Roush Spring Rates

So I just bought some Roush springs from BlackcatN20. (thanks btw) And after a lot of searching I couldn't come up with any spring rates for em. Nobody knew, people guessed, and people said Roush didn't know or didn't want to tell. Well I thought I would try my luck and email em. I will just post the email.

"I have a set of Roush springs for a 00-05 Focus. They are blue and I believe the part number is R06000002. I was wondering what the spring rates of these springs are. The rear springs certainly appear progressive whereas the fronts do not. I would really appreciate the info. Thanks a lot
-Justin"

Their response.

"Justin,

Here are the spring rates for the front and the rear:

160 lbs/in front
188 lbs/in rear"

This was from rppcustomerservice@roush.com.

So it seems the spring rates are above. Just thought I would let ya know and perhaps we should update the suspension reference thread with this info.

IIRC, they are rebadged Eibachs. Roush never released the spring rates.

Thats one of the things I read. I also heard that they were rebadged progress springs as well. Neither were ever supported with concrete proof of by someone who actually worked at roush. I am pretty confident this is the right answer. The only mystery is why it would take them till now to answer the question of what the spring rates were outright.

They are most likely made by well known spring manufacturer, but probably to Roush specifications.

They're within a few lbs/in of Eibach Pros so not that low. I'd refer to them as be in the moderate range.

They are about 30 lbs higher than the SVT's and an inch lower. Why do you say that? Do they feel stiffer than that or something?

Strange. Don't you have a gutted interior? I don't see how you would bottom em out with nothing in the car. It probably rides a lot higher without all the weight in it too.
