I've got a chance to buy some Mono Flex coilovers for a really good deal (waiting on some more specifics to make sure they're in good shape) so I've been reading into EDFC and came across the new Active system.

It seems pretty sweet, adjusting the dampening based on acceleration/deceleration (speed as an option if you buy the GPS attachment). It's also wireless so you don't have to route cables into your cabin from the adjustment motors.

Anyone here running it or been in a car that had it? at ~$20 more than the regular EDFC it seems like a no brainer to buy it (you could run it in manual mode if you didn't want the active part) but I'm curious if the GPS add-on would be worth another $75 for the speed variable dampening.

 

The concept is cool. Makes me think of the what the Porsche has, but without the height adjustment. The questions I have is, how quickly does it adjust settings and what is the durability of the unit?

 

The video shows it changing pretty quickly while dring around a track. Not sure about the durability of it all though.

 

dumping adjustment according to vehicle speed - sounds really good.
normal EDFC is very easy to use.

 

Curious to hear why you (or anyone else that wants to share) thinks this is beneficial for performance.

 

my Monoflex felt like they need different rebound at normal speed and very high speed.
i'm sure it has blow valve like KW and Ohlins have for high speeds.
so adjusting stiffness according to speed could help.
of corse is just a "patch" instead of real solution for the problem

 

This sounds very gimmicky to me and would never waste money on it. True active suspension is much more complicated than just a GPS sensor that adjusts rebound on the fly.

 

gimmiky - yes.
but gimmiks and gadgets sell.

KW also have something similar wich maybe usefull to adjust settings for specially bad roads or for track.

what do you mean by true active suspension?

 

Agreed, but gimmicks are sold by taking advantage of consumers who don't know any better. When applied to suspension, a topic already hard to understand by consumers, it borders on irresponsible in my opinion.

Another company out there had a similar gimmick, which was to tie the damping (rebound only) to the vehicle's VSS. Which meant that when you were doing 115 down a straightaway, rebound damping gets maxed. You get on the brakes hard to enter a hard turn at 45mph and that same damping drops to softest. The assumption being made by this "technology" is that regardless of ANY VARIABLE other than speed, you need to reduce damping all around. Think about that for a second.

 

i don't if it workes well in this case. i hope it does.
anyway - i think it's probably better to go for the newer product. especially if the price difference is so small.
