yeah looking again it seems to be about 1.5" or so.

so. 4 + 1.5 = 5.5"

so oem = 5.5"
7" 250 = 4.8" (plus helper = 6.3")
9" 220 = 6.5"

the 7" 250 would be the safer choice unless there were a good 1" of threads left to go lower. I have a feel there would be, considering the images I posted before showed a slammed car (on ISCracing tophats) with plenty of room to go lower.

I've been one of the weenies talking about spring rate changes too.

My question is: What is the benefit of going with a 9" without helper vs a 7" with helper if the spring rates are the same?

My thought here is that I want to buy the most effective, stupid cheap *** setup, and not have to go back and buy new cheap springs after I'm done.

With the NA kit's 400lb front, I'd prefer the 220 or even 200 rear, but it's not that easy to find. With 400/250 and stock sways (19mm/11mm) I see a FRC of only 53.7% - not stellar, but way better than the 46.0% of the RL 400/350 kit.

If I could find 200's I'd see 58.7%, pretty damn good, no disconnected sways, no buying super stiff/ expensive tubular sways, ect.

If I could convince RL to send the 425 fronts instead of the 400s I'd see 55.0% with the 250 rears. Closer, not perfect.

If anyone knows any more inexpensive sources for 7" 2.5 springs please shout em out!

less chance of coil bind at higher ride heights. that's about it.

QA1s are as cheap as you are going to get. Hyercoil, afco, and eibach are all over $60 each spring. otherwise start living on ebay.


there's a set of 5 kg/mm (279#) 8" springs on ebay for $60 shipped...best i can find right now.

oilstain

Reduced risk of coil bind, well damn, that makes sense.

I'd go with the QA1s if they had a 200 or 225 ish. the 250 is still a bit much for the 400 front. I'm emailing the poor folks at RL again, this time asking if they'd throw the 425 in to the NA kit.

We'll see.

if they didn't ship from china with 425s, you're not getting them. ask what the difference between NA and NB kits actually is besides the rates.

I'm going from a 550/300 setup to a 400/250 setup, but I have a 7/8" front sway.

oilstain

QFT, doesn't hurt to ask though.

56.9% with stock 11mm rear bar. Not bad at all.

I'm trying to find a racelands + 2 cheap springs to use with my stock sways so I don't have to buy any other new parts. I also just enjoy researching crap like this.

Edit: CRAP, I just read somewhere that if lowering the car, I should get adjustable endlinks for the bars. Even for cheapies thats at least another $100. Any rules of thumb as to when it's necessary: like ride hight 14" = fine, 13" = tons of preload, 12" = don't give a crap about handling so it doesn't matter, or something like that?

From reading about other cars, often when you go too low for your endlinks things break ($). Breaking things and cheap but worthwhile don't go together.

Damnit, I think you really need a degree to fully understand suspensions.

Yeah, my fail. I read your post too quick.

It seems like losing the helper springs and using a longer spring could get rid of the potential for coil bind too.

oilstain

When I re-read my post about that, I realized I didn't give any context and didn't ask it very clearly, but I have been whoring my post count on this thread, so I figured everyone would get it. So I facepalmed for both of us

jacob300zx

I wouldn't go larger than a 7" spring. There's not that much room in a lowered miata. Plus 6-7" springs can be used on future diy coilover projects.

Ok so the outcome is:

Get riceland
Get 250lb QA1 7" 2.5 ID

oilstain

Except!!! It's still not quite right. If there were only 200lb or 225lb 7" 2.5 cheapies.

Though I'll probably just do this, then eventually get a thicker front sway to make up for the bias.

I found 8" 200lb 2.5 ID

oilstain

How much per pair?

QA1s are priced each, but since you need two, I figured that would be a better standard. ($75.76 + shipping for the 250lb 2.5ID 7")

H&R race springs $58.50 each. Sounds good.

he has an AFCO 8" 200 lb. for $20 as well, not sure about a pair: http://cgi.ebay.com/ebaymotors/AFCO-...Q5fAccessories

Cool, I contacted him. I'd really love to see a good cheap source that others would be able to use for the NA Racelands + 200 or 225 rear spring set up.

As long as they don't fall apart more than any of the other models that they make, these will be the next Chinacharger.
