I have a set of Ground Control coilovers for a 2nd gen MX-6 or Probe.
The fronts are used but in good condition and the rears are brand spankin new.
I believe the spring rate is 375/225. I will double check that when I get home.
I will also post pics once I get home.
The fronts are used but are in very good condition. The collars turn easily once loosened. The rears are brand new.
They are $250 plus shipping. Shipping should be around $20 for most of the states.
Also- New ones go for 380 plus shipping. the few times ive seen them sold used (mind you, all four of them used) they sold for 200. so i think this is pretty good gosh darn deal.
You say you think the spring rate is 375/225, but how can you tell? Also, what numbers (model numbers?) are printed on the springs themselves? I have a used set (off of eBay) that I have yet to get on my car, and I'm curious to see if I got the right ones and make sure they are what they are supposed to be. By the way, yours look great!! Look 5 times better than the ones I got! Mine are a little dirty to say the least!

how do you tell by the 3 sets of numbers thats on the coilovers whats the actual spring rate...F 150.64.66 R gc 180.64.44
First number = spring length in mm
second number = spring diameter in mm
third number = spring rate in kg/cm (note that on GC springs, the number is shown as kg x 10. You have to divide by 10 to get the right number)

You can shortcut the math a bit by doing (kg x 55). Its not as accurate, but its quick-and-dirty close enough.

Thanks for the model/part numbers Gavin. That's what I have too. I suppose I could have called or emailed GC direct, but I kinda forgot about it until I saw your "for sale" thread.
Man!!........the math was stumping me there at first until I figured out that it must be kg/(linear)cm and not (square)cm. I must have been scratching my head for 45 minutes on that.
