OEM vs Eibach vs Ark Spring Rates

[AA95101]

If anyone is interested I crunched some numbers for spring rate comparisons.

Everything is in lb/in and the percentages are based on OEM top values i read on this forum

Ps I received the spring rates for the Ark GTS spring directly from arks customer service. For whatever reason they don't publish these values

OEM:
front: 172
rear: 489

Eibach:
front: 195 (+12%)
rear: 331-565 (+14%)

Ark GT-F:
front: 179 (+4%)
rear: 274-324 (-33%)

Ark GT-S:
front: 162 (-6%)
rear: 386 (-21%)

Hope this helps someone, cheers

Great info, thanks. interesting the ARKs are actually softer in the rear, by a good bit. that would explain why I didn't feel a difference in ride quality.

Nice work. I would be interested to see the H&R RWD specific lowering springs added to the comparison.

I don't understand anything. Can anyone tell me which of these is the stiffest one?

I had a thread for this on here somewhere but it's continuously buried, Springs, Coilovers & spring rates? What do our current options have?

Where did you get the specs for the Eibachs? Techsupport?

I found the values for the eibachs on another thread. I didnt verify them independently. So I would take any of these numbers with a grain of salt
