Ok that is a start, I'll make note of it in the chart, thanks!

 

Updated the list with the different variants of BC Racing Coilovers, I also got a PM with quite a few more choices which I'll try to update on the list over the next few days once I verify the details.

 

coltspeed springs for bilstein

Front: Lowers 30mm～35mm Spring rate：F2.7～5.0kgf/mm　
Rear: Lowers 15mm～20mm　Spring rate：R2.3～5.0kgf/mm

 

I'll check those out and update the list, thanks!

 

I'm pretty sure you can request any spring combos you want and they will valve the shocks for you. If there are some standard numbers that they recommend I have yet to find a link to them but I guess I could ask Ryan Gates. They are definitely top notch coilovers although not in everyone's budget.

 

you need to edit that - endura-techs come 7k/5k from the factory, but can come with stiffer springs on request

thanks!

 

Springs ...................... Front Rate ........ Rear Rate ...... Front/Rear Drop ...... Street Price
Swift Sport Mach ........ 2.7 - 4.3 kg ...... 2.3 - 4.4 kg .......... 1.0" / 0.6" ................. $350
Tein S-Tech .................... 4.2 kg ............... 3.8 kg ............... 1.4" / 1.0" ................ $220

Noob question, since the S-Techs have a higher spring rate. Does that mean it's a stiffer ride than the Swift Springs?

 

The tein's do not have a higher spring rate, rather a steady rate where as the swift's are progressive. The swifts start off softer but can get stiffer than the tein's as the springs compresses. In other words, they are soft during cruising and hard when you hit the corners.

 

The whole progressive spring thing is a bit hard to pin down. Basically on smooth roads the lower spring rates mean the factory shocks control the springs just fine, not that it's a challenge on a smooth road! On moderate bumpy roads the spring rates are probably slightly high for the shocks but within limits so it's mostly decent handling and response. Get onto a bumpy road and you get spikes of higher spring rates kicking in that are uncontrollable for several bounces by the stock shocks and you can get that bouncy feeling.

That's one of the major reasons I finally moved to coilovers since they have linear spring rates and adjustable shocks is much more predictable versus progressive springs and non-adjustable shocks.

 

Interesting - Espelir ASD springs for the Evo X. Rear is lower than front - doesn't sound good right off the bat!

One more for the list!!!

Progress also makes springs for the Evo X

http://www.evoxparts.com/evoxparts/P...-X-p-525.html#

- Front drop: 1.2" (Front rate: 260 lbs/in)
- Rear drop: 0.8" (Rear rate 230 lbs/in)

I am guessing these are linear rates?

 

i see that with the COBB springs they advertise on lancershop too...the drop in the rear is bigger than the front...i emailed the site and asked why b/c for most springs, it's the front that offers lower drop than rear (and that's how it should be)--right?

anyway, the rep at lancershop didn't know why either...lol

 

From what I understand the Evo is somewhat raked from the factory. Swift and Works do not alter this rake and from everything I have read, the rake should remain unaltered as it affects the cars handling characteristics and one reason why Swifts are so highly recommended!

 

Reducing the rake is better for high speed turns. Keeps it stable. For performance reduce the rake a little if possible.
