MY 07 GTB standard suspension

[Maxi]

Gday Guys,
Hoping some of you can help with some knowledge of springs.
My 07 GTB wagon IMO is a little to soft in the suspension department. I love the static ride height however when loaded up it just sags to much for my liking.
King springs make the KSRS-29 which they says is standard height + and is 20% stiffer. This would suit my needs however there is no front replacment from King springs. Does anyone know a spring set front and rear that is a little stiffer than standard with similar ride height or 10-15mm higher
Plenty of info on lowering but nothing on standard replacment springs
Cheers

How many km's are on your current suspension? Could just be shagged

Thanks for the reply, Only 84,000km on the stock suspension. Its still looks like the factory ride height compared to similar models

Hi Guys,
I will soon be upgrading the rear springs to KINGS KSRS-29. I will be doing a write up on the process so hopefully it will become a sticky to help future people doing the same or similar setup.
I am going to be taking measurements of ride height and springs to compare etc before and after.
Can someone be kind enough to measure the FREE length(off the strut) of there standard Spec B rear springs(wagon) if they have them lying around. Maybe even some info as to how many KMs on them. Just want to compare so when I can take mine out to see how much they have sagged.
Cheers
