i have an 06 coupe which i am trying to lower. Which brand/company would u guys go for and which one? need something where i can drop it and then raise it back up to factory level in winter time. just curious what everyone has on their G's and which one would be the best for the g's and how smooth of a ride do u get with suspension upgrade?

tein and hks are both great systems, all preference imo

Will these coilovers be for any track use, or just daily driving?

daily driving.

with tein they're edfc compatible which easily accesses to the dampening force of the coilovers..

hks.. you gotta get to each dampening turner in order to chang the dampening force

personally i'd go with the tein.. i love the flex's. had them on my subaru

EDFC is a gimmick, not to mention that I'm YET to see a clean install on any car. A top adjustable coilover completely eliminates the need for EDFC.

The Flex's sound great on paper if you drive on glass-smooth streets.. would probably be my choice, but if you live in pothole central those spring rates will get to you eventually.

Tein coilovers are top adjustable. Have you tried to adjust your rears from the top? You CANT. The top of the rear strut is completely enclosed, meaning you would need to remove your coilover to adjust it.

The EDFC is a great tool, and I've done about a dozen CLEAN installs. Its not that hard to do a clean install in our cars... run the EDFC wires under each door sill front to rear, the fronts go through a grommet on the firewall and into the engine bay. If you are getting ugly installs, then you're installer is either lazy or incompitent.

FLEX will be rough for most users daily driven. But you might get used to it. Its awesome on the track though. I would recommend CST for the daily driver if you don't ever track it.
