Okay I know there are a million threads about this but...

I'm between the KYB's and the Koni's for dampers: How does the height adjustability work on the Koni shock?
I've used AGX's b4 on my Subaru and loved them.

I'm up in the air on springs, S-tech, racing beat, eibach... I want it to be pretty low obviously, I'll be doing rear upper shock mounts to get the travel. Not looking to pay too much right now, otherwise i'd go with an adjustable height spring like the Ground control.

Who reccomends what and why? I will be daily driving this car but I'm still young and I've driven fully stripped cars for months on end... a hard suspension isn't a problem.

An aggresive look would be desireable, but handling takes precedence of course.

Let me know what you think

I have konis and FM spings/sways along with the FM mounts. I really like them.

The konis are hight udjustable by having three grooves machined in the shocks, where you have a snap ring that holds the perch, It comes with three groves.

I have mine on the middle perch all the way around. I think that makes it about 1.75" lower than stock. Just high enough that I dont scrape (I hit everything on the bottom perch). It is also possible to adjust the ride hight on the car, but it is very dangerous and I wouldnt recomend it.

EDIT: since I think they changed the desine I will specify that I have FMs old springs, slightly stiffer and slightly lower (I think).

I'd go with the FM springs, since it seems to give the most drop and has higher spring rates compared to the Tein and RB.

(got this info from each company's site)
RB Drop: F/R .33/1.0in
Rate: F/R 30%/20% stiffer over stock

Tein Drop: F/R 1.14/.75in
Rate: F/R 230/170lbs/in

FM: Drop: F/R 13/13.25in center of wheel to fender lip
Rate: F/R 318/233lb/in

but if I had the money I'd get the ground control coil overs for my konis. Maybe someone with experience with these springs will chime in. The only springs i've experienced on a Miata are stock and OEM like spings (Koni won't reveal the actual spring rates) that came with my Koni shocks. :roll:

Nope, No matter how hard core you bug their tech guys they will only tell you "Its slightly stiffer then stock, and since they are progressive rates they have such a broad range its impossible to get a spring rate". They even said it was impossible to get a spring rate range.

thanks for the info

FWIW, my rear AGX's only lasted me a little less than two years.

And this is why I like FM and GC coils: http://www.tampabaymiatas.net/Misc_Pages/Miata Suspension 201.htm (scroll down to the springs section)
