shock / spring upgrade... on the cheap

SS_Firehawk

Higher spring rate is because of the divorced spring design. The spring lives closer inboard and requires a higher rating to resist the additonal leverage compared to a true coil where it's at the shock tower. You'll kill your suspension geometry.

This is the answer i'v been looking for. Thank you.

So this would mean that if you don't get a true coil you don't want a much lower spring rate in the rear. So a difference like 12k/10k wouldn't be idea. It would be more like 12/11?

Just trying to get a better understanding on it. Thanks in advance!

You can go whatever you want, even 12/6 oem style, but the handling will be different, the car will understeer excessively. As I remember stock is like 8/8 or stiffer rear, which still understeer a little but becomes perfectly balanced with front negative camber. So, for companies, they use the motion ratio to get the perfect front and rear spring combo which will improve or preserve the handling characteristics.
