Hi Guys,

Anyone know the stock DC2R spring rates.

And how the hell do you convert kg/mm to XXXlbs? :confused:

To convert from kg/mm to lb/in multiply by 56. To go the other way divide.

Eg. 24kg/mm = 24*56 = 1344 lb/in

Imagine them going over some train tracks, you'd probably do a 360.

Thanks fellas.. going by what tank has posted we're talking about 4.5kg/mm for front and back!

I always thought the fronts would be stiffer?

I currently have kg/mm springs in my car and they are 6.5kg/mm front and 3.3kg/mm in the rear.
