i know of the stechs drop, im just saying I will let you guys know exactly what the drop range is since clearly in the rears its not 3" range as they claimed
#1603
just got off the phone with Megan Racing, apparently the thread length is not linearly proportional to the drop
so you have to set your own baseline and then measure the drop and go from there

Since there r way too many dips around here ill only be dropping it .5 front and 1" rear but I will drop it to the lowest just to see how it looks. When I'm back in NH ill drop it prolly 1.5 front and 2 rear
Btw I don’t care about being close to the ground, what I find attractive is 0 wheel gap, that was one of the reasons why I bought bigger tires. My tires reduce the wheel gap by 0.2”!

it was actually dusty as ____, I guess the camera aint good enough to pick up the dirt lol
but it mostly California...it doesnt rain here but if u saw my car in person ud see a ton of scratches since paint is crap. I havent waxed it since october and 2 weeks ago was first time since then I just use california duster to sweep off dust/pollen
btw i puke in my mouth a bit every time I look at this disgusting wheel gap

The height adjustment is very predictable front-to-rear. Since the front is a Macpherson strut and is pointing to the center of your contact patch therefore that will be 1:1 (minus the cosine of the angle the struts are leaning at). Now take a look at your rear suspension…if you are very astute, you will notice that the spring is just about at the center of the lower suspension arm…swivel-point-to-swivel-point. That is the ratio you will get when you set the ride height…that is why they have only half the range of the front. All is good…You will get twice the change at the rear wheel from the “lever-arm” action. I also think that Megan screwed up…all the other manufacturers have twice the spring rate rear-to-front – and that “lever-action” is the reason for it. And that is about right for the car from a dynamics point of view. Megan does not! Their spring rates are identical front-to-rear. I’m going to predict that in a high speed corner when you hit a bump or a dip in the road, your car will pitch back and forth like on a hobbyhorse with Megan’s identical spring rates…well, maybe you won’t even need to be in a high speed corner. Now the manufacturers that make a true coil-over (TEIN for example) for the rear, their spring rates should be the same – the spring reacts at the end of the suspension arm therefore no “lever-action”.

"(minus the cosine of the angle the struts are leaning at)"
angle between the vertical and coilover? then it results in something close to ~0.8-0.9" which seems pretty close
TEIN is not a "true coilover" in the rear, same setup. separate spring and shock for the basic and street kits
this shows 6kg springs as you mentioned:

this shows the construction of the rear on the last page(pg10)
http://www.tein.com/tech_info/inst/2q30u.pdf
have you seen them in person? how did you come to the conclusion that rear is a true coilover?
we know for sure that the basic kit has separate spring and shock from here:
