i bought a set of use mugen ss without springs. you guys think the tein s springs be a good replacement?
Kind of... while the concept you posted applies to a springs in general, once they are attached to a car it really stops meaning anything useful. To get better data we have to take in to account both the motion ratio of the suspension that the spring is attached to as well as how much weight that suspension is holding. The 1st one gives you whats called "wheel rate" which is the effective spring rate acting at the contact patch of the tire. It will be, in nearly all cases, Less then the springs normal un mounted rate. the one time it can be greater is with cantilevered suspensions, such as those found on F1 cars. On this car the front motion ratio is ~.9 where as the rear motion ratio is ~.5... which means that only 90% of the front springs actual rate gets used; so if your front spring rate is 345 then your wheel rate is 345x.9= 310. Alternately on the rear where the motion ratio is .5 your 480 spring rate drops to a 240 wheel rate....
So while initially the front spring is "softer", when put on the car the front end actually ends up with the functional stiffer spring. And we haven't even taken weight supported in to account.
What are the spring rates and drop rates on the RSX-S A-Spec Suspension Kit for 2002 - 2006?
There's actually two different A-spec kits. One for the 02-04 RSX and one for the 05-06 RSX. The 05-06 kit has reversed springs in the front and is assumed to be slightly stiffer. Acura has never officially released the spring rates so no one know for sure. The only thing that is certain is that the springs are progressive meaning that they are somewhat soft under normal load and get progressively stiffer as they compress. I assume that the A-spec spring rates for the 02-04 kit are very similiar or maybe even identical to the 02-04 DC5 Type-R spring rates which are:
2.8 to 4.6kgf/mm front
3.0 to 8.0kgf/mm rear
I haven't been able to find the spring rates for the 05-06 DC5-R.
There's a lot of speculation that the A-spec kit is just rebadged Type-R suspension for the US market.

I would agree only from what I've read that they are the same. I happen to have early A-Spec springs and RSX dampers that I keep threatening to sell... very nice condition.
This is an old list. I've had it for 5 or 6 years and it was older than that. Don't know the original author's name. It has numbers I haven't seen anywhere else.

[What is Progressive Spring Rate?]
Progressive rate springs are likely
any way to tell if your dc5r is 02-04 or 05-06?
Iirc, 05/06 RSXes have the front right spring wound opposite of the other three.
