This is a side by side comparison of the differences in just changing springs.... Swift Springs ARE basically the best springs on the market and this is why just upgrading the springs will REALLY help those MR coilovers....
Although this is for mini's they use the same diameter shock tubes....
In the end....
MR Coilver Springs are:
ID = 62mm
height =
180mm front
200mm rear
8/6 for street coilover series
12/10 for track coilover series
Replacement's use ID 65mm (Confirmation from Swift themselves) and retain same specs, but from all the research I have done, S13's weights are lighter, so I would go 10/8's...

Well I posted on another thread that I would in detail explain the substantial difference between Swift springs, and all other springs. So here it is.
I really don't know where to start with this but Ill just jump into it.
I have tested out many different types of suspension systems. One of the biggest factors in the entire suspension system is of course the Spring.
There are a few factors to look into when it comes to springs.
-stroke
-accuracy of spring rate
-weight
Now I'm sure most of you are aware of the spring binding problem with megan and the BC coilover system. Well that is completely a spring issue, most companies totally cheap out on the springs of the suspension systems especially the more inexpensive ones.
I have dynoed pretty much every springs I can get my hands on. So I can show you the differences of them. ......
