tein flex 7k front springs on the rear?


if i put the 7k front springs on the rear, will i be able to achieve a 11.5quot; hub center to fender?

I would think that at 12quot; your A arms will be contacting the frame and it won't be possible to lower it any more. And that's provided that you have NB, FCM or FM rear top hats. At 11.5quot; I would expect your Mia to ride like ass.

That would depend on the lenght of the springs, and if there's enough adjustment left in the shock body lenght. Typically the front springs are longer than the back, I know of one application that the longer springs were used in back, he didn't seem to have any problem with his 12 1/2quot; ride height. Bob

Flex units have pillow ball mounts, meaning the other stuff you mention is not needed.
Also, Flex have threaded shock bodies for the ht adjustment. While the spring perches are adjustable, you set those for proper spring performance (off the bumps) then adjust the ride ht with the shock bodies.

I have 8quot; free length 6kg springs in the back of my NB that used to be on the front.  Went from 6kg f / 4kg r to 9kg f / 6kg r.  Fits and works well, but I'm at 13quot; ride height in back.  I'd say I could go down maybe 1/2quot;, but beyond that I'd be out of room to shorten the shock body any more.
BTW - I'd think again about trying to hit 11.5quot; static ride height unless you're building a show car.  That's just too low for the suspension geometry to work right.

I'm all for lowering a car but I believe anything below 12.5 inches and you will have a pretty harsh ride. I am at 12.75 with 350# springs on the rear and it's about as stiff as I'd care to be driving for and long distance. Brad's right though if you are building a show car than buy all means go for it. There are a lot of Cali boys that can not fit a key standing upright between the road and their pinchweld.

1st question - why?
they will be more receptive to slammed rides

Not to mention his steering geo will be all outta wack to. He'd have to buy different tie rods to keep his steering geo in line. Lowering is one thing but you have to do it right or you'll lose more than you'll gain and I don't mean just ride height either

If he really wants to build a quot;low riderquot; all those geometry issues can be addressed. The car will still be a nut buster to drive but who are we to say he's wrong.His dentist will be happy his chiropractor will be happy and if it makes him happy whats the harm. Personally not my choice but then I don't have to live with it.

I just like going fast!

Then you shouldn't have bought a Miata  Now if you like going fast around curves and cones then that's a different story.

Who said it had to be in a straight line?  It helps to have 14psi of 2560R compressed air feeding the little guy

Now back on track ...........scsi let us know how your build goes. Include pics if you take them
as well and i've seen what those guys can do.  i love miatas in both slammed form and race prepared form, and i'd like to get my car somewhere in the middle of that lol
thanks so much guys for all the responses so far! keep em coming!

I think you'd be better off not moving the front springs to the rear. Those are pretty stiff. You are aware that the lower shock body is adjustable as well as the spring perch to give you more ride height as needed.

You car is not handling the way you like because you are too low.  You are going to have to pick - a competitive CSP car and a slammed Miata with no suspension travel aren't synonymous.

The compromize is 12 1/2quot;, below that you change the camber curves, and run into bumpsteer. Bob

Sent you a long winded PM. Just because they are slammed doesn't mean they drive worth a crap. Any idiot can throw away the springs and ride on the bump stops.
guys also recognize their cars dont handle well.  they also recognize their cars arent comfortable and the hardships that they bring on themselves, which is why they can laugh about it.
im not looking to be quot;slammedquot;, my car isnt tucking tire or anything, ive got about an inch gap between the fender and tire.  i like the look of the car at the height i got it at.  i dont want to go lower, and if i must, i will raise it.  all i'm saying is if i can possibly keep it at the current height, that would be cool, if not then oh well.  that is the only reason i'm asking if i can get the 11.5quot; ride height w/ the length of the front springs in the back.
thanks Thumper for the PMs, but i think you misunderstand my position.  also, i plan to put the STOCK 7k front springs in the rear, not the 10k.  i want to buy 10k springs for the front, and move the stock 7k springs to the rear.
thanks again everyone. more feedback is welcome of course!
