Good question mugen_ctr - to tell you the truth I don't know the spring rates... more research lol!
According to this:
http://www.springrates.com/catalog/H...ive-Springs-EK
Spoon Progressive Springs provide a 0.8inch drop front and rear.
This is a similar height difference when looking at using EK9 Shocks/Springs vs. Stock EK1 on an EK1.
Ok guys, while maths is not my strong point I've been able to source some spring rates in lbs/in and convert them to kgs/cm so we can see how stock ek and EK9 spring rates compare to Spoon and a variety of other aftermarket springs on the market:Quote:

Good morning lads,
I've received a quote from the NZ performance website FortyOne Automotive (didn't get a reply from other one) and they've come back with a really good price on Spoon Sports Progressive Springs for EK Civic:
$341 + either one of the following shipping options (was quoted to Wollongong, NSW):
AU$129 - EMS Air 1-2 weeks
AU$119 - SAL Air 2-3 weeks
AU$70 - Japan Post Ocean 3-6 weeks
So you can get these springs to your door in about a month for a little over $400. Not bad at all :D

I think I'm going to go for it - would I need someone to install the springs for me or is it something you can do yourself/need special tools?
Very nice info there!Quote:

Does Spoon 6.5 front compared to CTR 4.3 front equate to much difference in terms of ride comfort?
not massive, but the CTR will be more comfortable.
But if im paying money, i would get the Spoon..
actually.. fark them all get the eibach sportlines
yeh, it's pretty hard to find EK9 suspension in Oz - think there is one going for $450 and would most likely need to be re gassed (if it can) and springs probably at the end of their life anyway + you don't know what you're buying, past life etc etc so might end up spending more which is a bit pointless... so agree better to get brand new
A really really good article/tips on buying suspension presented in a light and easy way to understand. Highly recommended.

You can do it yourself with a mate. Tricky (and dangerous part) is separating springs and shocks. There are heaps of DIYs out there. All 1996-00 Civics are the same.Quote:
