Stock Spring Information

[silverton]

I'm sure the mods will be able to clean this up and make the formatting better, I don't quite have the experience with writing technical threads, but I figure since this doesn't appear to be all in one place, that it would be nice to have a Stickied Thread!  This is, of course, for USDM models, and the information is straight out of my 1988 FSM.  It includes information on ALL US models, including those with the ca20 engine.

All figures are "mm (in)" just like in the manual.  This should be a given, but I know there is still a lot of confusion, the left and right is orientated as though you were sitting in the driver seat, looking out the windshield.

Front

Coil Diameter

• All Models - 150 (5.91)

Wire Diameter

• Left
• CA20E GL Hatchback - 12.3 (0.484)
• CA20E All Other - 13.0 (0.512)
• CA18ET - 13.2 (0.520)
• VG30E - 13.6 (0.535)
• Right
• CA20E GL Hatchback - 13.0 (0.512)
• CA20E All Other - 13.0 (0.512)

• VG30E - 13.7 (0.539)

Free Length

• Left
• CA20E GL Hatchback - 311 (12.24)
• CA20E All Other - 334.5 (13.17)
• CA18ET - 284.0 (11.18)
• VG30E - 301.0 (11.85)
• Right
• CA20E GL Hatchback - 330 (12.99)
• CA20E All Other - 344.0 (13.54)
• CA18ET - 291.0 (11.46)
• VG30E - 307.5 (12.11)

Spring Constant (Spring Rate) N/mm (kg/mm, lb/in)

• CA20E All - 21.0 (2.14, 119.8)
• CA18ET and VG30E - 29.1 (2.97, 166.3)

(Interesting note, FSM has a typo and shows the lb/in rate as only 116 for the CA18ET and VG30E models, a quick google conversion of the other two listed rates got the proper lb/in

Temporarily Sticking this information.  I will come back and re-format the thread a bit in a little while.
