Hi guys,
Im looking at these 2 coilover for my evo X and i still don't know which one would suit me better, so i was wondering if you guys can give me some advise? My car is my daily driving car but I do go to the track when the event is good, i also like to canyon driving too, so which one will be good for me? please feel free to say anything.
thanks
Nick

 

ast 4100 since you are very likely to get custom valving when you order a set.

 

Either would proably make you happy.

There is a learning curve with the KWs because of the double adjustment while the ASTs are single adjustment...so easier to adjust but limited.

YOu could consider Robi Spec's KWs that will be custom valved and springs.

AST will give you any spring rate you want. Robi has but a lot of testing into his setup. There was some R and D with the ASTs but not sure to what level.

Both are quality products.

 

AST. It is a better coilover, at the same price level.

 

AST is better for track purposes, I think that the V3s would fit your needs perfectly.

 

COmpletely unbised opinion ;-)

Robispec

Either KW or AST. they both have advantages depending on intended use.

What do you consider the advantages of each ?

 

Pure longevity the Robispec/KW SS casing and twin tube has an advantage. (fewer wear parts)

Robispec/AST monotubes have less weight and cool better.

Robispec/KW double adjustable (can be a disadvantage too lol)

Build quality and parts availability exellent in both cases (helps when there is a problem).

Do you end up running similar spring rates?

Some people seem to think you higher spring rates effect ride quality less on monotubes.

 

Opinion backed by testing.
The KW twintube base valve system can work better than a monotube in the under 1"/second range and this supplies better "insantanious hydralic resistance to movement" and allows a softer spring rate (also the stiction forces are less so the damper/spring system feels smoother.
Monos have a higher initial "breakout force" and so they usually use a bit higher inital spring rate to stabilize the car.

 

So for the applications most often encountered by most here, what are do you generally recommend?

Daily driver who wants the car lower w/no loss or a bit of improvement in performance without loss of ride quality?

Sometime/occasional track or auto cross guy whose car doubles as daily driver?

Mostly track guy who may use car occasionally or never as DD or lives where roads are smooth?

How about if any of these have to deal with very bumpy roads/tracks?

 

^^^ thanks for keep asking question, so i can learn more! but rightnow money is really important fact to me... the kw v3 and ast has $450 different...so i don't know if go with the lower price one(KW) or with go AST which easier to set up (which i really want). i know both of them is good so right now is lower price but higher to set up and higher price but easier to set up.
what do u guys think? and i don't know how does the double adjustment works so i don't know if i can tune it right...
thanks
Nick

 

or if anyone can talk about how does the double adjustment works and how to tune it right?
thanks alot

 

I think the AST has an advantage on the track, but that's just me.

Twin-tube KW with lower spring rates is nice for a daily driver, but both are very good when set-up correctly for a specific intended usage.

im on the same page. Im sure if Robi or GTWORX set up a set for you,for your needs you will be not dissapointed.
I just cant help , to like the AST better with my previos experience. Also since it easier to set up for rookies , has less room to ruin the ride ...
And we know that is happens , when someone just start to dial coilovers in a way he thinks the ride will be faster... LOL
