Hey guys

So I've been searching a bunch of honda/s2000 forums regarding this but I still haven't found a proper answer.

I'm looking to lower my car and I'd like it to ride better than stock or similar. The best setup (from what I've read) and also to keep within a budget is to order adjustable ground control springs with koni yellow struts.

My issue is that I need to supply the stockist with the spring rates I would like.

Do you guys have any suggestions?

I was thinking 380lbs front and 340lbs rear as this is the closest I can come to my AP2 setup of 256lbs front and 207lbs rear.

Any help would be much appreciated!

Another option would be Bilstein PSS which are cheaper than the GC setup but you don't get the Eibach ERS springs (guaranteed to have less than or equal to 2% variance in spring rate).

Doesn't look like you got your AP2 rates from here - https://www.s2ki.com/s2000/topic/818...nsion-springs/, which I think is the most accurate measurements of s2000 OEM spring rates (assuming you have OEM springs).

If you like the way your car handles now then try to keep the F/R spring rate ratio the same as it is now.

2004 - 2005 OEM rates are 262/278.

Also how low are you looking to lower the car? The Bilsteins don't have shorten damper bodies and I would imagine the Konis don't either, anything lower than 20mm and you'll probably be hitting bump stops quite frequently (on the rears for sure), which will affect how it rides - by how much I can't really say, depends on the rate of the bump stop. In saying all of that, the GC Koni and Bilstein PSS are probably your best options for what you're looking for.

Ah crap I looked a while for those spring rates I posted. Pretty sure they were from an old thread on s2ki.

Looking to lower the car around 1"? Reckon that will work ok without hitting the bump stops. And thanks heaps for the reply man much appreciated

Basically the less you lower the better, but 1" is 25mm so it shouldn't be a bad compromise.

what's your budget? There are a number of coilover options that ride better than stock and offer all the adjustability in the world.

Budget is around the $1300 mark

I was gonna go Bc coilovers but the spring rates at 10k/560lbs are way too high for me

springs rates don't say much about ride comfort in my experience.


What's your wheel setup like or going to be in the future? Reason I ask is that without upping your spring rate whilst lowering you will increase the chance of bump stops, wheels hitting arches, etc.


Anyway, with rates if you are starting with 262/278 then maybe look for rates around 400?

I couldn't agree more. My S2000 with 14k springs is way more comfortable than my 370Z which has oem suspension (~8k springs). It's all about the quality of the springs and the dampers.

BC coilovers will give you a very average ride regardless of what spring rates you put on them.

Ahh ok. Eventually going to be putting on rpf1 17x9 +45 all round.
