These are off some ground control coilovers. Can someone verify what the spring rate is based on:

Eibach 72717 GC180.64.44 &
Eibach 72734 GC200.64.67

Thanks for your help!

 

Well, I'm no expert, but I would say that the spring rates are those 'middle' numbers, 180 & 200 respectively. If so, then those are certainly too soft for our cars(atleast 3rd gen tegs), maybe they are not intended/made for our cars, maybe they are for some other car?...who knows. FYI, 3rd gen teg rates are 212fr & 117rr.

 

GC180.64.44 -- the part number indicates a spring-rate of 180mm length, 64mm inside-diameter, 44 spring-rate (Newton meters -- multiply by about 5.7 to get 250 ft./lbs.).

GC200.64.67 -- so this is equal to 382 ft./lbs.

 

ok, now those numbers look a good bit better for spring rates.
