[Ward Hill Press]

Anyone know what the spring rate is? It may be Euro, or listed as an
upgrade. Anyone running them? I forgot I bought them. 54010-U0110

AI says;

The Nissan part number 54010-U0110 corresponds to a heavy-duty rear spring with a rate of

116.5 lbs/inch. 

 

This part was designed for the S12 chassis, which is the Nissan Silvia/200SX from the mid-1980s. It is part of Nissan's "HARD" spring lineup, a designation used for their performance-oriented parts."

 

Stock 510 fronts reported as around 90#/in.

Fwiw, the  "hard suspension" 510 F/R spring rates are 116.5/443.1 #/in.  Stock are 89.5/357.2. This per '72 Service Manual. A note in the 2001 Comp Catalog suggests cutting 1 1/2 coils front and 3/4 rear for a nicer look.
