lowering spring specs for Yaris

[botchilah]

Since I originally posted asking about different lowering spring rates for the Yaris NCP91 chassis code, I started searching around until I realized I have a Hyper Rev magazine for the Yaris (duh!)

So I copied the rates and drops and am putting them here. MODS I hope you make this a sticky because this would be most helpful for everyone!

Progress Group Springs – 110 lbs/in front and 130lbs/in rear
2kg/m front and 2.3kg/m rear

* The specs for the Tanabe NF210, DF210 and Progress Springs I took from the Microimage website. The rest I took from my Hyper Rev magazine.
** I used 56 to convert kg/m to lbs/in vis-a-vis.
*** Hyper Rev lists a range of the actual DROP so I simply put in the lowest drop but the variance is only 5mm from highest possible to lowest possible drop of the springs.
**** All spring rates and drops in inches are rounded off to the nearest 100th decimal for simplicity's sake. At most you're looking at 0.02 variance.
***** If there are any errors please do post up and tell me so we can correct it. Thanks!

If anyone wants the drops and spring rates for popular lowering springs for the older Yaris / Vios platforms and chassis, PM me your chassis code and I will post it here as well. Right now these are for all NCP91 chassis Yaris.

aren't tein s tech's closer to 2". i know for a fact im not rolling on an 1.5" drop.....

[cali yaris]

^ Yes, I've heard that too, more like a 2" drop.

I don't think there is a GF210 for us.

H & R is another spring, but they don't publish a rate.

And the new springs from China that I have, 1.75" drop (more or less) and 4k front, 3.1k rear.

[Pitt Yaris]

Good stuff, this should def be a sticky after some editing and more springs/rates.

So we need H&R, garm's springs from china(tigertec right?), megan racing, eibach, TRD, and probably some more I'm forgeting?

Awesome info though, and a complete list should help with the amount of "which springs should I get" threads.

[detroiter]

I thought the AOE Tigertecs were about 1.5" or that's what I remember from the test information you were telling me about? I guess either way I'll find out soon just how low is low! lol

[cali yaris]

yeah, that's why I said "more or less"? I only have a picture to go by until my TEST SUBJECT comes through. :: coughs politely ::

I got the specs from my the Japanese Hyper Rev magazine (for those who don't know, it's like a 3rd party catalog that lists all imaginable aftermarket parts and accessories for specific types of cars published by Mook's Publishing in Japan) and/or our online shop vendors.

As I've said, if there are any mistakes, let me know so we can edit it :) I'll go check on those Megan springs right now.

RE GF210, there's an application listed in Hyper Rev for the NCP91. Might be a JDM only product? I can double-check with my local Tanabe supplier though.

[Pitt Yaris]

Yea, I think I read s.techs are 1.8 or 1.9 drop

[Keith Tinari]

Is there another to show us what shocks and struts will net the best or most agressive combo yet?

[mrbond]

don't think there is a GF210 for us.


Tanabe shows that the GF is available for the N91, so it is for us. I have no idea why these aren't in the states yet.

[mrbond]

Is there another to show us what shocks and struts will net the best or most agressive combo yet?

Nope. There's a good list of available dampers, but no rates whatsoever; only prices. The struts/shocks available for the N91 are as follows:
TRD Sportivo
Bilstein Premium Order Line
KYB SR Special
KYB Lowfer Sports
el-Sport Type Standard
el-Sport Type Adjustable
el-Sport Type Adjustable2

[MUSKOKA800]

TRD Red. 1.2" lower front and rear according to manf.
Real world... shortly after settle-in and still after 40,000 kilometers, closer to a 2" drop in my '08 sedan when compared to the same model with stock suspension which parks beside me daily at the office. His looks like an off-road set-up in comparison. Yuck!

[j2ip]

I am having a same issue. I want to change other brand. Anyone have idea?

[chongopants]

If anyone has a set of springs or rear sway bar for sale let me know. I am trying to stabilize the car in turns and dont have a lot of cash.

[cali yaris]

the GF210 is made by Tanabe, but not sold in the USA.

You can add TigerTec springs to the list:

4k front/ 3k rear
1.7" drop

[chongopants]

cool, well I am looking to spend 25-50% of retail... pm me and let me know what you have to offer price wise.

[Flipper_1938]

Anybody ever find out what the spring rates are for the Megan Racing lowering springs?

[cali yaris]

Progress are no longer made
We can't get the GF210

MI springs are missing from the list (old list!)

I'll ask Megan about their rates.

[Flipper_1938]

According to Megans tech line:

Front 126 ft lbs
Rear 144 ft lbs

Those springs should be pretty soft when compared to the other drop springs.

Edit: Ride is nice.
