SPRING RATES & DROPS: ALL IN ONE THREAD!!

[vpec13]

I'm not sure if this has been asked. But I have a new to me 2015 Mustang GT with the performance package. Are the stock springs linear or progressive?

Linear. Rates 165 / 728 lb/in front, rear respectively.

Anybody know EB and V6 spring rates?

how do we still not know this?

I have a set of ecoboost PP springs in the garage.
I'll sit my fat ass down on each and have my wife measure the deflection. More to come.
(full disclosure: I have a skinny flat ass, but I can still do the math.)

Someone needs to update the spreadsheet. Drops and spring rates are wrong for some of the aftermarket aprings (specifically bmr handling).

Just go to page 9

Thanks for that.
Someone should add this to the first post and/or consolidate the 2 into one workbook.

Hey guys, I've been out of the loop on keeping up with the spreadsheet, but if you guys still use it and want to have edit permissions, just let me know and I'd be happy to share it with you. I can also just send you the spreadsheet if you want to upload it to your own Google drive and share. PM me with any requests. I apologize for the lack of communication on this in the recent past.

Also, thanks BmacIL for taking it a step further. Awesome work man!

I may have been looking at an older doc but I can not find the rates for the pp2 springs. All CJ pony lists is that they’re 20/13% stiffer. Anyone have the actual rates?

I thought it might be a good idea to compile all the spring rates of the springs of the market all in one place, I shall keep this original post updated so people don't need to read all the replies.

Linear VS Progressive

You might want to add some description for dual-rate springs, though it'd be a little more complicated than calling them something partway between linear and truly progressive..

Now I see why you recommended I remove my base 19 struts/shocks if I do the 763’s

Yes I could barely get away with doing that but like you said going with the Ford Tracks or the Bilsteins make more sense

So between the Tracks and the Bilsteins what the difference, I see u run the tracks

Both are excellent. With the SP763 I'd probably go with the FP track. Up until recently the Bilstein were not regularly available so it was the FP by default.
