Finally! 
the ccv2 is the number on the back of the card in the signature area. it's usually like 3 numbers.mtlm3 said:Hey draxas,
Thank you VERY MUCH!!!! I've anxiously been awaiting lowering spring. I have a question though, I'm placing my order and in the section where I fill in my Credit card info, it asks for "ccv2", what is that? I don't know what to enter in that field.
H&R are already outsweetdeath said:I wondering why they arent progressive... do progressive spring isnt superior ? I like to know more about that before buy them... or maybe wait for other compagny to make some like H&R, B&G, Apex...
The H&R springs are listed as 1.3" Front and 1.2" Rear ....Part#51643sweetdeath said:M3-GT man... though choice I wanna lower it, but how can we take a decision between Eibach or H&R... H&R seem to be progressive, but they tell it lower suspension 1.5 to 2''... and the other is 1.2''-1.4'' and that seem enough for me since I wanna use my car in winter...
Care to do a quick explanation of what linear, progressive, 160 and 171 mean when applied to springs?Draxas_VP said:I finally called and spoke with a Tech at Eibach, and he says the springs are Linear, not Progressive.
he said the spring rates are:
160 Front
171 Rear
I hope this person is correct though...
