Version 5/ 5Zigen combo
FHI Version 5 Struts/ 5Zigen spring combo
This is a very popular combination in the US. The FHI version 5 struts are a 36mm piston, inverted strut that is designed by Bilstien and built by KYB in Japan. The 5Zigen spring is actually manufactured by a company called KG/MM in Japan. They are a progressive lowering spring with rates of 169.3-225.7 lbs/inch front and 79-180.6 lbs/inch rear.
Adjustability: Non adjustable but will drop the car anywhere from 1.25 inches to just over 1.5 inches
Price: This combo could be purchased for around $550 total, but the struts have just increased in price.
Review: I have this system on my car and it has been there for just over a year. I have raced in autocrosses several times on it, and it has been on many brisk mountain drives as well. It is a bit overdamped in the progressive springs, so the daily ride is a little harsh, but they handle on a track extremely well. The car corners extremely flat, and cuts crisp and clean, almost go kart like. Again, if your local roads are bumpy and rough, and the car is a daily driver, you might want to look elsewhere. But if autocross is your thing and you are on a tight budget, this combo bears some serious consideration.
