So i called a store to give me a quote on a set of TEIN Basis Coilovers and they said the spring rate was 448 over 8 Front and 224 over 4 Rear. What do they mean by that?

 

448# front
224# rear

or

8k front
4k rear

I believe they gave the standard and metric rates

*****edit

found this in the Progress for sale thread

250 #/in. = 4.5 kg/mm
350 #/in. = 6.3 kg/mm
450 #/in. = 8.0 kg/mm
500 #/in. = 8.9 kg/mm
550 #/in. = 9.8 kg/mm
600 #/in. = 10.7 kg/mm
650 #/in. = 11.6 kg/mm
700 #/in. = 12.5 kg/mm
750 #/in. = 13.4 kg/mm
800 #/in. = 14.3 kg/mm
1000 #/in. = 17.9 kg/mm

 

OHhhhhh gotcha thanks

 

Spend the extra $50 and buy the street advance.
