Suspension Techniques Coilovers?

[asiandude74]

I was set on getting KW variant 1 coilovers but I found these ST coilovers and was wondering if anyone has them? And if they are any good?

They say their basically KW variant 1's but different materials or something for a cheaper price.

Interesting.
Looks like you can get them for $891 http://www.ultrarev.com/90706-st-p9.html

Basically V1s without the stainless and shorter warranty.

The one big difference I see is the ST coils have a common part number between the speed 3 and Mazda 3
The KW's have different part numbers for the MZ3 and MS3.

For that reason alone I would be tempted to go KW v1 over the ST product.
The coils have little enough free travel as it is without having them under sprung.

Unless you can confirm the spring rate of the ST vs the KW MS3 and MZ3 products to your satisfaction.

If price is an issue. PM all MSF vendors for a price on the KW's, my guess is they wont be much more than the discount ST brand

I wouldn't do ST for reasons mentioned above. MS3 nose is 150 lbs heavier with an extra 3-5 lbs of unsprung weight per corner. Stick with V1's.

Yeah i agree. Just trying to find the spring rates for the STs vs. the KWs. Cant seem to find them anywhere!

Call KW.

I'll tell you this, dont buy any coils sprung less than MS coils for the MS3

I found the kw spring rates: mazda3=Fronts 340 Rear progressive
Speed3=Fronts 400 Rear progressive


What are the spring rates for the ms coils?

edit:found the ST spring rates which are Fronts 345 and Rear progressive.

So that throws ST out the window. Gotta find me some KW V1s now.

You really shouldn't have to. These are made specifically for the MZ3 not the MS3. That tells me they are the same rate as the V1's for the MZ3 (340F and 290R IRRC).

EDIT: Treed.
