TEIN springs
Does anyone know where I can buy TEIN springs from in NZ? I am after some 8kg springs to fit a NA.

you need to consider the lengths of the springs also. as there are different free lengths available.
fatcat motorsport has some good advice regarding rate and length of springs and also the springs are easily available on ebay..
so youd get something like an 8 kg front with a (6.5"????) length and a 5 kg rear with a (7.5"????) length dont quote me on the lengths im just quoting from memory. i have a funny feeling that the standard is 7" front and 8" rear for most threaded adjustable coilovers.

Here is Tein USA's list of standard spring prices http://www.tein.com/products/standard_s ... _list.html
You'll want a spring that has sufficient stroke that it won't get coil bind when the strut is fully compressed.
A stiffer spring will compress less with the same amount of force, so going to a stiffer spring in the same length will make the car sit higher, and also be higher in the damper stroke (more bump, less droop). Lowering the perch further may lead to uncaptive springs, so you may need a shorter spring (which means less stroke) or to use a helper spring that keeps the main spring captive when the perch is lowered.
For example, my Tein Mono-flex struts have 6kgf/mm 175mm (~7") front springs. These have a stroke of 110mm.
Assuming a 250kg corner weight and 0.66 motion ratio, the spring will compress 63mm with the car at rest, and leaves a good balance between bump/droop travel (adjustable with spring preload)
If I were to upgrade to 8kgf/mm springs, the spring will compress 47mm with the car at rest. If I used the same length springs, it would leave the car sitting about an inch higher and raise the damper stroke about 15mm, both probably undesirable. I could probably get away with going to the next size down, which would limit the stroke to 91mm (leaving 91-47 = 44mm for bump)... I'd need to measure everything up and check damper specs to be sure.

I have got my springs from the states in the past, always has worked out cheaper if you don't need them right this very instance.

If they're teins on billies, they should be standard 65mm id competition springs.(pretty sure most tein coilover one's are.)
If that's the case, then obviously you could use any comp spring (not just tein) so just get dobi or kings one's, any length from 180mm to 400mm from memory, and from 150lbs to 1100lbs...
The advantage of this is that Both stocks and autolign will usually exchange them for a different rate (sometimes they do charge a small fee) if you put them in and find they are wrong, as long as they are still in new condition.

Re: TEIN springs
Everyone seemed to go a little off topic there. You can buy Tein springs in NZ from Autolign, which have lots of stores around the country, or you can ring Racelign in Auckland.warrior wrote:Does anyone know where I can buy TEIN springs from in NZ? I am after some 8kg springs to fit a NA.
If you have trouble getting a the parts that you want through them or feel the price is too high then give me a buzz, as I deal with them on a daily basis and can swing a good price.
P.S. 8 kg springs are far too heavy for an MX5
Ok, the NZ places want $400.00 with a 12 week wait time...yeah nah.
I can get 8kg TEIN springs from TRACKDAG racing for $200 delivered, but I have one question.
I have TEIN BASIS adjustables and want to put the 6kg springs that are on the front onto the rear and the new 8kg springs on the front.
The question is: Does anyone know if the 6kg springs I have on the fronts are the correct length to swap to the rear?
I,m sure they are but just want some thoughts.

generally speaking the difference in length is about 1.5 front/rear. you might be able to get them to fit depending on your threaded perches and what your ride height is, but you may get coil bind issues.infact im pretty sure youll get coil bind putting fronts into the rears. the eibach springs on ebay are cheap enough and there are even some others that the guys on miata turbo.net use which i cant think of the name right now.
oh and dont forget that going stiffer springs will mean you may have to disconnect your rear sway bar or get a much stiffer front bar and bar mounts.

According to tein.co.jp, you should have 6kg/mm springs on the front, 5kg/mm or rear; both 200mm length and 70mm ID. (front part # SB060-01200)
If you put the 6kg spring on the back, it will compress ~8mm less than the 5kg spring (assuming 250kg corner weight), leaving the car sitting higher and closer to full damper extension.
Depending on how much preload the current rear springs have, you may be able to lower the perches to accommodate the 6kg spring and still keep it captive at full extension.
(e.g. the reference specs for my Mono-Flex dampers call for 19mm of preload on the rear springs. If I wanted to swap my 6kg springs on the back I would need to reduce the preload to ~10mm but the springs would still be captive)

200mm (8") sounds waaaay to long. Especially for the front.
8kg 200mm will have you entering the local 4wd rally.
general rule of thumb is 8kg/6" length front and 5kg or 6kg 7" for the rear depending on spring perch used in the rear.
the eibachs on ebay and the QA1 from summit racing (EXCELLENT service) are a good bang for buck spring.

yes the NB tophats will allow you to run longer springs, but 8" is still too long for the front and 6" is pushing coil bind territory in the rearbuilt4speed wrote:Or dobis or kings which are available locally. My fronts are 180mm long with ample clearance. 200mm wouldn't be an issue.
I do run nb top hats which will make a difference.
