Sorry, but the instructions do not suggest any specific settings for the dampening. IMHO, your settings would have to be based on a personal perspective for the street and track.

 

Please check this thread, at nopistons, for Howard Coleman's post on the EXV suspension (#7). It should answer most questions about these coilovers.

 

^^Actually, the whole thread is very informative. Best to just read the whole thing.

 

so u are runing the apexi spirit rotary? howard said the rear spring rate should be changed? you have any opinion on that? and are there replacement springs yet?

 

Until you have them on your own car how to you really know what they are like. He is looking at the numbers trying to discourage everyone from buy these coilovers. Why? Cause they are cheap they can't be any good?

I have had them on my car for a month or two now. When I set the damping soft they don't feel any stiffer than stock. When they are hard all the way it feels like the whole cars gonna fall apart when you hit a pothole. My car runs on 18s with 35 sidewalls and I really dont think these thing are the end of the world. I have been running them about 8 clicks down from the hardest setting on the street pretty comfortably. Keep in mind I live in New Jersey as well where the roads are crap.

I am not putting him down, just trying to offer a second opinion. I think these coilovers are a good alternative to some of the more expensive setups.

 

Howard is talking about going fast on a track, not how it feels in urban driving....

 

any of you guys with these use them on the road course with R compounds? looking for opinions...

 

Apexi EXV is made in taiwan, it appears to be the same unit that www.meganracing.com is selling for $700-800.

 

May I ask were you got this info? ANd where you happened to find the FD coilovers........

 

I would like to know where you got this information too.

I understand why you would think that. Alot of 32 click dampers out for around the same price but these are NOT the same units as Megan racing. Megan racing first of all doesn't offer a set for the FD. Also their ***** are very makeshift and often don't click or never stop turning. While i'm not sure if they are soley Apexi designed, i'd take a chance and say they are, there aren't many multimarketed sets out for the FD.

 

Prew, I do have these coilovers installed on my car and can say they too work and feel great on the road. Howard did mention that if the spring rates were lowered a bit that they should do quite well in terms of track usage.

 

Count me third in line as curious to know where this information came from.

detail picture of apexi exv coilover, notice the made in tw sticker.

picture of the megan racing coilover, it's exactly the same down to the bolts, only difference is on the adjustment **** (**** is exaclty the same) where apexi exv have words apexi n1 damper printed.

What are the chances of two made in tw coilover being exactly identical. Megan doesn't sell the unit for FD, but you can see how much cheaper these coilovers actually sell for, and the level of technology you are buying from exv.

The clicker assembly they are using have no effect on dampening, the piston rod is internally threaded, the clicker assembly rotates which rotate a hex screw inside, the screw then push down on alittle rod which adjust the dampening using needle valve. The clicker feel/sound is just there so you can identify the clicks, the clicking feel it produces is independent of the actual adjusting mechanism. This is common in japanese coilovers like tein and jic.

My main point is that these coilovers are not similar to Apexi N1 Pro coilovers, which are using a totally different design, and is much superior.

 

the old cliche still holds true i guess.

you get what you pay for

 

i suppose what slingshot said has been proven over and over

 

yes, these coilovers are made in taiwan. My friend also bought a set for his s14 and theres a sticker on each shock "made in taiwan"

 

OH NOEZ now My tv remote and apexi coilovers are both made in taiwan!!


im still considering purchasing these. the price and peformance seem to meet my needs.

 

Hey Guys,

I don't mean to hijack the forum, I'm most likely gonna be buying a set of these next week, but was curious about a couple of things.

There are 3 main variable that is seems you can set with these coilovers: the car's height, the dampening force, and the spring travel. Now, the height is adjusted by turning the bottom part, and I get the purpose, but what setting do I need to change if I lower the car but don't want the car to bottom out in the wheel well (is it the dampening force or the spring travel rate that I need to adjust??

I'm plannin on keeping the stock height, but was just curious to know what variable it is that will reduce amount of travel between the wheel well and the tire when in hard cornering.

Also, do I need any other parts for this install other than the coilovers and tools to do the swap???

 

I don't think you have a clear picture about how coilovers work....

The lower spring mount is adjusted to set spring pre-load -- you'll want just a little bit of tension on the spring to keep it in position at full stroke and to reduce the non-linear range at the beginning of the spring stroke.

Then there is an independent perch below the lower spring mount that is used to adjust ride height. Therefore, you can raise or lower the car without effecting the pre-load on the spring (or reducing suspension stroke).

 

Ahhhhh right on!!! Thanks man!!! That made things alot clearer...
Still a little confused on the right height part... Below the bottom spring retainer, this perch you are talking about.. How does it work? Do you have any pictures or could you go into detail on how it moves up/down?

 

hmm, ok, so then the top adjuster on the barrel of the coilover is the spring pre-load right? then I don't want to set that any more than the minimum pressure required to keep it in place, and then the height is adjusted by rotating the perch on the lower portion of the barrel of the coilover, right?? Then what adjusts the suspension travel/stroke? is it the dampening force dial located at the top of the coilover??

 

The suspension travel/stroke is determined by the spring rate/length and coil spacing! It is not "adjustable". The reason why better coilovers have independent ride-height perches is so that you can lower the car without REDUCING the suspension stroke.

The damping adjuster does just that -- it changes the valving of the damper. It has nothing to do with ride height or suspension stroke (per se).

 

The lower perch is really a lock ring. You rotate the damper and it threads up the body of the coilover. You then lock it in place with the lower perch/lock ring.

 

ok, so I think I get it, the travel of the spring/suspension stroke really doesn't change on the coilover then, the things that can just be adjusted then are the ride height and the ride comfort (I guess the "roll" of the car is also adjusted by the dampening setting?? correct me if I'm wrong here). So the ultimate spring travel and suspension stroke are not adjustable on the coilover?? Thanks for the input, by the way.

So then how is the suspension stroke on this kit in comparison to R1 shocks?? Is there less travel on this kit or am I out of my gourd??

Sorry guys, I think it's blatantly obvious I'm new to the whole suspension tuning thing, thanks for the input though.

 

You're wrong. The "roll" of the car is determined by the spring rate!

No, the stroke is an inherent part of the design of the coilover. Any aftermarket coilover will most likely have a bit shorter stroke than the stock suspension.

Yep. You should really wait on spending $1k on coilovers. I don't understand why you think you need them when you don't understand basic suspension tuning.
