you will want to look into if you plan on tracking the car.

 

The Bilsteins would be a good street choice, but the springs would be too soft for any serious track work. If you are considering serious track days, thumb through the threads and posts by track day drivers on brakes, tires, etc. Different pads and cooling are a first step, many also find more substantial rotors, front and rear, are important. They can also give you insights on the shocks and spring rates. My preference would be the Eibach Multi-Pro-R2. I believe they are only available from Evasive who special orders them in batches from Eibach. There was a used for sale on the forum. At a lower price point, you would have the Fortune and HKS, with Ohlins in between.

There are lots of different technical details to shocks. Twin Tube (KW) or monotube (OEM and virtually every race car in the world). External reservoir or not; the rear shocks are short and OEM went to one, only an issue for monotubes. There are also a mass production design decision made on many monotubes below the Eibach's price level (not including the Bilstein). But that doesn't seem to be an issue in practice.

 

Dunno if ur still interested. But the tein flex z are about 6-7 hundred. And they are a noticeably better ride quality and and bounce than stock while staying stiff. Lowered about 1.25". Honestly cant say anything bad. But just put em in. Install is basically same as reinstalling stock. Tein is very well built and good value for the money. Just my opinion.

 

I doubt $600 Tein ride better than OEM.

Unless the OEM are BEYOND blown.

 

Maybe but ive driven in a friends S with oem also. The teins are def a tad on the better side than oem. But thats just the way it feels to me after multiple trials with dampness settings. Ive also used tein s techs. Koni yellows. Konis are good for really low cars imo, Also still testing out the tein flex one week in now.

 

"Konis are good for really low cars imo"

dude what.

And dampness settings? Come on man.

 

Just difference in opinion man. But maybe you know the more technical stuff of how they work or something maybe thats why ur opionion differs. But either way you seem more knowledgeble on the subject so ill take ur word for it.

 

To explain a bit...

Konis usually work pretty badly on super low cars. That's because they're not shortened....they're the same length as stock. The *fact* is that when they're set low, they don't have room to work well. The other fact is that they work much better at ride heights closer to stock.

People slam cars on Konis all the time, though...and...if they're happy, then I'm happy (I'm happy anyway because I am extremely good looking).

Glad you like your Flex Z. Tein makes decent stuff. Maybe the Flex Z for the S2000 works well. I've not tried it.

If corrosion isn't an issue, I'd pick the Bilstein all day over the Flex Z, however.

 

Bilstein PSS's are nearly twice the cost of Flex Z's though. They also won't go nearly as low as a set of Teins and maintain any sort of damper travel. The PSS line is more of a street biased coilover, while the Teins are more of a street/track setup with much higher spring rates and the ability to go lower and maintain travel.

The Flex Z's aren't perfect, but the dampers are very good for their price point, and the surrounding hardware is also good for the price point.


If you just want a bolt-in street based coilover that prioritizes comfort (and requires a high ride height to do it), the PSS are generally good.
