Does anyone know much about these? are they decent and are they single or double tap coilovers? Thanks for any help.

double tap? if you mean mono-tube / twin-tube, its a twin-tube design.

 

^ what does twin tube mean?? Are some coilovers height adjustable on both top and bottom and some just on the bottom??

 

Seriously?

I've never heard anyone call anything coilover-related a "tap"

Twin-tube is a type of damper. There's another tube inside the body tube that the piston and valve sits in. On JIC's line, the A1's are twin-tube and the A2's are mono tube. A twin-tube damper generally has a smaller piston diamater which isn't really anything to brag about.

You're getting this confused with "double adjustable", which for all these low end coilovers means 2 places to adjust the ride height. (the other "double adjustable" means 2 places to adjust the damper). This type of mounting will have a threaded spring perch and a threaded lower mount. Generally it's these threaded lower mounts that can get you extra low.

These appear to be single adjustable for ride height.

 

^Yes, Thank you for clearing up my ignorance Ar ethese listed above double adjustable? Also, which is better for getting low, Mono or twin tube? Thank you!

 

Monotube is superior to twintube, read more here: HKS USA HKS Hipermax Monotube vs. Twintube

 

With adjustable preload, it should not matter. Go with the stiffest springs (thus little dampening) you can get if you want to go low-low.

 

So strike one against these as they are Twin tube. Now if they aren't double adjustable I am gonna pass on them.....

 

There generally isn't a "which will go lower" when talking about twin-tube and mono-tube. Strictly speaking, the twin-tube is a more compact design, which would imply more lowness. On an S14 application where the struts can really be as long as they want (rears have all the room in the world, fronts can go down until they hit the wheel/ground) this really has no merit in a lowness debate.

 

They will be going on my Q45. So then the real question is if they are double adjustable...
