FE1 and Z07(?) suspension differences...
Hey guys-
Got a quick question: What's the differences between the FE1 suspension and the Z07 suspension packages? I know there are different wheels and tires, and I have to assume different shocks. But what spring rates and anti-roll bars were used?
I have a '95 FE1, and would like to do some suspension work for autocrossing. However I want to keep the stock wheels and springs. Anyone have any recommendations for aftermarket shocks, anti-roll bars, and bushings?
Thanks!
Jeremy

That is a great question.
I think the Z07 suspension
has stiffer springs and shocks.
I know the Z07 has 9.5 inch
rims all the way around.
I have a 95 Z07 and it would make
a great autocrossing car,that is why
they offered the option.It handles
superb.

Here you go. This link has all you want to know, even differences between the years on the suspension packages.

FE1 is the base (soft ride) suspension. Here's a chart: http://www.idavette.net/susp_chart.htm
This show the different sway bar sizes, spring and shock rates and wheel/tire sizes

Thanks for the charts, guys! But they've brought up another question for me: in 1995 theres a FE1a and FE1b for early and late in the model year -- how do I tell which one my car is?

The charts are good but they show the N/mm rate of the springs. Does anyone know what the conversion is to SAE? Vette Brakes and most after market suppliers rate their springs in SAE.

According to this site http://www.bekaert.com/weldmesh/conversi.htm you take the n/mm figure and convert to kgf/mm by multiplying by 0.10197. You then take that number and multiply by 1422.3 to convert to lbF/in.
I don't think it is straight-forward.
[Edit] And the other thing the Z07 cars have is a higher durometer rubber bushing in the lower control arms. Replace bushings with urethane and you are good to go.....

Re: FE1 and Z07(?) suspension differences... (Joe90)
To convert newton/mm to lbs/in:
(spring rate, N/mm) * (25.4 mm/in) * (0.2248 #/N) = (spring rate, #/in)
So multiply the spring rate (given in N/mm) by ~5.71 to get into #/in.
