Default 20/21 stock spring/strut measurment wanted.

anyone have their stock setup handy? , and wanted a ballpark figure on setting the lengths.
what are the stock lengths? center to top of plate would be easiest.

Are you talking on the car measurement because the spring rate when compressed will also affect the ride height. Measuring out of car will not be applicable.

With the way the car weight distribution is, setting up each strut exactly the same will give you varying measurements at each corner just as it is stock. I'd put them in and adjust ride height after you can gauge where it is after installation. From past discussions, I don't recall you can get factory ride height. (PD ?)

confirmed, you can't get hte car back up to stock height on a 20/21 with megans, they don't go high enough.

you can leave the rears alone out of the box but the fronts need to come up 2-2.5inches as a baseline

stock suspension lengths are irrelevant, the stroke and spring rates are too different.

What is the goal with your suspension?

ok, i just wanted to know the lengths, i have been working with suspensions for cars and bikes for over 30 years, i understand spring rates, valve dampening and linkage ratios, been revalveing motorcycle suspensions since i was 16. been making tubular control arms and 4 link suspensions for race cars many years now. just wanted stock lengths, thats all.
sorry to bother.

Wow...
Trying to help you best we can. We weren't doubting or making implications to your knowledge or abilities. Simply we didn't have a unit to measure for you so we are trying to help based on that.

You didn't specify which Megans and from our past threads they will not achieve OEM ride height. Typically speaking, buyers of Megan adjustable coils are interested in obtaining a lower ride height.
