I bought these used and had them on for about 5K miles before upgrading to coilovers. I don't know the mileage from the previous owner, but they are in good condition. Spring Rates: F=345, R=438. Drop: F=.75", R=1". These springs are designed without a taper at the bottom like most, so they don't fit the lower spring mounts perfectly. Many people have run them without problems though. I used some polyurethane spring isolators as a precaution to prevent them from sliding around. Seen below is how I used them on my Koni shocks. I'll included the isolators so you can use them if you choose.

Located in Nashville, TN for locals.
This is on my autocross setup - 275/40/17 tires, which are shorter than OEM diameter in the rear so there is more rear fender gap. Also I had 0.5" cut off the rear spring mounts.
No interest in one of the few linear rate springs available for the Z? Lots of people run these as-is with zero problems. I was just being extra cautious with the poly isolators since I've had trouble with squeaky suspensions in the past.
If i run them as is, i.e without any new struts and all, will I be okay? It's a 03 Z. My winter set up is stock 18" with regular tires and for summers I run 20" rims with 245 up front and 275 tires in the back, if that matters.

They'll be fine on the factory struts. The spring rates aren't so much higher than stock that you would have issues with them being under-dampened and bouncy.
