Differences in stock springs

[Garido]

Hi all,

I have a large range of stock springs for NA and NB. They are distinguished by either height or a coloured dot on the spring.

Is there anyway to confirm which spring is for what strut/shock and or top hat.

Pretty sure there was a post in the last few years on this, & think manga_blue contributed to it. Found following I squirreled away in the Clubman FAQ, but I'm sure we've touched on the coloured dots & what they correlate with.

Early NA6 164/97 lb/in with 19/12 mm sways
Later NA6 154/94 lb/in with 19/12 mm sways
Std NA8 154/94 lb/in with 19/11 mm sways
NA8 R package 154/94 lb/in with 20/11 mm sways, but that might have been the US version only
All NB 162/118 lb/in with 22/11 mm sways
NB Mazdaspeed 215/158 with 23/14 mm sways (presumably the same on the AU delivered SE?)

Just going on those figures alone the first model NA6s had the sportiest handling (lowest FRC of 58.9%) then they got progressively worse from there until you got a Toyota Corolla-like 66.9% with the stock NB.

PS divide lb/in by 55.88 to convert to Kg/mm

Thanks. I'll have another search around but need to find what coloured dots correspond with what rates.

thank you again for being so helpful. I've also bookmarked the thread for future reference.

Oddly enough, the rear spring is taller in height than the front spring. I want to continue playing around with spring and swaybar combinations.

Considering the springs all vary in age (some maybe 30 years old) there would be sagging, etc and may have outlived their useful life.
