I want to know, for those who have/had these springs, what some good shocks/struts are to make my car handle well.

 

I guess what it boils down to, is what are you looking to do w/ the car, and how much are you looking to spend. Tokico Illuminaz are sweet and so are Koni Yellow's. I know the Tokico's are 5-way adjustable, I'm not to sure about the Koni's but it wouldn't surprise me if they were. Again, i know both come w/ life time warranties on the original owners car.

My bro has the illinunaz on his civic, it's a nice ride.

 

Because S-techs are such a soft spring even a budget/oem upgrade shock like a tokico HP (blue) will be able to handle the springs. I would say on a budget, you should go with KYB AGXs. Best bang for the buck. And you can find them on Egay for really, really cheap.

next thing would be to invest in some sort of bracing (strut bars), camber kit, and roll bars. Upgrading to a ITR rear swaybar will improve your rotation better then anything else.

 

I've never had the Teins but I have Eibach springs with a set of orange KYB struts and I'd recomend those KYBs to anybody.
Before I had non-adjustable Tokicos and the ride is far far too harsh for the roads here. For months I didn't even want to drive this car because it felt like I was damaging my frame every time i'd hit a tiny bump.
Anyway the KYBs are far more comfortable and handle every bit as good as the Tokicos; best aftermarket suspension i've driven on.
It all depends on whether the roads are as bad in WI as they are in OH.
