Troy, can you do me a favor? Even if you've already done it, can you re-measure the diameter of the front and rear spring coils in millimeters? To the closest 0.1mm you can do?

Default measurements of springs..

Sure, I just did this last night for Pat...

FE1 rear spring, , .549" dia. roundstock (14MM)
F41 rear spring, , .570" dia. roundstock (14.5mm)
F41 front spring, .626" dia. roundstock (16MM)

Does this make sense? Also, I have been told that the FE1 can actually have a couple different springs.. Can anyone elaborate on this??

Thanks, Mike

Troy, I suspect you have a mutant on your hands. I believe your front springs are 16mm, which puts them at the low end of the F41 scale. Your rear springs are a different story. They are almost certainly FE1 or MAYBE FE2. That'* a serious mismatch. I suspect that someone changed the rear springs on the car at some point.

As a point of example, my springs are 16mm and 15mm on the SSEi. And I have the advantage of ELC in the rear. That 1.5mm mismatch would make for some pretty interesting handling in my mind. I'm no expert, but That'* what I have on one of my cars for a comparison, and it'* listed as FE2, not F41.

Maybe it'* more about spring constant than diameter. Do they test them after manufacture? That might explain the diameter differences.

Default WOW!

Interesting stuff!! The F41 car clearly states "F41" on the trunk tire cover, and the VIN on that cover matches the dash plate, but Iike I told Pat, the questions / measurements he is requesting are good ones and very welcomed, as I bought the F41 car used, so who the heck knows what has been changed. The springs out of the so-called F41 car are thicker than the FE1 car, and I know the FE1 car is original.
So, do the numbers sound right on the FE1 car? Any other thoughts? What about the front springs on the F41 car?

thanks for all the info.. VERY interesting!!
