   | Hi AllWondering what the ratio is for rear springs
 By that I mean
 If you lower rear springs by 1 inch does it lower the ride height by 2 inches?
 Ie ratio 1:2
 Thanks
 J

   | Measure it.Pull it apart.
 Pull out the upper and lower spring rubbers.
 Put it back together.
 Measure it again and measure the rubber thickness.
 Divide the difference in ride height by the rubber thickness.....
 Theres your ratio.
 
 I've always worked out my installed height and spring rate needed and had them made to suit.
 Is exactly what the race car has.
 
 Read your sway bar question too and replied.

   | In case anyone interestedLower rear springs by 25mm translates to about 35-40mn ride height
 In old language
 1 inch lower springs drops ride height by 1 1/4 - 1 1/2 inches
 Cheers
