NA6 NIB Sparco Spring - SoCal 909
Bought these brand new in box. They appear to be old stock. Never installed, zero miles of use. Paid 125 for them so asking for the same. Shiping should be no more than 15-20 bucks.

It has original manual form so I tried to look for spring rates, but could not find any info on them. Only came out with the below info if any one can determine spring rate from it. They are stiffer than stock, but slightly softer than Tein S-tech from my personal body weight compression testing.
Spring Type: Linear
Outside Diameter: 106mm
Wire Size: 10,75mm / 10,25mm
Spring Length: 235mm/275mm (f/r)
Max load: 625kg / 645kg
Total number of turns: 6,25 / 7,75
