Hi All
Wondering 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

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 interested
Lower 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
