[QUOTE="bigmoose, post: 8159238, member: 64149"] that only shows the SRA rates. here is the info direct from an eibach tech for the eibach springs: So i bought a set of eibach pro springs off here and was told they were for the 03/04 cobra, well after talking with an eibach tech i found out they are not. here is the good info i got: 99-02*: kit# 3590.140 Front spring #3510.301 Front spring rate: progressive 456-571 in# Rear spring #3590.002 Rear spring rate: Progressive 651-822 in# ---------------------------------------- 03/04: kit# 3594.140 Front spring #? Front spring rate: progressive 456-571 in# Rear spring #? Rear spring rate: Progressive 536-822 in# He also noted that the spring lengths are different for each kit. If i installed the 99-02 kit in my 04, the front will sit ~0.5" higher than it should and the rear would sit ~1.25" higher than it should with the proper kit. i forgot to ask the actual spring #s for the 03/04 so if someone wants to post them that would be helpful. I just installed the 99/01 kit in my '04 and i think it sits perfect. the front dropped about 1/2 inch(all stock isos) and the rear about an inch(top isos out). the car sits nice and level now.
