CLK63 Coupe\Convertible front Coil Spring height specs (209 321 0404)

Hi guys, I'm looking for specs regarding the CLK63 Coupe\Convertible front Coil Spring specs (209 321 0404) I'm looking to raise the front height of the car without going soft with any of the other front coils from 500s 550s etc.

I have measured on my convertible 15mm of thickness , the outside diameter is a known 170mm, but what about its height? any input on that? n.b. 63 coils are different part number from clk55

Does the Clk55 ride higher than the Clk63? (knowing weight is similar)
