Good spring rate for daily driver??

[All_talk]

I need new struts so I'm looking a upgrading, I think I've got the fitment down, going on a '91 SS so '02+ WRX/STI right?. I was looking for some STI take off struts/springs but the "clunk" issue kinda scared me off. I've got a line on some low mile KYB AGX struts but was wondering how much stiffer I should go with the springs. I'm looking to tighten up the ride without making it unpleasent for daily driving, I know describing ride and handling is a bit ambiguous, so as a gauge I would consider stock SS pretty soft.

Anyway, I understand that the stockers are 132F/132R and was thinking about 25%-30% stiffer should be about right, so around 170 lb/in. Anybody running a setup like this? thoughts?

wagon rear springs are 190lb, those would be a good option
wrx fronts are 163lb, would make a good setup but you might have to play with cutting a 1/2 coil or so. (flames suit on )

Just found out the Prodrive '02-'03 WRX springs (not the P1 STI) are about 175/175 rates. But I think these are non-tapered springs and my '91 tops wont work, but the stock Impreza tops will right?

i have 150/160, and non-car-people passengers dont ask why my car is stiff. It's a remarkable difference from the stock stuff though. Been in a car with prodrives, and it is stiffer than mine, but still not harsh. That car was a bit underdamped. 210lb car ive driven was annoying on a choppy freeway- i was happy to get out. These all had about the same preload.

Having soft seats makes a big difference.

I think i listed the fitment issues with wrx stuff, and there are plenty of real experts that can help

For decades I've driven cars set up too stiffly and am not going to do it with this project. Standard spring rates on the
twgn are about right. Paricularly with whiteline bars,links
and bushings. Stiffer roll control with 20 front and the
adjustable 20-22-24 on the rear is very good.

The next step will be the same rate DMS double-progressive
springs with Tein adjustable dampers.
The result will be a compliant ride with plenty of dialed-in
stiffness when needed.

In reading Greg's question below, the DMS springs are available in standard ride height.

The double-progressive means that the final coils --top
and bottom are of thinner stock which provides some
compliance that helps when rallying on gravel
